Harrison Ford revealed that he's seen the movie and thinks it's "phenomenal", but skipped out on the premiere with the rest of the cast because he didn't want to steal Alden Ehrenreich's moment of glory.
Although originally brought on board to complete the film after Phil Lord and Christopher Miller had been dismissed due to creative differences, it was widely reported in October 2017 that Ron Howard had re-shot more than 80% of the movie.
Tobias Beckett wears the guard disguise as seen in Star Wars: Episode VI - Return of the Jedi (1983), when it was worn by Lando Calrissian in an attempt to save Han Solo from Jabba the Hutt. The disguise is likely stored on the Millennium Falcon.
Han is seen speaking to Chewie in the Wookiee language. This is the first time a non-Wookiee is seen speaking the language, as well as the first time the language is translated on-screen with subtitles.
During an interview on IMDb Me (2018), director Ron Howard explained that he always tries to give his wife, Cheryl Howard, a cameo in his films since she is his "good luck charm". She had indeed shot a scene for this movie, but this scene ended up being deleted from the final cut. One day, Howard shared his regret over being unable to include his wife in the film with special effects technicians at Industrial Light & Magic. They subsequently shot her against a greenscreen and digitally inserted her into another scene in the movie to give Howard his "good luck charm".
The movie finally addresses a long-time fan theory about the series. When Luke and Obi-wan meet Han Solo in Star Wars: Episode IV - A New Hope (1977), Han boasts about the Millennium Falcon's speed by claiming that it was the ship that "made the Kessel Run in less than twelve parsecs". However, people quickly pointed out that a parsec is a measure of distance, not time (one parsec being approximately 3.26 light years, or just over nineteen trillion miles). Star Wars printed materials explained that the Kessel Run is a route of fixed distance, but Han was able to navigate it much quicker, by finding a short-cut that limited his flight to somewhere at, or over, twelve and a half parsecs. This fact was again referenced in Star Wars: Episode VII - The Force Awakens (2015) (2015). This movie agrees with that, by showing that the Kessel Run is normally twenty parsecs long, and runs along a series of corridors through a nebula. Han managed to traverse the nebula itself, risking the debris, very large creatures, and a phenomenon called "the Maw", and making it to the other end in twelve and a half, to just under thirteen, parsecs (but he says he "rounded it down" to twelve). This film reveals that it was actually slightly more than twelve, but Han was rounding down. Still an impressive feat, considering that Lando says it's impossible to make it in less than twenty.
Han Solo was originally going to appear during the Battle of Kashyyyk in Star Wars: Episode III - Revenge of the Sith (2005), in which an orphaned ten-year-old Han, who is being raised by Chewbacca, helps Obi-wan Kenobi to locate and find General Grievous by finding part of a transmitter droid that was sending signals from Utapau.
Lando Calrissian says to Han Solo, "I hate you" to which Han replies, "I know". This is a direct reference to Star Wars: Episode V - The Empire Strikes Back (1980), when Leia says to Han, "I love you" to which Han replies, "I know".
Alden Ehrenreich was the first actor to audition for directors Phil Lord and Christopher Miller. The directors said in July 2016 that while they liked a lot of the other actors with whom they read, they increasingly said, "The first guy we saw was the best for the part", and that led them to eventually cast Alden as Han.
The Imperial March can be heard in-universe playing on the recruitment film at the Corellian spaceport and is in a major key to sound more uplifting. The same variation of the song was used during a parade in Star Wars Rebels (2014), season one, episode seven, "Empire Day".
Vos offers his guests Colo Claw Fish to eat on-board his yacht. The Colo Claw Fish is one of the sea monsters that live in the planet core of Naboo, and was previously seen in Star Wars: Episode I - The Phantom Menace (1999).
When Beckett, Rio, Val, Han, and Chewbacca talk around a bonfire the night before the train heist, Beckett disassembles a rifle in some pieces, turning it in a blaster, that he gives to Han. This is Solo's famous blaster seen in Star Wars: Episode IV - A New Hope (1977), Star Wars: Episode V - The Empire Strikes Back (1980), Star Wars: Episode VI - Return of the Jedi (1983), and Star Wars: Episode VII - The Force Awakens (2015).
