The shots where Luke uses his Jedi powers to retrieve his lightsaber from a distance were achieved by having Mark Hamill throw the lightsaber away and then running the film in reverse.
In order to avoid sharing creative rights, George Lucas decided to avoid using a major studio to finance this film. Instead, he bankrolled the $18 million production himself, using a combination of his profits from Star Wars: Episode IV - A New Hope (1977) and a bank loan. Although the move was risky, it paid off several times over. Lucas recovered his investment within three months of the film's release. He then showed gratitude far beyond the Hollywood norm, by sharing the profits with his employees (nearly $5 million in bonuses).
Mark Hamill had to bang his head 16 times on the ceiling of Yoda's hut before Irvin Kershner was satisfied.
Carrie Fisher stood on a box for many of her scenes with Harrison Ford in order to make up for the height difference and have her appear in the frame with him. Carrie Fisher (5'1) was a foot shorter than Harrison Ford (6'1).
When shooting on location in Finse, Norway, a fierce snow storm hit the hotel where the cast and crew were staying. This would have normally halted filming, but director Irvin Kershner thought these weather conditions were an excellent opportunity to film the scene where Luke wanders through the snow after escaping the Wampa cave. He did this by sending Mark Hamill outside into the cold, while he and the cameraman stayed and filmed inside the hotel's front hall.
To preserve the dramatic opening of the Star Wars movies, George Lucas insisted on moving all the credits to the end of the film. However, although the Writers' Guild and Directors' Guild had begrudgingly allowed this on Star Wars: Episode IV - A New Hope (1977) (because that film wasn't expected to be very successful), they resented the trend being continued on this film. First they tried to pull Empire from release, but were unsuccessful. They then fined Lucas heavily, and tried to fine Irvin Kershner, but Lucas paid all the fines himself (nearly $250,000). Lucas then bitterly dropped his membership in the Writers' Guild, Directors' Guild, and the Motion Picture Association of America, a move that has hindered his hiring choices on later films (see also Star Wars: Episode VI - Return of the Jedi (1983) and Star Wars: Episode III - Revenge of the Sith (2005)).
With the exception of being sucked out of a Cloud City window, Mark Hamill did all of his own stunts.
George Lucas was so impressed by Frank Oz's performance as Yoda that he spent thousands of dollars on an advertising campaign to try and get him an Oscar nomination for Best Supporting Actor. Lucas's campaign ultimately failed because it was felt that a puppeteer wasn't an actor. Lucas felt this wasn't fair to Oz, who honestly didn't care.
During the filming of the Battle of Hoth, the Echo Base troops were actually Norwegian mountain-rescue skiers. In exchange for participation in the film, Lucasfilm made a donation to the Norwegian Red Cross
When Mark Hamill was having trouble with the Dagobah scenes with Yoda, Frank Oz brought in Miss Piggy to make him laugh.
One of George Lucas' goals in doing a Star Wars sequel was to become financially independent from Hollywood, and he succeeded in this goal.
Yoda's iconic manner of speech has the parts of speech in Object Subject Verb order. Very few languages on Earth use this and most are based in the Amazon river basin.
Jim Henson, a friend of George Lucas, was offered the role of Yoda. Henson turned it down, as he was busy with The Great Muppet Caper (1981). He recommended Frank Oz for the role.
In the DVD commentary, Carrie Fisher relates that during some of the London filming, she stayed a house rented from Eric Idle. Idle and the Pythons were filming Life of Brian (1979) at the time. One evening, Idle had a small party, including Harrison Ford and The Rolling Stones, and served a potent liquor (which the Pythons had been distributing to extras on their film, to help boost morale) that he referred to as "Tunisian Table Cleaner". They stayed up most of the night drinking and having fun. The first scenes shot the next day were the arrival at Cloud City, which she says helps explain why she and Ford were so happy in those scenes. Idle is said to be pleased that he had a small hand in how the finished film turned out.
Originally in the asteroid scene, one of the asteroids was actually a shoe. The rumor is that George Lucas asked the SFX people to redo the scene so many times that they got annoyed and one of them threw in his or her shoe. Later remastered versions have corrected this.
Darth Vader sarcastically inviting Han to dinner is the only time in any of the "Star Wars" films that Vader speaks directly to Han.
In each Star Wars film, the line "I have a bad feeling about this" is spoken by one of the characters. In this film, Leia says it.
