Robert Pattinson unknowingly contributed two songs to this film. Apparently, he didn't know that "a mysterious third party" had given the director a copy of music he had recorded years ago. She decided to use two of the songs, and he was surprised to hear them when viewing early film footage. The songs are: "Never Think" [playing during the restaurant scene] and "Let Me Sign" (plays during the scene where Edward has to drink Bella's blood to save her). Pattinson said he was overwhelmed by how well "Let Me Sign" fit into the film.
Stephenie Meyer wrote a parallel novel (unfinished) to 'Twilight' called 'Midnight Sun.' It tells the story of the first book from Edward's point of view. In it, he comments that the arrival of Bella to the school has all of the boys "acting like they're in first grade and she's the shiny new toy". This thought is spoken aloud by Jessica during Bella's first lunch in the cafeteria.
The original release date for Twilight was December 12, 2008. When the release date for 'Harry Potter and the Half-Blood Prince (2009)' was moved from November 21, 2008, to July 17, 2009, Twilight's release date was moved forward to November 21 in a attempt to fill the Harry Potter gap.

The Cullen family crest (seen worn by all the Cullens) is a lion with a hand over its head, and a downward pointing Chevron with 3 clovers.

Even though there is a song by Radiohead in the movie, it never made it to the official soundtrack album.
