I like when things are hard; I'm very competitive. If something seems difficult or impossible, it interests me.

Acting, films, scripts, is literally the only thing I’m 100 percent confident in. I know what I’m doing. I just understand it, and I love it. When I’m on set, that’s when I feel the most at home and in control.

I just don't like that you can either be ugly and smart or pretty and dumb, or ugly and nice or pretty and mean.

I am ashamed to say I auditioned three times before I even watched any of the [X-Men] movies. And then after I watched the movies, I was like, "Oh my God, I've been doing it all wrong, why are they calling me back?

I wasn't pretty enough to play the popular girl, I wasn't mousy enough to be the mousy girl, so I never fit in. And so I'd get close, but I never got anywhere, and it was really painful.

For 'X-Men' I was lifting a lot of weights. I actually lost a lot of mass when I quit 'X-Men' because I was working out so much and very muscular and strong.

Once I'm obsessed with somebody, I'm terrified of them instantly. I'm not scared of them - I'm scared of me and how I will react. Like, for instance, one time someone was introducing me to Bill Maher, and I saw Meryl Streep walk into the room, and I literally put my hand right in Bill Maher's face and said, "Not now, Bill!", and I just stared at Meryl Streep... I just creepily stared at her.
