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.
Jeff BridgesWe would do improvisation together. And that in a way, had almost a "student-film side" where we'd be sitting there with Robert Downey and Jon Favreau and we're playing around, we're jamming around and we read those pages and in next couple of days that's what we do, so it was a good experience. Kind of frightening at first because you didn't quite know how it was going to work out, but they had some very talented people there so it worked out well.
