Rob and Kristen: What's My Motivation?

We know the plot and have seen the way the characters turned out on screen. Rob and Kristen explained to MyParkMag their theories behind properly portraying Edward and Bella:

Rob

"The way I wanted to play him was more of powerlessness, like he's a kind of helpless character. He was unconscious when he was made into a vampire. He didn't have a choice.

"He woke up three days later and he has to kill people and he doesn't know why. He finds out that he's never going to age and he's going to live forever, and he's like this Superman guy but he never asked for it.

"But before that night he was this normal seventeen year old and now he has to go off and kill a bunch of people and it's all his surrogate father figure's fault – he's like an eternal adolescent. He's very frustrated."

Kristen

"My favourite thing about Bella is that she is supposed to fill this role of the damsel in distress, but in an odd way she sort of holds the power in the relationship.

"She is very sure of herself and is not afraid of the situation which is so much bigger than her. Bella and Edward have like a funny dynamic.
"He's a vampire and he would suck the last bit of blood out of her, yet she's completely fascinated by him."
