Movies are this thing that came into my life, and it still feels pretend in some way. I kind of do this thing, and I never really accepted this idea that I'm a film actor. That's what I do. I feel like I'm a theater actor that started doing films. Most people have never seen me in a play. They're fun, though.

I was thinking maybe about being a lawyer. I realized I was interested in becoming a priest at one point. I was just interested in stuff where I could do something I really believed in. And then, I realized if I become an actor, I don't have to choose. I get to do everything. It's worked out so far. But what I really want to do is direct.

This is real human drama, we're not creating some amusement park ride for the summer. Even though the movie is really exciting to watch, it's got a real pathos behind it.

Whatever the reasons that I turn things down, I'm always happy when there's a good result, and I can enjoy it as a movie, you know? I don't feel like, 'Oh man, that was really good. I should have done it.' You have to make the decisions you have to make, whether it has to do with your family or repeating a character or whatever it is.

Hey, I'm just trying to become the Michael Caine/Gene Hackman of my generation.

Improvisation, the main thing is it teaches you to be in the moment and present in the moment and be reactive and proactive for what's going on. Someone gives you something - a lot of actors are a little shut off, so they're just doing, "This is my character, these are my lines, I'm going to just send it to you then you send whatever you're sending." Improvisation teaches you to really be listening.

When I first joined SAG, there was another John Reilly. My dad was John Reilly, too, but growing up I was John John. Nobody in life calls me John C. It's more like, "Hey you, Step Brother!"
