I think you should do rehearsal and work at it, but when the camera rolls, you should be ready. Try to make it good the first time.
Oliver StoneI believe in intermissions. I lived through this experience with JFK and Nixon. JFK should have had an intermission. It should have come right after the Donald Sutherland scene, because then there's just too much information flooding in. You need a break. Same on Nixon. It was a long film, but I couldn't help it, with that kind of subject.
