Psychopaths don't have that charming skill set. They definitely manipulate, but they do it through focused, unskilled means. They're more obsessive.

I change myself a lot. Some roles you don't want to be big, bulky, muscle-y guy and some roles you want to be a lean, marathon-runner physical type. And some roles you just don't want to be in shape.

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.

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

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".

The director, Moisés Kaufman, just received the national medal of the arts from President [Barack] Obama . He wrote and directed The Laramie Project and he has directed several Pulitzer prize-winning plays. He's a pretty profound director in the theater.
