In theater, there's a lot of discipline involved in doing eight shows a week for a year and a half. It's nice to be able to bring some of that bag of tools with you over to the film world, where you don't have the rehearsal, you don't have an audience. You don't have a month of rehearsal to examine these words, and you meet the guy who's going to play your brother the morning that you shoot the scene. So you need a bag of tools.
