I was in good shape from Divergent. Damien Chazelle, the director of Whiplash told me, 'Stop Working Out! Don't go outside!' He wanted me pale and doughy. This is the first movie where I shut myself off from the world. It was, by far, the hardest thing I've ever done.

Acting is such a high art, and coming from theater, I know how hard it is and respect the craft. I want to look back when it ends, and say I challenged myself. I wanted to be an actor you always remember, and those who are the great ones. That's just a personal journey. If you're too comfortable you're taking it too easy. The director can direct you for two months but before that it's just you and your internal drive. I want people to go to my movies and know it'll be good, and with great actors. You never know what you'll learn from just staying in the same space with them.

My mom is very proud of introducing music to all her kids. But I played in some bad rock bands my junior and senior years of high school.

I've always felt like I can dance.

Naked acrobatics are on my resume.

Living in somebody else's pain for an actor man, it's actually nice when you get to feel that kind of emotion. That's what I like.

When I first started getting into acting, I was doing improv in acting class, and I had done a serious monologue and everyone was cracking up laughing and I went to the drama teacher and said I don't want to be the class clown anymore, I want to do serious work, too, and they loved that, and so I started mixing in drama.
