Random Trivia For This Title:
- The only [Star Wars] film that does not take place on the desert planet Tatooine (although it is mentioned by name at the end of the film).
- 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.
- 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".
- On Hoth, General Rieekan says, "Send Rogues 10 and 11 to sector 38," a veiled reference to THX 1138.
- Security surrounding this movie was so intense that George Lucas had regular reports about "leaks" from actors. George Lucas was so determined that the ending be kept secret that he had David Prowse (Darth Vader) say "Obi-Wan killed your father", and dubbed it later to be "I am your father". In fact, only six people knew about the ending: George Lucas, director Irvin Kershner, writers Leigh Brackett and Lawrence Kasdan, Mark Hamill, and James Earl Jones.
- In the famous scene right when Han is frozen, he replies "I know" to her "I love you". Originally, the scene was shot with Han replying "I love you, too", however, Harrison Ford didn't think that it fit Han's personality. George Lucas agreed, and Ford ad-libbed his now famous line.
- 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.
- In the asteroid scene, one of the asteroids is 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 their shoe. 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.
- The carbon freezing chamber is the only time in the original trilogy that Darth Vader and C3PO are in the same scene together.
- When shooting on location in Norway, a fierce snow storm hit the hotel where 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.