George Lucas initially called this the worst Star Wars film, and apologized for its existence. He changed his mind after he found out some people believed it was the best Star Wars film.
The sound of Darth Vader's shuttle door opening is reportedly a recording of a whole block of Alcatraz cell doors slamming shut.
An oft-quoted myth is that the Wampa attack on Luke was devised to explain the actual scars on Mark Hamill's face because he had been involved in a car crash and had to have reconstructive surgery. Hamill did indeed survive a serious car crash in January 1977 but did not have any visible scars by the time Empire began filming over two years later.
In an early outtake, when Vader entered the Hoth base, he tripped over a cable and fell down face-first.
The scenes where R2-D2 is submerged in the mud pool were shot in George Lucas' unfinished swimming pool. Most of the crew were hidden under the water and the entire sequence was shot by George Lucas himself.
In an interview with Cinescape magazine, director Irvin Kershner said he had no interest in films with special effects. However, he was won over by George Lucas, although Kershner was determined to make the film more about characterizations than hardware. Kershner spent several months working on the script, pushing the writers into humanizing the characters more (something that Lucas has often been criticized for failing to do).
George Lucas decided that a battle on an ice planet was necessary because he felt that it was easy to "cheat" in space, because the background was black and you could hide errors easily. With a white background, the effects crews would have to work much harder, and the effects would be much more impressive.
Another of the asteroids is actually a potato. It appears just as the Millennium Falcon first enters the field. Two asteroids travel from the top left to the bottom right corner of the screen. Just after the second asteroid leaves the screen a third one appears in the top left corner. This is the potato.
During principal photography it remained unclear if Sir Alec Guinness would return as Obi Wan Kenobi as he had just had an eye operation at the time. He finally did agree and worked just one day on the film (Wednesday, September 5, 1979). He arrived at 8.30am and completed his scenes by 1pm, for which he was paid a quarter of a percentage point of the film's gross which was worth millions of dollars.
Of the original 6, this is the Star Wars film that George Lucas had the least involvement with. It is considered to be the best film in the saga.
The entire Millennium Falcon was built life size for the first and only time for this installment (only half of the spacecraft was constructed for Star Wars: Episode IV - A New Hope (1977) and just part of it was used for the deleted sandstorm scene in Star Wars: Episode VI - Return of the Jedi (1983)). It measured 65 feet in diameter and 16 feet in height with a mandible giving it an overall length of 80 feet. The Falcon's weight was 23 tons.
Mark Hamill's wife gave birth to their first son (Nathan Hamill) early one morning, and Mark went straight from the hospital to shooting. This was the day they filmed the shots of Luke climbing out of his snowspeeder before it is crushed by the Imperial walker, and Hamill broke his thumb during the stunt.
The film premiered at a limited number of theaters, and those all in large metropolitan areas because it was first released only on 70 mm film, for which only the largest and most prosperous film theaters had projectors. It was many weeks later that the film was released on standard 35 mm film for other film theaters in North America and around the world.
Darth Vader's meditation chamber is said to be a hyperbaric chamber which charges the interior air to greater than one atmospheric pressure, thus allowing him to remove his helmet and breathe normally for limited periods of time. This was not as originally presented in the film, however, which featured an additional breathing mask for Vader in the chamber, which was notoriously shown for only a split second and never made it into the official continuity.
Irvin Kershner initially turned down the opportunity to direct the film as he felt that it would be too difficult to top the success of Star Wars: Episode IV - A New Hope (1977). He took the job when his agent convinced him that he shouldn't pass on the opportunity to make a sequel to one of the most popular movies in history.
For the 2004 DVD release, the scene with Darth Vader and the Emperor was altered with Ian McDiarmid now playing the Emperor, as he does in the rest of the series (the original version of the scene had the Emperor played by a hooded old woman with superimposed chimpanzee eyes and was voiced by Clive Revill). The dialogue for the new version was expanded and completely re-recorded by Ian McDiarmid and James Earl Jones.
Carrie Fisher traveled to the filming location of Finse, Norway, even though she was not scheduled to take part in any outdoor scenes.
As Yoda and Obi-Wan urge Luke to stay on Dagobah to finish his training, Luke pulls a snake from his spaceship. Irvin Kershner assured Mark Hamill that the snake was harmless, though it did bite him during one take.
