Essentially, I'm untrained, so I just go with my imagination and try to put myself as solidly as I can into the shoes of whatever person I'm going to be playing.

I tend to stay in character between scenes... to be rather serious on set, but here's why, and I think people will find it surprising. I'm one of the worst 'corpses' on a movie set, which means you can't keep a straight face. You start to get the giggles and you can't stop.

'Batman' took 10 months to film, and by the time I stopped working on it, it took a long time before my English accent came out again. I was actually having to try for it.

In honesty, there are probably a lot of stories that can be told with Batman. I like the idea of him growing older and he can't quite do it as much anymore.

I know a lot of other actors that don't like to look at other references to their characters and things. But I like it. I always look at everything, I read all the books. I read Dieter's "Escape from Laos." I watched the documentary again and again and again. I recorded it just to listen to him a lot. I just don't suffer from feeling like I'm getting caught into an imitation. I just feel like I want to steal some good stuff if it's in there.

But I enjoyed getting sick, I didn't mind it at all. So in that short amount of time, I did actually go from 121 right back up to 180, which is way too fast obviously. And that resulted in some doctors visits to get things sorted out.

I find something fascinating about the quiet man in the background who has no desire to be the center of attention.