L3-37 was achieved through a combination of practical and computer effects. Phoebe Waller-Bridge wore a costume that consisted of the droid's body parts (head, chest, legs, and arms) with a green skintight suit underneath. The green suit was later removed in post-production and replaced with mechanical parts, such as cables and wires.
Just before attempting a very risky maneuver in the Millennium Falcon, Han says "I have a really good feeling about this". In the previous Star Wars films, characters (including Han) have said "I have a bad feeling about this".
Phil Lord and Christopher Miller left as writers of Flashpoint (2020) to work on the Han Solo film. Unfortunately, they left halfway through production along with original editor Chris Dickens, citing irreconcilable creative differences with producer Kathleen Kennedy and co-writer Lawrence Kasdan. A studio report reveals that Lord and Miller's comedic screwball tone and freewheeling approach angered Kasdan, who wanted the film shot in the way it was written. It also angered other production department heads who complained directly to Kennedy. The final straw came during the two-week break while production moved from the UK to the Canary Islands; Kennedy and Kasdan together with the replacement editor Pietro Scalia were shocked at the footage, and decided then to fire Lord and Miller.
When Beckett, Qi'Ra and Han are discussing Imperial stashes of hyperfuel that they could steal, the name Scarif comes up. Scarif is the name of the Imperial planet that houses the plans of the Death Star in Star Wars: Rogue One (2016).
Dryden Vos' original concept art portrayed him as a dinosaur, bird-like figure. With the development of a love triangle between him, Han, and Qi'ra, his design became more humanoid, majestic, and handsome in order to evoke more jealousy from Han.
During an interview on The Graham Norton Show (2007), Phoebe Waller-Bridge stated that prior to her casting, she had never seen a Star Wars movie, and didn't know what a droid was. Phoebe Waller-Bridge didn't realize L3-37 was a droid when she auditioned, and so she decided to play L3-37 as a human in her audition. It was only when one of the directors asked her if she could be more "droid-y" while making a mechanical hand gesture that she deduced that droids are robots. Although the casting directors asked her to try it again, they liked her original interpretation of the character and gave her the part.
The opening scene on Corellia and the opening scene in Rogue One: A Star Wars Story (2016), where Galen Erso is taken by Krennic, both take place thirteen years before the events of Star Wars: Episode IV - A New Hope (1977).
After director Ron Howard came on board, there was a big question on whether the directing credit would be given to him or to original directors Phil Lord and Christopher Miller, as Director Guild rules stated that a person who shot ninety percent of the film would be given the credit. Howard eventually re-shot eighty percent of Lord and Miller's footage; with a possible impasse looming, it was eventually decided that as a compromise, Lord and Miller would be given Executive Producer credits in exchange for Howard getting the directing credit. Much to the surprise of everyone, they didn't challenge the decision.
To pay homage to Star Wars: Episode IV - A New Hope (1977), Beckett is playing a game of battle chess with Chewbacca. Beckett suggests a move and when Chewbacca makes it, he takes out the piece and wins. He tells Chewbacca to plan his moves better. R2-D2 made that same counter to Chewbacca's move, except when Chewbacca gets angry, Han suggests letting the Wookiee win. When C-3PO protests, Han explains that Wookiees can tear arms out so C-3PO tells R2-D2 to let the Wookiee win.
Artists used a cast of Chewie's head and bone structure to create the emaciated mine Wookiees on Kessel. Artists tested out various colors, hair loss patterns, and injuries to show not only variation amongst Wookiees, but the hardships they experienced in the spice mines.
The poem on the final Enfys Nest helmet design, penned in stylized Aurebesh (the most common written language in Star Wars, first introduced in Return of the Jedi), translates to, "Until we reach the last edge, the last opening, the last star, and can go no higher."
L3-37's name comes from the writing system known as leet. A popular form of writing on the Internet, it is when the writer uses numbers and symbols to replace similar looking letters (i.e. turning elite into L-EET and then into 1337).
