I went into very deep research as to what exactly that meant and how sociopaths function psychologically and within the world.

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.

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

You get a role like this in a big action movie [like Jack Reacher] and you can go one of two ways: you can paint in broad strokes, which happens a lot in action films, or you can get very detailed.

I want to make sure everything has my 100%.

Sociopaths are more complicated psychopaths; the difference between a sociopath and a psychopath is a sociopath is incredibly charming. There are a lot of sociopaths that are CEOs. They don't necessarily kill people but they're able to walk into a big social function and make everybody think they're the kindest, coolest, smartest, most interesting person in the room.

I had heard that Tom [Cruise] was the same way, that he is incredibly dedicated. I was very excited to meet him and I was, honest to God, weirdly surprised that the guy makes me look lazy. I think he does think I'm a hard worker, but he makes me look like I'm doing nothing. The guy is at the gym before anybody in the morning.
