Sometimes people don't rehearse at all, but you might have had a chance to rehearse for a few days, or even more than that. Then in the moment when the camera's running is the only time it matters. So whatever you've discussed or thought about or discussed with the director, the other actors, hopefully there's a part of the experience that you've left open so that only in that moment the camera catches it. That's of course the hardest thing to do because everything is planned and you have thought about it in advance.

It's always tricky to watch yourself, always. When I first had to watch myself, it was really hard because I'd done quite a few plays and I've never seen myself. So I was professional but I'd never watched myself. So I was like hearing you know... I'm sure you guys are all much more familiar with that because everybody has a phone, and everyone's taking pictures of themselves and making movies of themselves. And so people are more accustomed to it now. So I had to get used to it because there's a lot to be learned, of course, as an actor. When you watch yourself, you learn a lot.

Once I get on something, once I have something that I'm working on, then I become very obsessive. In a good way. I mean,... is there a positive way to say obsessive? It's a good thing and if you're out there and you're working on something right now and you're crazed and you're up in the middle of the night, or you can't stop thinking about it, or you have to keep reading other things about the subject that you're working on or whatever. That's good and I think that's necessary creatively.

Movies are details. Movies are billions of details that come into a certain moment. So with all the years and months and weeks and days and minutes of preparation, then finally you're shooting and it all comes down to these moments when you're shooting, which is sort of insane when you think about it. The details make a difference.

There's a lot of different ways of going about teaching acting and ultimately you have to just kind of create your own. You have to be the author of your own acting school in a way. I mean you can take from this and this and you can watch people and you can watch performances on the stage. You can watch movies. But ultimately you have to figure it out for yourself.

I think where I've instinctively found myself is that I am somewhat guarded in my public life. Being interviewed or being photographed or just in public attention, I have a certain reserve. But when I'm working I feel like I'm very open. At least I like to believe that I feel like nothing is held back when I'm in front of a camera. That's my job.

Movie is a near art form. It's showbiz and people want to make money. And generally people are financing things because they think it will make money whether it's a cable news show, a cable show, or a feature film, or whatever it is. So that's the part of it that drives it, I think, is really the dollar.
