When you do one movie at a time, if one goes crazy and becomes successful, your life changes. But you can step back and catch your breath.

I decided to make 'Captain America' because I realized I wasn't doing the film because it terrified me. You can't make decisions based on fear.

I didn't realize - you think you are doing a movie but then you realize it's a Columbia Pictures movie so it's probably going to have some publicity. Then you see a billboard and it's like, 'God! I'm on a billboard!' It doesn't hit all at once, it kind of unravels itself and it's still unraveling.

He doesn't have demons. He's not Batman, he doesn't struggle with inner turmoil. The nature of this character is that he puts himself last and helps the common good. So he could easily slip into a world of boredom, The blessing and curse of Captain America is that he doesn't have that fancy an ability. He doesn't live in another world, or turn green. He doesn't have bells and whistles, he doesn't shoot missiles. He punches and kicks.

I'm not that great with press sometimes.

If I do cardio I'll disappear.

I'm a big fan of working out on my own. I put my headphones on and I'm pretty good at self-motivating. At the end of the day, I enjoy it. Once I'm there and once I get going, I tend to love it, and I feel good.