First Star Wars movie where Chewbacca reveals his age: one hundred ninety years. It implies that he's two hundred years old in Star Wars: Episode IV - A New Hope (1977), two hundred three in Star Wars: Episode V - The Empire Strikes Back (1980), two hundred four in Star Wars: Episode VI - Return of the Jedi (1983), and two hundred thirty-four in Star Wars: Episode VII - The Force Awakens (2015) and Star Wars: Episode VIII - The Last Jedi (2017).
In the scene where Qi'ra and Han are eventually caught kissing in Lando's cape closet aboard the Millenium Falcon, Qi'ra is trying on Lando's blue cape with a black collar that he wore in Star Wars: Episode V - The Empire Strikes Back (1980).
Two figures in the holochess game were scrapped in the original Star Wars film, but ended up making it into Solo. Crew used Joonas Suotamo's frustrated performance of Chewie as an explanation for the missing pieces in Star Wars: Episode IV - A New Hope (1977): Chewie's swipe at the game pops a couple of buttons off the table, thus causing two characters to be "lost" from the set.
When Beckett changes the sniper rifle into the blaster and tosses it to Han, it is a direct reference to the creation of the original prop. The famous DL-44 Blaster was created for Star Wars: Episode IV - A New Hope (1977) using the Mauser C96 prop wielded by Frank Sinatra in The Naked Runner (1967). In that film, Sinatra's character disassembles his sniper rifle into the base Mauser to store it in his case. The same prop can be seen in Sitting Target (1972), with the scope attached, but missing the "heatsinks" and other accessories.
Mudtroopers were modeled similarly to AT-ST pilots in that they did not wear face masks. This decision was necessary in order for audiences to identify and see Alden Ehrenreich's face easily on Mimban. The eventual helmet and gas mask design was inspired by early World War I helmets.
For the alien Six Eyes, accelerometers and gyros were installed into the puppet's head to sense where the performer was looking. The all-around eye and eye-rod movement reacted as the performer's head started to move left, so the eyes would all go left and look with him. As he moved right, there would be a built-in hesitation before looking to the right, creating a more realistic experience on set and on screen.
The first Star Wars Lucasfilm, Ltd. franchise film to not use the phrase "I've got a bad feeling about this." This phrase was first used in Star Wars: Episode IV - A New Hope (1977), and first spoken by Luke Skywalker when the Millenium Falcon approached the Death Star, and then by Han right before the trash compactor began closing in on them while on the Death Star. It had been used in every franchise film including Rogue One: A Star Wars Story (2016), and even spoken by BB-8 early in Star Wars: Episode VIII - The Last Jedi (2017). In keeping with Lucasfilm Ltd. traditions, it was also spoken by Indiana Jones in Indiana Jones and the Kingdom of the Crystal Skull (2008). However, instead of using that signature line in this movie, Han says "I have a really good feeling about this."
The second film Warwick Davis has worked with Ron Howard. Howard directed Davis in Willow (1988). Warwick Davis originally appeared as an Ewok in Star Wars: Episode VI - Return Of The Jedi (1983), and as an extra, in Star Wars: Episode I - The Phantom Menace (1999).
Director of Photography Bradford Young worked closely with Panavision to find old lenses that suited the gritty look of the picture he was going for and to refine them for use on the film. By removing anti-glare coatings and slightly detuning the lenses, Young was able to achieve the imperfections he was exactly looking for.
In the droid arena scene, L3-37 says to Lando "They don't serve our kind here". This is a nod to the Cantina scene from Star Wars: Episode IV - A New Hope (1977), where the bartender says to Luke "We don't serve their kind here!", referring to C-3PO.
