I remember in one of my early films I had a drunk scene. It was Kiss Me Goodbye, with Sally Field, and I was playing this kind of nerdy guy who gets drunk and dances. And so I thought, "Oh well, I'll just get drunk and do the dance." And it was wonderful, but then I had the rest of the day, and the next day. So I learned that you don't really have to do the things that your character is doing. But us actors, we use something called sense memory. I've certainly been drunk before, and part of my job is to recall that without getting drunk.