The Dagobah set needed to be elevated to give Frank Oz and three other puppeteers room to control the Yoda puppet from below. For proper interaction, Mark Hamill was given an earpiece so he could hear Oz doing Yoda's voice. On numerous occasions, Irvin Kershner would give a direction to Yoda by mistake and Oz would have to remind him who to talk to.
Han Solo's use of his mount's entrails to keep Luke warm is actually an American Indian trick. According to legend, a hunter named Hugh Glass had killed a bear despite being mauled severely, in the American frontier. He was abandoned by his fellow frontiermen, and had to crawl hundreds of miles to safety. On the way he became trapped by a sudden blizzard. He cut open a horse's stomach and climbed inside and stayed warm and safe until the storm had subsided. This event is dramatized in The Revenant (2015), starring Leonardo DiCaprio.
The carbon freezing chamber is the only time in the original trilogy that Darth Vader and C3PO can be seen on screen together.
One of the first ideas for Lando Calrissian was to have him as a clone who survived the Clone Wars who leads legions of clones on a planet they settled on. Another idea had Lando as the descendant of survivors of the Clone Wars, born into a family who reproduced solely by cloning. Originally, his name was "Lando Kadar".
George Lucas had originally planned to only Executive Produce and finance the film, leaving the directorial duties in the hands of Irvin Kershner and day-to-day producing duties to Gary Kurtz. Directing the original Star Wars: Episode IV - A New Hope (1977) had left Lucas exhausted and sick, and he had intended to take time off to start to focus on the expansion of the Lucasfilm company and spending more time with his then-wife Marcia Lucas, so that they could start a family and finish construction on Skywalker Ranch. However, when production on this film ran overbudget and behind schedule, Lucas had to step in and take a more hands-on role, going on location to oversee filming and even directing portions of the film. A disastrous rough cut of the film proved incoherent during screenings, and facing the possibility of financial ruin, Lucas then re-edited the film himself with even worse results. Extensive reshoots and further post-production effects work put enormous strain on his health, his marriage, and his relationships with Kershner and Kurtz. Though the film proved an enormous critical and commercial success, Lucas would never work with Kurtz again, and his marriage dissolved a couple of years later.
Director Irvin Kershner decided that for this movie, members of the Rebel Alliance would speak with American accents, while the Imperial Officers would speak with British accents, to make the story analogous to the American Revolution. However, most of the supporting actors that appeared as Rebel personnel on Hoth were in fact British actors. Consequently, Kershner had to re-dub several of the scenes taking place at the Hoth rebel base with American voices in post production.
Lighting for the special effects scenes in space was so strong that several models melted.
The blizzard in the Hoth scenes is a real blizzard - no effects were used. Harrison Ford could not arrive at the filming location via the regular train route as it was closed due to the bad weather - so he went to the site on a snow plow.
After the various increases in budget, the film became one of the most expensive of its day and after the bank threatened to pull his loan, George Lucas was forced to approach 20th Century Fox. Lucas made a deal with the studio to secure the loan in exchange for paying the studio more money, but without the loss of his sequel and merchandising rights. After the film's box office success, unhappiness at the studio over the deal's generosity to Lucas caused studio president Alan Ladd Jr. to quit. The departure of his longtime ally caused Lucas to take Raiders of the Lost Ark (1981) to Paramount Pictures.
The Imperial AT-AT walkers were all animated through traditional stop-motion techniques, except for the scenes where they fall (e.g. the walker which is "tripped up" by cables and falls on its head, or the one that Luke throws a thermal detonator into, which falls on its side). These were filmed in real-time on high-speed cameras with precision-timed mini-pyrotechnic charges.
After an extra fell sick, Jeremy Bulloch (Boba Fett) was called in as a replacement to the Imperial Guard who escorts Princess Leia and pulls her into the elevator after she screams "Luke! It's a trap!". He's the same Imperial Guard who is captured by Lando Calrissian's men.
The sound of Vader's helmet being lowered onto his body was the sound of someone putting their hand over a vacuum tube while it was still sucking in dust.
