1. When production began Star Wars was known as "The Adventures Of Luke Starkiller, As Taken From The Journal Of The Whills, Saga 1: The Star Wars". Snappy title huh?
2. In George Lucas' original draft the opening lines read "A long, long time ago, in the not-too-distant future…" - makes about as much sense as Jar Jar Binks!
3. Wedge Antilles is Obi-Wan Kenobi's uncle! Well not actually, but Denis Lawson, who plays Wedge Antilles, is the uncle of Ewan McGregor, who plays Obi-Wan Kenobi in the prequels.
4. It's well documented that Harrison Ford was nowhere near the first choice for the role of Han Solo. Kurt Russell's name is often mentioned to have been linked with it, but he was never actually offered the part. However the role of 'Han' was offered to, and turned down by, James Caan, Al Pacino, Jack Nicholson, Robert De Niro, Burt Reynolds and Jeff Goldblum - "Don't uh, get cocky kid"
5. Sticking with Han, he was originally supposed to be a green-skinned alien with gills. Lucas changed him to a human character so there would be more of a relationship between Han, Luke and Leia. This change caused the creation of Chewbacca.
6. The word 'Wookiee' comes from one of Lucas' earlier movies, THX 1138. During one scene a voice is heard on a police radio saying "I ran over a Wookiee back there on the expressway". This was an ad-libbed line by voice over artist Terry McGovern.
7. Greedo was both male and female! The alien wasn't a hermaphrodite, but was portrayed by two different actors during filming. In the scenes shot in the UK, Greedo is played by Paul Blake, and in the US scenes, Greedo is played by actress Maria de Aragon.
8. Amongst the actresses in contention for the role of Princess Leia included 15 year old Jodie Foster
9. The sound of the Tie Fighters engines was created by overlaying the noise of an Elephant trumpeting on top of the sound of a car driving on wet pavement.
10. Nowadays many movies bypass opening credits and get straight to the action, however in 1977 the Director's Guild insisted that all films begin this way. Rather than complying George Lucas paid a fine and subsequently resigned from the association. It wasn't long after the success of Star Wars that the rules were changed.
