I didn't really make up my mind to be an actor until I did 'The Hitcher' with Rutger Hauer. I was about 17 or 18 when I did that, by which point I'd probably done a dozen or more movies or TV things, but 'The Hitcher' was the experience that made me want to study and commit and learn how to do this for my life.
I feel like actors, having spent a lot of time on movie sets, tend to make decent directors, because they've been there, they know what they're doing, they've seen it done right, they've seen it done wrong, and they feel comfortable. There's not a lot of chin-scratching and wondering what your next move is.
To be a good director, you have to spend a lot of time on actual sets, but today, there's a lot of people who spend a lot of time in dark rooms writing a script, and they'll go in and tell the story to some suit at a studio who says, 'Okay, this is great, let's go.' But that doesn't necessarily mean you know what to do once you're on set.