According to the film's Official Guide Book, the rules of the sabacc card game are as follows: There are sixty-two cards in a deck, and each card represents a number value ranging from -10 to 10. The goal of the game is for a player's hand to add up to zero. Players bet depending on their confidence in their hands, similar to poker. After each betting phase, a pair of dice are rolled. If both dice have the same image, or "doubles", all players must discard their hands and redraw a new hand. The player who draws exactly zero is the winner. This differs from the version published with the old West End Games roleplaying game adventure "Crisis On Cloud City", which uses four suits of cards each numbered 1 through 15, and two sets of face cards numbered zero and certain negative numbers, with the goal to add up to 23 without going over, going under -23, or zeroing out completely, or to compile a hand called an "idiot's array" with consists of cards with the values 0, 2, and 3 to literally spell "023" as depicted in Star Wars Rebels (2014) season one, episode eleven "Idiot's Array", with dice being rolled to force a random exchange of cards to simulate the cards randomly changing value on the players due to them being electronic within the franchise's universe.
The word "Wookiee" was inspired by Bill Wookey, a friend of actor Terence McGovern. McGovern portrayed a robot cop in George Lucas' THX 1138, improvising the line, "I think I ran over a Wookiee back there."
Han bears a scar on his chin, which is only barely noticeable in some shots. It's a recreation of the scar Harrison Ford has in real life, which is also visible in every Star Wars movie he appeared in.
Lando's mentioning of the Sharu (an ancient species), the Oseon system, and the Starcave Nebula are callbacks to the 1983 L. Neil Smith novels "Lando Calrissian and the Mindharp of Sharu", "Lando Calrissian and the Flamewind of Oseon", and "Lando Calrissian and the Starcave of ThonBoka", respectively, which detail Lando's adventures prior to losing the Falcon to Han, and where he travels with a droid co-pilot. The crystal skull in Dryden's office is also a reference to the cover art of the 1980 Brian Daley novel "Han Solo and the Lost Legacy", set prior to the job that gets Han in trouble with Jabba the Hutt.
The image of the Star Destroyer in the beginning sequence of Solo is meant to evoke the opening sequence of A New Hope-instead of seeing a giant Star Destroyer looming in space, Solo features a segmented Star Destroyer being constructed on Corellia.
ILM animation provided hyperspace footage that was projected on set during scenes in the Falcon's cockpit. Not only did this help actors feel immersed in the Star Wars world, but it also helped the camera department understand how to light the area and photograph it.
Han's last name is given to him by an Imperial recruitment officer on Corellia when enlists. it's a hidden nod to The Godfather: Part II (1974), where Vito Andolini is renamed as Vito Corleone by a New York City's custom guard on Ellis Island.
During the Kessel Run, music cues can be heard from Star Wars: Episode IV - A New Hope (1977) and The Empire Strikes Back; specifically the Tie fighter attack after the escape from the Star Destroyer, and the chase through the asteroid field.
Twiggy, Studio 54, and Vogue magazine during the mid-seventies were inspiration for the costumes of the Yacht guests on Dryden Vos's ship. At one point, the yacht had a pool, and a team of artists was tasked with designing Star Wars swimwear and robes.
In order to create an immersive, 360 degree experience of the Sabacc game, crew used an Alexa camera and shot the 360 degree scene in 6 different passes, one tile at a time. In the end, the separate passes were stitched together into one seamless 360 experience users could have in Virtual Reality or on any 360 player.
Inspiration for Kessel's sulfurous yellow pools came from Dallol, Ethiopia. Due to the corrosive nature of their pools' gases, Lucasfilm and ILM were unable to visit the area, relying mainly on online research to capture its atmosphere.
A photo of the Lego set for the movie showed the Millenium Falcon's "Kessel Run", hinting the legendary event will be seen. On the set, the Falcon has a single point nose, and not the familiar dual-dagger front.
The speeder that Han and Qi'ra use in the "car chase" on Corellia has round thrusters on either end of the rear of the vehicle, which glow red. These are very similar in appearance to the taillights on 1960s models of the Ford Falcon automobile, thus providing a reference to Harrison Ford and the Millennium Falcon.
At the "immigration" area on Corellia, a stormtrooper tells someone to "move along, move along". This is a callback to Star Wars: Episode IV - A New Hope (1977), when Obi-wan Kenobi uses a Jedi mind trick to have a stormtrooper allow Luke's landspeeder through a checkpoint with the droids they were looking for.
