"I'm a comic book nerd at heart, so I'd like to see the relationship between Thor and Sif progress," she said when asked where she would like to see the character go. "Whether or not they do that, we're not sure yet. We'll see. I think that element will be in there, but I don’t know how much."
She was also asked whether we might see Sif in Marvel's The Avengers. "Sometimes you never know. It'll be funny - they'll call you and they'll do a post-credits scene and you go, 'Oh, so everything I said in interviews is completely wrong.' So you never know!"
