When I did Casual, I just let myself put on weight because he's a schoolteacher. He's not meant to be muscle-y.

I had done a little bit one other time. This character [in Jack Reacher] is a psychopath, but I had been hired by Carlton Cuse and Randall Wallace.

It's pretty tough on your loved ones to try to get back into a rhythm, especially when all you want to do is do nothing.

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 read as many books about the psychology of a psychopath as I could and I researched what exactly happens to soldiers.

I only had a three-week break from the beginning of Bent, so I went from one thing to the next. I got back [from shooting Jack Reacher] and there was a sense of, "Oh my God, what do I do now?" I don't have personal trainers around me all the time, I'm not on a meal plan, which I had been on for almost a year straight. There was a lot of sleeping.

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.