Lando's yellow shirt and black cape combination was one of the early design concepts that never really changed. The design held its ground for over a year and would later influence the yellow accents seen aboard the Falcon.
The Sabacc table featured in Han and Lando's game had to be carefully designed: big enough to allow room for the puppeteers and the alien characters while small enough to keep the principals as close to camera as possible.
For shots on Corellia where the crew needed to see the actors drive the car on location, special effects rigged a "pod" to the front of the speeder so the stunt driver could drive from a hidden position.
American West artists Frederick Church and Albert Bierstadt served as inspiration when designing Savareen. Savareen also came to represent the end of the road for both Han Solo's and the audience's symbolic journey across America: Southern California, a place where the desert meets the sea, the end of the continent, and the birthplace of the modern film industry.
Original concepts of Chewbacca and other enslaved Wookiees on Mimban featured a partial Stormtrooper costume. This specialized armor and helmet would hide faces, allowing the creatures effects team to not have to build quite so many articulated Wookiee faces.
In this film, the Millennium Falcon has single-cannon guns mounted on its gun turrets. In Star Wars: Episode IV - A New Hope (1977), Han mentions that he has made some modifications on the Falcon himself. From Episode IV on, the Falcon's gun turrets have quad-barrel guns. This was evidently one of Han's modifications.
Lee Sandales, leader of the Set Decorating department, was inspired during a scouting trip in the Canary Islands to create a backstory for the Savarenians: they lived on the water and would harvest a kind of brightly colored shellfish. Evidence of a fishing lifestyle is hidden among all of the set decorations at the sight, including cloth and other materials stained by fabricated shellfish.
A speeder that appears in the background in Corellia is very well traveled. It first appeared in Star Wars: The Force Awakens in Abu Dhabi; it was then revamped and traveled to Iceland for Rogue One: A Star Wars Story, and was then revamped for a second time and shipped to the U.K. for this film.
Phoebe Waller-Bridge didn't realize L3-37 was a droid when she auditioned, and played her as a human. Although the casting directors asked her to try it again, except more "droid-y", they liked her original interpretation of the character and gave her the part.
L3-37's design was primarily driven by the fact that the droid would be played by a woman in a semi-practical suit. Later on, her femininity, rebuilding status, and status as an "older" droid would influence her final designs.
Jamie Costa, who portrayed Han Solo in the short film Han Solo: A Smuggler's Trade (2016), wanted to play Han Solo in this film. Interestingly enough, he posted a video of himself "auditioning" for the role on his YouTube channel.
In June 2017, Ron Howard was announced as the new director of the film. This is appropriate in that Howard previously appeared in American Graffiti (1973), a pre-Star Wars George Lucas film, which also starred Harrison Ford, the first actor to play Han Solo in feature film.
The cyborg serving girl seen in Dryden Vos' first scene was also present in Rogue One: A Star Wars Story (2016), but not seen very well although she's in the Visual Dictionary. Originally, there were two in the bar on Jedha, but they didn't make the final cut. Presumably, the costume got "recycled" for this movie.
Han's entry into the Imperial military mirrors James T. Kirk's entry into Starfleet in the new "Kelvin continuity" Star Trek: both grow up in an area where ships for the fleet are constructed, both enter their respective academies after an adolescence marked by petty crime, and both vow to become exceptional pilots. The similarities end there, as three years after his enlisting, Kirk becomes a starship Captain, while three years after his enlisting, Han has flunked out of the academy, and is relegated to being a "grunt" in the Imperial infantry.
During the kit-bashing process, as part of the swoop bike design, parts of Anakin's podracer were used on the concept model. When this model was scaled-up, these design details were also scaled up and can be seen on the finished vehicle.
Vandor represents the travel towards the new frontier typically seen within the Western genre. The Rocky Mountains, Chile, Patagonia, and the Dolomites in Italy served as inspiration for the rocky, snow-tipped mountains of the planet.
Quay Tolsite, the Pyke Syndicate's site administrator for the mines of Kessel, first appeared in Star Wars: The Clone Wars: Eminence (2013) [in which former Sith Lord Darth Maul recruited criminal factions like Black Sun, the Hutt Clan, and the Mandalorians of Death Watch to his "Shadow Collective."]
