I always look for a challenge and something that's different.

I'm usually nervous to meet people that I admire because what if they're not cool or something?

I've had a very interesting life. There are ways of handling the complexities. I'm willing to take on the responsibilities as a father, as a producer, as an actor; and I enjoy that. I've always been changing and evolving and growing. There's no pinnacle of power where you can sit back and relax.

When I work, I'm the actor. I'm going to do my job. I'm not going to direct the movie. If I wanted to direct it, I would direct it. I wanted J.J. Abrams to direct Mission: Impossible. I work with people that I respect. I expect them to do their jobs, and I will do mine. And I am there as a producer to help in any way, but no one makes a movie by themselves. It's a collaboration.

For me, to take a movie and travel the world and go and work with these cultures and an international cast and have this spy thriller that's not just about character but also action and suspense, they're very challenging films as a producer to make, creating stories, creating set pieces that serve this character [Ethan Hunt].

Psychiatry is a pseudoscience.... You don't know the history of psychiatry. I do...Matt, Matt, Matt, Matt, Matt, Matt, you don't even -you're glib. You don't even know what Ritalin is.

I've never done work for money, ever. If your choices are based on grosses and the film doesn't do well, what does that mean? It leaves you with nothing.
