EW has a review of Rob’s audio commentary on the Twilight DVD. Here is an example of some of the funnier moments, but you can always wait and watch the DVD if you don’t want to spoil it.

15:40 “That was really impressive…,” he says when Stewart’s Bella slips and falls on some ice. “What was impressive?” Stewart asks. “That falling over thing,” he says. You can hear her rolling her eyes. “That’s tough…. Do you just fall on your ass?” “Yeah, I just basically fell down.” (This was funny, because he was actually trying to be serious, I think. It won’t happen again.)

17:00 Pattinson insists we all have to see the audition tape he made of the scene where Edward returns from his hunting trip and finally speaks to Bella in biology. “It’s the funniest thing you’ve ever seen in your entire life.” He says he performed it with a guy, who did a woman’s voice. It’s all very earnest. “Dude, I’m glad you didn’t send that, right?” Hardwicke asks, sounding genuinely concerned that if he had, he wouldn’t have gotten the role. (That’s why he didn’t send it.)