The on-set data wrangling team captured photo reference (still images), witness camera data (small video cameras), and set survey data along with other reference information. This data totaled approximately 40TB, which was be sent to Industrial Light & Magic, who used the data to assist in creating the visual effects shots for the movie.
Lando's "Hawaiian" shirt was inspired by a Ralph McQuarrie illustration: McQuarrie's spaceship-type skiff was transformed into a repeating pattern, with two suns and a body of water to create a tropical feel.
In Season 5 Episode 3 Of Arrested Development, Ron Howard narrates during a scene with Michael Cera. "He even inspired a certain move that would eventually appear 2 years later in a Han Solo origin picture" (11m:13s). In the scene Michael can be seen wearing a Darth Vader mask and performing a round house kick. This is a not so subtle Easter Egg and nod to himself since the Han Solo movie was directed by Ron Howard. The episode and movie were both released in May and was a nice treat to fans of both Arrested Development and the Star Wars franchise.
Screenwriter Jonathan Kasdan and First Assistant Director Toby Hefferman play Tag Greenley and Bink Otauna, who were featured in the Star Wars Expanded Universe (non-canon after Star Wars: Episode VII - The Force Awakens (2015)).
Han Solo's "secret fighting of pretend" with Chewbacca is most likely a reference to the Legends book "Ambush at Corellia", when Han is forced to fight a Selonian for the amusement of his evil twin cousin. Using his limited Selonian vocabulary, Han is able to communicate with her, and throws the fight.
In the original script for the Train Heist sequence, the rag-team boards the train from a herd of kod'yak's in the style of a classic western. Later, the scene needed to be cut in order to reduce the running time of the sequence.
In a deleted scene showing Pilot Solo's fall from grace to the Infantry at the Academy, he addresses the presiding officer as Moff. This is a title held by some Imperial Admirals in the Original Trilogy, but never spoken on-screen in those movies.
Charlie Cox lobbied for the title role and even had a screen test with the producers. However he was eventually turned down as they feared that his tendency of not keeping eye contact - a trait that was required for his portrayal of a blind man in Netflix's Daredevil - with the other characters weakens the character portrayal.
During the train robbery scene early in the movie, as Chewbacca is dangling over the side, he has to be hauled back in just before a large triangular rock would hit him. This mirrors a scene in Indiana Jones: The Last Crusade, in which Indiana Jones, played by original Han Solo Harrison Ford, is dangling from a tank and must recover before hitting a similarly placed rock.
In order to create an immersive, 360 degree experience of the Sabacc game, the crew used an Alexa camera and shot the 360 degree scene in 6 different passes, one tile at a time. In the end, the separate passes were stitched together into one seamless 360 experience users could have in Virtual Reality or on any 360 player.
As background vehicles in the Corellian factories, three electric tugs were built, incorporating some triangular flood defense barriers for their front bodywork, which were obtained from a government surplus supplier.
The visual effects crew measured and mapped the interior and exterior of Fawley Power Station and most of the surrounding site with sophisticated laser scanning equipment (Lidar). Around 200 acres in total!
The trivia items below may give away important plot points.
L3-37's memory is uploaded into the Millenium Falcon. In the radio adaptation of Star Wars: Episode V - The Empire Strikes Back (1980) C-3PO says that he's having difficulty talking to the Falcon's computer because she is "rather rude".
The rebels who appear at the end of the film have an alien fighter in their company with a black mask over his alien face, and two tubes coming out of his face. This is Benthic, later Saw Gerrera's second-in-command in Rogue One: A Star Wars Story (2016). The character also appeared in some post-Rogue One Marvel comics taking place after Star Wars: Episode IV - A New Hope (1977), in which he meets the main classic trilogy heroes.
Lando mentions Tobias Beckett killed Aurra Sing by pushing her to her death. Aurra Sing was a bounty hunter who first appeared in Star Wars: Episode I - The Phantom Menace (1999), observing the podracing. She appeared in Star Wars: The Clone Wars (2008) television show.
