MARTIN: What does it mean to turn into a werewolf?Read the rest here.
LAUTNER: I think the most important thing with Jacob is that pre-transformation, he’s clumsy. He trips over his own feet. As soon as he transforms, he’s very agile. At one point, he flings himself through Bella’s window and lands at her feet, and that’s the first time Bella realizes this is a new Jacob: He never used to be this agile. I loved bringing out that side of him. The bummer is, when he becomes a wolf, that’s not actually me. When he does the cool fight scenes, he’s transformed into CGI.
