When I'm promoting a film, I'm not going to get caught up in anything else, and that includes all my personal things.

Yes, of course. Are you really so arrogant as to believe we are alone in this universe? Millions of stars, and we're supposed to be the only living creatures? No, there are many things out there, we just don't know.

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].

As a young actor, people were trying to define who I was before I really knew that for myself. But I still remember thinking, "This is what I love doing, and I hope I'm going to be able to do it forever."

I just want to help people. I'm a helper. For instance, I myself have helped hundreds of people get off drugs. In Scientology, we have the only successful drug rehabilitation program in the world. It's called Narconon.

I remember looking at my dad and wanting to understand him. I didn't want to just write the guy off. He was lost. I can't speak specifically in terms of why and how he got to where he was - that was his journey. All I can tell you is, he was overwhelmed by life... My mother basically did all the work, and then they got separated and I didn't see him for a long time. He didn't try to help the family financially or spiritually, and I lived with the effects of the chaos.

I don't pretend to be the character. I am the character.