Darth Maul's cameo appearance at the end of the film was originally not meant to be in the film during the writing process, the person originally written as the head of the Crimson Dawn was generically referred to as "Boss", and was comprised of a list of many potential characters to fill that position, one of which was Darth Maul. Director Ron Howard lobbied hard for Darth Maul to fill that position, and it ended up in the final film with original Darth Maul actor Ray Park from Star Wars: Episode I - The Phantom Menace (1999) reprising the role, and Star Wars: The Clone Wars (2008) voice actor Sam Witwer also reprising his role to voice him.
At the end of the movie, Han wins the Millennium Falcon from Lando in a sabacc card game after Solo prevented Calrissian from using the cards hidden in the long sleeve of his shirt. This explains the reply of Han to Lando about winning the ship "fair and square", which he said in Star Wars: Episode V - The Empire Strikes Back (1980).
During the section when Val is discussing who she, Rio, and Tobias Beckett could have brought on for help instead of Han and Chewie, she mentions two parties. The Zan sisters are first, and they first appeared in the cantina on Mos Eisley. Bossk, who was the Trandoshan that first appeared aboard the star destroyer along with the other bounty hunters in Star Wars: Episode V - The Empire Strikes Back (1980), is also mentioned.
When Lando, Chewbacca, Qi'ra, and Han go for Calrissian's ship, Solo theorizes that it will be "a piece of junk". It's a nod to the famous reaction of Luke Skywalker's "What a piece of junk!" the first time he saw the Millennium Falcon in Star Wars: Episode IV - A New Hope (1977).
The appearance of the Millennium Falcon is clean and relatively unscathed until it crashes on planet Savareen after the escape via the Kessel Run. This is the condition in which it is first seen in Star Wars: Episode IV - A New Hope (1977).
During a suspenseful scene in the black hole cluster surrounding Kessel and the Maw, a Star Destroyer appears. This is likely a reference to the former canon, in which there was an Imperial installation inside the black hole cluster with Star Destroyers having "stood guard" over it for years.
When Han and Qi'ra are in line at customs on Correlia, trying to hide from Lady Proxima's henchmen, Han gives Qi'ra the set of golden dice that she, in turn, gives back to Han years later when they meet on Dryden Vos' yacht. These are the same famous dice seen in Star Wars: Episode IV - A New Hope (1977) and Star Wars: Episode VIII - The Last Jedi (2017).
Qi'ra utilizes a fictional martial art called "Teräs Käsi", other known practitioners include Darth Maul, Qi'ra's ally. "Teräs Käsi" is a martial art originally developed to be used against force-wielding opponents.
As of May 2018, this is the first chronological appearance of Darth Maul after the 2014 comic book limited series "Son of Dathomir" as this movie takes place several years before Darth Maul's death in Star Wars: Rebels (2014).
Each of the first two Star Wars Anthology films, Rogue One: A Star Wars Story (2016) and this movie, end with a ship en route to Tatooine. In "Rogue One", it is Leia's blockade runner, the Tantive IV. In this movie, it is Han and Chewbacca in the Millennium Falcon.
During the Kessel Run TIE chase, Han mentions that he picked up a move from his friend Needles, a street racer who crashed and died pulling a maneuver involving a spin-out. Needles is a reference to a character in Back to the Future Part II, who was involved in a street race with Marty McFly in 1985. Marty, depending on the reality, either participated in the street race, crashed into a Rolls Royce, and ruined his future as a rock star, or put his truck in reverse, allowing Needles to go ahead of Marty, where he nearly crashes into the Rolls Royce. Han puts the Falcon's landing gear down and drags the Falcon along a solid mass, which slows the ship, allowing the TIE Fighters to fly ahead and crash, while the Falcon eventually spins out and slide backwards.
(Also a spoiler for Avengers: Infinity War (2018) ). Second time in a Disney production released in 2018, where a red-faced villain who is assumed dead from an earlier movie is revealed to be still alive, with Red Skull for Avengers: Infinity War, and Darth Maul in this movie.