There seems to be many stories behind Alec Guinness and his role as Obi-Wan Kenobi. In George Lucas's original treatment (when it was ALL one story instead of a trilogy), Obi-Wan lives throughout the whole story (a fact confirmed by Lucas in the DVD commentary). However, Obi-Wan ends up getting killed off in the first film Star Wars: Episode IV - A New Hope (1977). There are many stories as to why Lucas changed it. There are some stories that either Guinness demanded that Obi-Wan was killed off so he wouldn't have to appear in any sequels or Lucas did it on his own much to the bitterness of Guinness. In the New Hope DVD Commentary, Lucas says that he felt it was a waste of Guinness's talents to have him stand beside Leia in the control room during the Death Star battle (as it was scripted) and too outlandish to have the elderly Obi-Wan join the dogfight. So he killed off Obi-Wan in order to spur Luke on to going into Jedi training and defeat the Empire. In any event, when it came time to make Episode V: The Empire Strikes Back, in which Luke begins his training, Lucas drew from the "ugly creature with mystical powers" mythological archetype (as he did when creating Star Wars) and created Yoda as Luke's new Jedi master. Kenobi still makes appearances in the sequels as a Force spirit.
One of the bounty hunters Darth Vader hires to find Han Solo is IG-88. He is one of a series of IG-86 Sentinel Droids. Another can be seen in the Cloud City. The shell of this second droid can be seen in the smelting room next to a furnace where C-3PO is found by Chewbacca.
Boba Fett is never referred to by name in the film. He is always referred to as "the bounty hunter" by other characters. However, a deleted scene included in the blu-ray set shows Leia tending to Luke's wounds and says "a bounty hunter named Boba Fett" has taken Han Solo.
The only Star Wars Original Trilogy film that does not take place on the desert planet Tatooine (although it is mentioned by name at the end of the film). Tatooine does appear, however, in Episodes I, II, and III, making it the only planet that appears five times in the entire saga.
The lightsaber fight scenes set in the carbon freezing chamber tend to focus on Luke. This is because during many of the shots, Bob Anderson (Vader's fight double) was not wearing the Darth Vader helmet, as it made it difficult for him to breathe.
The AT-ATs were inspired by the walking machines in H.G. Wells's "War of the Worlds" and their appearance was based on gantry cranes which are used in most shipping ports in the USA. Walking patterns of elephants were studied to make the movements seem as realistic as possible.
Principal photography lasted over 180 days, the longest shoot of any of the "Star Wars" movies.
Boba Fett's action figure was originally to have had a rocket-firing mechanism, but after a child choked to death on a similar toy, the Colonial Viper from Battlestar Galactica (1978), Kenner dropped the mechanism and made the rocket stationary. A trace of the rocket launcher survived to the completed toy, however, as there is a rectangular area on the backpack in which the rocket launcher would have been embedded. The version with the mechanism is now considered the longest-running unobtainable action figure; contrary to popular belief, it was never sold to the public.
Luke is separated from most of the main characters for the majority of the film. In fact, the only scene with all of the main Rebel characters is the hospital bed scene.
The only way to get to the set in the midst of a blizzard during filming in Norway was on a snowplow train, which had a giant auger on the front, pushing through the snow to deliver the actors to the set. The weather conditions were so severe that the crew put the camera in the back door of the hotel the cast and crew were staying and shot from out the door, 12 feet from the hotel out in the blizzard.
Luke is upside-down at the beginning (Wampa cave), in the middle (training on Dagobah), and at the end (below Cloud City). He uses the Force each time.
When Jeremy Bulloch went in for the role of Boba Fett and donned the costume, he figured that the Wookie scalp which adorned his shoulder was some sort of hairpiece and he tried to put it under his helmet.
In the medical bay where Luke is recovering, when he folds his hands behind his head and contorts his mouth after being kissed by Leia, he is imitating Chewbacca on board the Millennium Falcon in Star Wars: Episode IV - A New Hope (1977) after Han Solo warns C-3P0 to let Chewbacca win the game.
During the same year Star Wars: Episode V - The Empire Strikes Back (1980) was released, R2-D2 and C-3PO appeared in 2 episodes of Sesame Street (1969) Season 11, as well as in an episode dedicated to Star Wars in The Muppet Show (1976), alongside Luke Skywalker (Mark Hamill) and Chewbacca in the latter. This was to celebrate the fact that Puppeteer Frank Oz would be starring in the new Star Wars film.
The bounty hunter dressed all in white is named Dengar. His backstory is that he was once a fierce rival of Han Solo's, and was badly beaten by him. He vowed revenge and has been hunting Solo for some time.
