Making a film is so hard that if you don't have your main actors going along with the ride with the rest of the crew it can make your life very difficult.
People want to see realism in action now. People want the actors to perform than the computers performing. Though I have done both, I enjoy the realism of action more.
Everyone is sort of in their own little area counting lines and no one talks when film's not rolling. There's constantly actors coming to me back behind the monitor screaming at me, "Why did my line count drop?" It's a nasty tense environment.
When I was a younger actor, I would try to keep it serious all day. But I have found, later on, that the lighter I am about things when I'm going to do a big scene that's dramatic and takes a lot out of you, the better off I am when I come to it.
the audience is the controlling factor in the actor's life. It is practically infallible, since there is no appeal from its verdict. It is a little like a supreme court composed of irresponsible minors.
