Some quotes from the Twilight movie were added to the IMDb site:
Might have some Spoilers.QUOTESThese ones are from the Trailer, which can be seen here:James: Oh, still stubborn, aren't we? Is that what makes you so special to Edward?
Isabella Swan: How old are you?
Edward Cullen: Seventeen.
Isabella Swan: How long have you been seventeen?
Edward Cullen: ...awhile.
Isabella Swan: I'm not scared of you.
Edward Cullen: You really shouldn't have said that.
Emmett Cullen: This is *wrong*, Edward! She's not one of us!
These ones are from the movie provided by IMDb:Jessica Stanley: Bella! Guess who just asked me to prom. I totally thought Mike was gonna ask you, actually. Um, it's not gonna be weird though, right?
Isabella Swan: No, no. Zero weirdness. You guys are great together.
Jessica Stanley: I know, right?
James: You're alone...because you're faster than the others. But not stronger...I'm strong enough to kill you.
James: Beautiful. Very visually dynamic. I chose my sight well.
Isabella Swan: Are you going to tell me how you stopped the van?
Edward Cullen: Yeah. Umm I had an adrenaline rush. Its pretty common. You can google it.
I love that last one ^^

Totally imagine Robert saying that.
Here's some Trivia from the IMDb website as well:
Might be some Spoilers.-
Kristen Stewart has naturally green eyes. She wears brown contacts for filming because Bella is supposed to have brown eyes.
-
Kellan Lutz intended on keeping his natural curly hair for the role of Emmett Cullen. However, his previous role in _"Generation Kill" (2008) (mini)_ required a buzz cut and his hair didn't grow fast enough for the filming of Twilight.
-
Henry Cavill was Stephenie Meyer's first choice to play Edward, but by the time the film came to be, he was 25 years old, and no longer looked the part of a 17-year old. He was then offered the part of Carlisle Cullen but turned it down due to his commitment with 'The Tudors'
- For the role of Edward Cullen,
Robert Pattinson flew from England to director Catherine Hardwicke's house to audition. There, he and Kristen Stewart, who was already cast as Bella Swan, rehearsed the "Love Scene"/"Meadow Scene" on Hardwicke's own bed.
- All of the actors playing the Cullens wear topaz-colored contacts.
I'll post some pictures of the actors playing who soon. Not that anyone will care

But I'm gonna do it!