When Luke is confronted by the phantom Darth Vader in the cave, in the original theatrical release, the "FAKE" Darth Vader has an alternate sound effect of his iconic "Breathing" and his lightsaber is colored in a more ORANGE tone and not his traditional RED. This was to give the audience a hint that Luke was not fighting the real Darth Vader. However, with the re-release and special editions of Empire Strikes Back that have come out since, cave Vader's lightsaber has been given a RED color to match the real Vader, though the alternate sound of his breathing has been left unaltered.
Was filmed at the same studios as Stanley Kubrick's The Shining (1980). Author Stephen King visited the set, and many aspects of this film affected King's later work. Irvin Kershner was nicknamed "Kersh" on the set. King's novel It (1990) features a character named Mrs. Kersh, who sounds like Yoda.
The scene where Solo was hit by the toolbox as well as hitting the control panels were improvised on the set. At first, the crew were afraid of shooting it, but Irvin Kershner finally persuaded them to do so, saying "Come on, that's fun. Let's do it!"
In certain shots of the Rebel hangar, the filmmakers enlisted children as extras. The reason for this was that the actors' short stature would make the hangar appear larger than it actually was.
Months prior to the film's release, John Williams was named Conductor of the Boston Pops Orchestra. During Williams first televised performance with the Orchestra on PBS's Evening At Pops, he publicly premiered some of the new scoring pieces he composed for the movie.
Yoda's appearance was originally designed by British makeup artist Stuart Freeborn, who based Yoda's face partly on his own and partly on Albert Einstein's, as his eyes are supposedly inspired by the latter. Yoda is voiced by Frank Oz. In the original Star Wars trilogy, he is realized as a puppet (controlled by Oz).
The Yoda puppet was made of a less than optimal material, resulting in it being quite a bit heavier than what Frank Oz was used to from his time with the Muppets. The strain put on his arms meant the scenes had to be shot on a quite erratic schedule.
The concept design for Cloud City was originally created for Star Wars: Episode IV - A New Hope (1977) (as a floating Imperial prison), but was never used. The design was recycled for use in this film.
The space suit worn by the bounty hunter Bossk was previously used in The Tenth Planet, a Doctor Who serial.
Second unit director John Barry joined the film after quitting Saturn 3 (1980) following a dispute with that film's star, Kirk Douglas). Barry died of meningitis during production, after collapsing on set.
More scenes of the AT-ST Imperial "chicken walkers" were filmed, but George Lucas decided that the larger AT-ATs were more menacing and impressive. He later realized that the AT-STs would work better in close quarters, which led to using them extensively in the forest battle in Star Wars: Episode VI - Return of the Jedi (1983).
The sound of the Tauntauns was produced by recording the sound of an Asian sea otter named Moda.
An earlier draft had Luke's reason for not leaving with Lando & Chewie at the end being that his Jedi training was more important. Believing that this would make Luke seem less sympathetic, Irvin Kershner had it changed to where Luke was still recovering from his injuries and that rescuing Han would be his first priority once he was fully recovered.
In the Hoth command center, Han makes a reference to "That bounty hunter we ran into on Ord Mandell". An audio drama based on this, "Rebel Mission to Ord Mandell" was released in 1983 as an NPR radio drama, and later on 33 1/3 LP. It featured the voices of many of the original cast.
Shortly after release, Darth Vader's name was changed to Lord Fener in Italy. This is because the word 'vader' in italian sounds like 'toilet'.
The sound of Darth Vader's meditation chamber was actually the sound of a generator at an air force base the crew visited.
For the Dagobah scenes, Mark Hamill was the only one listed on the callsheets as an actor. Everyone else was listed as crew.
The scene in the Cloud City apartment where Han Solo enters to tell Princess Leia that the repairs on the Millennium Falcon are almost complete played out differently in the finished film than it did in the original script. There, Han Solo (Harrison Ford) is lounging around in the apartment when Princess Leia (Carrie Fisher) enters, having changed from the white combat clothes she wore on Hoth to the brown dress and having her hair done up differently. In surprised reaction to how she's dressed, Solo attempts to flatter her ("You look beautiful. You should wear girls clothes all the time.") and Leia teases him by mentioning Luke; the scene ended with them sharing a kiss. The film was originally shot this way, but director Irvin Kershner felt it wasn't coming out right, so he re-shot it to appear as it does in the finished film. Excerpts of how the scene was originally filmed can now be seen on the special edition DVD.
