Trivia: The film's screen tests were spoofed in a 1997 episode of "Saturday Night Live," which included Kevin Spacey playing Christopher Walken auditioning for the role of Han Solo. Walken really was considered for that role before Harrison Ford was chosen. Spacey also played Walter Matthau auditioning for Obi-Wan Kenobi and Jack Lemmon auditioning for Chewbacca.
Trivia: The sound that is made when they power up the Death Star's hyperlaser to destroy Alderaan is the same sound used in the THX Certifier on many DVDs.
Trivia: In the Death Star scenes (yes, all of them), whenever the Imperials walk, you can hear their footsteps. But when Tarkin walks, you can't hear him. This is because Peter Cushing (Tarkin) found his Imperial boots so uncomfortable, he didn't wear them. He wore carpet slippers, so you can't hear him. The only shots in which he can be seen wearing boots are shots in which he remains stationary.
Trivia: According to the documentary "Empire of Dreams," as well as interviews on the "Revenge of the Sith" DVD, George Lucas originally wrote the "Star Wars" trilogy as one long serial titled The Tragedy of Darth Vader, which ran about 200 pages. He then broke it into three separate stories, and focused solely on the first part, which became "Star Wars."
Trivia: The heavy rifle used by Chewie in the Death Star is a German WW2 MG 34.
Trivia: When the film was first released in movie theatres in 1977, there was no 'Episode IV: A New Hope' on the opening crawl, because the producers said that people would be completely confused by it as there were no other 'Star Wars' films at the time. It was only after the film became a success that George Lucas was able to put the words back on.
