The 18-year-old actress shared with the music-movie channel that she wouldn’t actually be diving off a cliff, but rather a CGI (computer generated) Bella Swan would.
Kristen shared, “I get to almost jump, and then no. I’m not going to do the cliff-diving, unfortunately. I went to do a head-scan the other day and it had to be my ‘determined’ look. They were like, ‘You’re just about to jump, so [pretend] like you’re about to scream or something.’ I was like, ‘No, no, no. She’s set [to do it]. Every face [had to] look exactly the same. So I was like, ‘I can’t move? But I have to make the [jumping off a cliff] expression? Bella is going to be jumping off the cliff going like [she's contemplating stuff].”