Jason Wingreen was the uncredited voice of Boba Fett, a fact not confirmed until 2000. Wingreen had originally auditioned to voice Yoda. In a 2010 interview, Wingreen noted his lines were completed in only ten minutes. However, Wingreen complained he never received residuals for the role, even though audio of his voice was used for talking Boba Fett toys and collectibles. As a result, Wingreen noted he had no love for George Lucas.
The film was such a success financially, it recovered its $18 million budget within three months of its release.
Darth Vader's costume was more detailed in this film, including the flashing red lights on his chest box. A new Millennium Falcon (32-inches long) was built for this film and has two additional landing gear boxes on its underside. As a result, the original Star Wars: Episode IV - A New Hope (1977) model (5-foot long) was modified and given the extra landing gear bays and was used for all FX scenes of the Falcon in a landed position.
Contrary to popular opinion, Han's line "I know" was not improvised on the spot. Harrison Ford and Irvin Kershner had met before filming the scene and decided on the new dialogue. Carrie Fisher was upset that she had not been part of the process, and Lawrence Kasdan was disappointed that his dialogue had been changed, feeling it had been some of his best writing.
Billy Dee Williams had previously auditioned for the role of Han Solo in Star Wars: Episode IV - A New Hope (1977). He finally landed the role of his old pal Lando three years later.
The sound of R2-D2 moving was produced by recording the sound of a car window motor in operation.
Director Harley Cokeliss, who was a friend of Frank Oz having worked with him on The Muppet Show (1976), visited the set towards the end of filming when the production team were struggling to get everything in the can before they ran over schedule. Cokeliss was hired on the spot as an additional director and is credited as one of the Second Unit Directors.
The chasm deep in the heart of Bespin in which Luke and Vader have their lightsaber duel was created using a matte painting. The same strategy was used in the original film in the scene where Luke and Leia blast Stormtroopers across an inactive bridge.
Ben Burtt recorded sounds of people in snow while visiting his family in upstate New York, which were used for the Hoth scenes.
Denis Lawson plays Wedge Antilles. Wedge was not originally scripted to appear in this film, but intense fan interest prompted George Lucas to include him. See also Star Wars: Episode VI - Return of the Jedi (1983).
The Millennium Falcon was constructed in a hangar at Pembroke Docks where great flying boats were made in the 1930s. It was brought to Elstree studios, London in sixteen interlocking sections by a convoy of trucks. After reassembly, the Falcon was floated into position on the then brand new Star Wars stage by means of compressed air pads similar to those used on hovercraft.
The book "Star Wars: The Annotated Screenplays" reveals that, when the script for this movie was first written, the idea of it being "Episode V" of a 9 part serial had not yet been established, and it was at one point called Episode II.
This was the first movie in which there was a double for Darth Vader. In the commentary, Peter Diamond said that this was done because of the presence of bigger fights.
When escaping the asteroid field a TIE fighter strikes an asteroid. As the asteroid travels down and to the right off screen, the pilot can be seen traveling down and to the left doing back flips as he travels off screen.
Most of the extras in the snowy battle scenes on the ice planet Hoth (shot at Finse, Norway) were Norwegians. One of the extras - Tom Egeland - would later become the chief news editor for one of Norway's largest TV networks, as well as a critically acclaimed mystery writer. Another - Arve Juritzen - would become one of Norway's best known TV-personalities (hosting eg. Vil du bli millionær? (2000), Big Brother Norge (2001)).
Harold Weed, an ILM staffer who assisted in designing the Wampa costume for the Special Edition, was cast as the Wampa for the film after he was used as the model for the costume. As he is 6 feet tall, the ice cave set for the re shoots was built with a height of 4 1/2 to 5 feet to create the illusion of the Wampa being closer to 8 or 9 feet in height.
Several crates of simulated snow as seen on the Hoth Hangar set were taken along to Finse, Norway, just in case there was not enough real snow lying about.
Yaphet Kotto was offered the role of Lando Calrissian, but turned it down because he believed he would be killed off and it would be difficult for him to find work after that.
For the Special Edition, Vader's "Bring my shuttle" line has been replaced with, "Alert my Star Destroyer to prepare for my arrival." Sound designer Ben Burtt claimed this is actually a line performed by James Earl Jones that was recorded for use in Star Wars: Episode IV - A New Hope (1977), but never used; however, not only does the voice sound nothing like James Earl Jones, but the famous Imperial ships were NOT called Star Destroyers in the original film, but "star cruisers" -- even the novelization calls them such, so this one line would be an odd bit of discontinuity if Burtt's claims were true.
