When I came on to Jack Reacher, I had just taken my girlfriend on vacation and ate everything I could. I put on about 15 pounds, so when I met [the Jack Reacher team] I was clocking in at about 180. They looked at me and were like, "You're just gonna lose five pounds, we're gonna keep you skinny".

I'm obsessive about my job and I want it to be as great as it can possibly be, especially right now in these early parts of my career.

I'm a trained actor and I can always tone it down, I can always simplify the work I've done. But if I'm asked to bring the nuanced and complicated work, I'll have it in my pocket, and all that information helps.

[Jack Reacher] is the longest I'd ever shot anything - and let's be clear, this is my first studio feature film - so there was a huge learning curve.

When I look at myself in the mirror, I don't see the bad guy.

The guy [Tom Cruise] is a machine.

I was eating with the help of a nutritionist so I was definitely putting in the appropriate calories and vitamins and minerals into my body; however, it was still so little that if I had the tiniest piece of sugar, my brain would go crazy. If I had some alcohol during the run of that play, my brain would go crazy.
