The one benefit of having done all kinds of movies as an actor is, you learn the pros and cons of being tempted to do a really big movie because it costs a lot of money.
You can say what you want about me. You can yell at me with a video camera and be TMZ. You can follow me around and take pictures all you want. I don't care.
I like roundtables because you can talk more directly to people. And you also can get kind of a vibe on what a journalist's take is on something, and have a conversation with them more.
When I look up at the screen and see myself I always have to laugh. Not because I think I'm doing a horrible job, quite the contrary, I just feel it's so surreal to feel like one person can entertain so many at one time.
To answer the question, though: I didn't always want to direct. I just liked the idea of it. If a friend was making a short and needed someone who knew screen direction, I would jump in. It would be horrible, but it led to a short, then another, and another. It was like student films.
As an actor, you can steer a scene in another direction by playing it a little differently. And honestly? I like being an actor, and I want to keep having a career.