The incident where R2-D2 accidentally electrocutes himself by mistaking a power outlet for a computer terminal was taken from the novelization for Star Wars: Episode IV - A New Hope (1977).
Gary Kurtz was initially reluctant for George Lucas to hand over the reins to another director. It was only because Lucas trusted Irvin Kershner, his former teacher at USC, that Kurtz agreed to the move.
Eight R2-D2s were used in the making of Star Wars: Episode V - The Empire Strikes Back (1980). Kenny Baker used two that were lighter and more comfortable than the ones from Star Wars: Episode IV - A New Hope (1977). Three were dummy versions which could be damaged and another three were remote controlled.
The only Star Wars film not to gross $300 million domestically, not adjusting for inflation. When adjusting for inflation, it is actually the second highest grossing Star Wars film domestically with an adjusted gross of over $780 million as of 2014, and is the 12th highest grossing film of all time in North America.
A scene where Darth Vader's shuttle lands in his Star Destroyer's landing bay, after his light saber fight with Luke, was added to the Special Edition. This was actually an unused scene from Star Wars: Episode VI - Return of the Jedi (1983)
When Han Solo tricked Darth Vader by landing the Falcon on his ship, Vader's crewman says they couldn't have used a "cloaking device" since the ship was small. "Cloaking device" was a term invented on Star Trek (1966).
One of only two Star Wars films without English subtitles to translate alien languages, the other being Star Wars: Episode III - Revenge of the Sith (2005).
WILHELM SCREAM: Heard twice in the film. Once during the battle on Hoth as a rebel soldier and his laser gun dish explodes. And right before Han is going to frozen in the carbonite. As Chewie, in a fit of rage, throws a stormtrooper off the ledge (barely audible).
According to the Dutch director Paul Verhoeven at a Q&A session in Helsinki, Finland during the 2012 Night Visions Film Festival, he was under consideration to direct The Empire Strikes Back, based on his work on his film -Soldier of Orange (1977)_. He was invited for a meeting with the producers and brought with him his newest film Spetters (1980), that he was proud of and wanted to screen for the producers. After the screening he never heard from them again and the film would eventually be directed by Irvin Kershner.
Most of the rebel ground troops in the Hoth battle were Norwegian extras. Because they didn't speak any English, second unit director Peter MacDonald had to "act out" what he wanted them to do, by pointing in the direction of the "enemy" (which wasn't visible during shooting) and demonstrating the recoil motion he wanted for the blaster rifles.
Harrison Ford was not expected to take part in the location filming in Norway which represented the scenes based on the ice planet of Hoth, so his costume was made for the stage and consequently not very well insulated. At the last minute, weather conditions were such that the schedule needed to be changed, and it was decided to shoot his scenes in Norway instead.
Further scenes with the Wampa were shot, and later cut. R2-D2 encountered one within the Rebel base, where it was killed by troopers. Later, the beasts were lured into a prison within the complex. In the completed film, a medical droid is seen examining the wounds of a tauntaun killed by a Wampa, and Princess Leia mentions the "creatures" while discussing the Imperial probe droid. A scene filmed but cut had Han, Leia and C-3PO running through a corridor. Han went to take a short-cut through a door with a sign on it, but Leia warned him "that's where those creatures are kept". They run off, but not before C-3PO rips off the sign, hoping that the stormtroopers will enter the room. They did. A few seconds of this last scene can be seen in the theatrical trailer on the DVD.
Veteran screenwriter and frequent Howard Hawks collaborator Leigh Brackett succumbed to cancer shortly after completing her first draft of the script of the film. On the strength of two unsold scripts (The Bodyguard (1992) and Continental Divide (1981)) Steven Spielberg got novice author Lawrence Kasdan a twenty minute meeting with George Lucas, who engaged the young screenwriter to complete the script.
Director Irvin Kershner provided the voice of Darth Vader himself in the temporary mix of the film, before James Earl Jones recorded the final version.
Production difficulties meant that the film went over budget by more than $10 million.
Part of the reason for creating Lando as a black character was that George Lucas had considered making Han Solo a black man early in his development of Star Wars: Episode IV - A New Hope (1977).
