Trivia: Carrie Fisher has stated that her scenes as Princess Leia with Grand Moff Tarkin - Peter Cushing - were not easy to play. During filming, Peter, as Tarkin, would speak demeaningly to her. When the cameras stopped, he would converse with her in such a gentlemanly fashion that she found it hard to play her part against him when filming commenced again.Allister Cooper, 2011
Trivia: During Han's conversation with Greedo, the line "Even I get boarded sometimes - do you think I had a choice?" was lifted from his conversation with Jabba that didn't make it into the original release. If you pay attention you'll notice that when he says that line the camera is on his hand unsnapping the holster of his gun, not on his face. When the Jabba scene was put into the Special Edition they left the line in both scenes, making the Jabba scene repetitive.
Trivia: When George Lucas was mixing the American Graffiti soundtrack, he numbered the reels of film starting with an R and numbered the dialog starting with a D. Sound designer Walter Murch asked George for Reel 2, Dialog 2 by saying "R2D2". George liked the way that sounded so much he integrated that into Star Wars.
Trivia: While filming the desert scenes, Anthony Daniels' C-3PO costume kept falling apart, especially the legs. In many of the close-ups, Daniels was in costume only from the waist up. Notice as Luke and Obi-Wan pick up the damaged droid following the Sand people attack - the film cuts to the next scene with an upward vertical wipe, to avoid having to show his legs.
Trivia: George Lucas decided to release "Star Wars" in May 1977 instead of the start of the summer movie season (in the 1970s, it was a new concept as the result of the success of "Jaws" in 1975) in June because he wanted kids still in school to talk about it so as to spread word-of-mouth.Onesimos
Trivia: The reason why C-3PO lets R2-D2 go in front of him as they enter the Skywalker's residence right after being purchased from the Jawas, is because the set guy operating R2-D2 by radio control kept on hitting C-3PO from behind and pushing him down the stairs, so in the final shot, C-3PO suddenly steps to the side, waves R2-D2 past, and the shot cuts out right before R2-D2 goes flying down the stairs.
