The last time I did a movie that needed a horse, I said: 'If it moves, I'm out of here.' The worst thing is, they know when you're afraid and act up accordingly. I've had them run off on me. Horses I do not like.
I like to be cast well and then I like to be left alone. And good directors, that's generally what they do when they hire you because you have something that's useful to the part, and then they leave you alone. The times that I've run into trouble is when, very rare actually, but you get hired and then there's some sort of makeover involved.
Acting is a bit like being an athlete. You spend all your time getting ready to do something for two minutes. All the things that made my career in the movies happen took two or three minutes, which is the time that it takes for a 'take'. In that time, something happens. That's what people know you for, just like someone running the hundred metres.
In rehearsal you have a good accident that you can repeat.In the movies if you have a good accident you hope the camera's running.
