Theatrical releases: May 25, 1977 (STAR WARS), May 21, 1980 (THE EMPIRE STRIKES BACK), May 25, 1983 (RETURN OF THE JEDI).
STAR WARS was passed up by a number of studios before 20th Century Fox finally providing a $10 million budget for the film.
The subtitle EPISODE IV: A NEW HOPE didn't appear in the original title sequence for STAR WARS. It first appeared in the remastered version which Lucas produced in 1997.
David Prowse, who plays Darth Vader, allegedly had no idea during filming that his vocal parts would be replaced in post-production by the voice of James Earl Jones.
Jabba The Hutt was portrayed by a human actor whose dialogue was in English in the original version of STAR WARS, but the scene was cut from the final print of the film. George Lucas restored it, and replaced the actor with a CGI version of Jabba in the 1997 remastered edition of the film.
STAR WARS was an original selection to the Library of Congress National Film Registry in 1989.
George Lucas altered the dialogue at the end of THE EMPIRE STRIKES BACK in post-production so that he could prevent the surprise conclusion from leaking to the press. On set Darth Vader actor David Prowse said "Obi-Wan Kenobi is your father" to Luke. In the finished film Vader says "I am your father."
John Ratzenberger, "Cliff" from TV's CHEERS, had a small part as Major Derlin in THE EMPIRE STRIKES BACK.
The working title for RETURN OF THE JEDI was REVENGE OF THE JEDI. The production was kept under wraps via the cast and crew, who informed anyone who asked that they were shooting a movie called "Blue Harvest."
The Ewoks weren't in the original script of RETURN OF THE JEDI, which contained a planet inhabited by Wookies. This idea was discarded when it was decided a more primitive race was needed to inhabit the planet, and the Ewoks were born.
George Lucas revisited the trilogy in the late 1990s to make a series of amendments to the special effects, largely caused by the advancements in CGI technology that weren't available to him when the original films were conceived.
The 2004 release of the STAR WARS TRILOGY DVD boxed set saw further special effects work added at Lucas's behest.
The videocassettes of the trilogy were the first to be digitally mastered in THX.
The THX process was developed by LucasFilm and named after George Lucas's early science fiction film THX-1138 (1971).
