While directing in theater that the actors will - I don't know if it's competitiveness or what it is, but they love to make each other laugh. They love to impress each other in rehearsal. They'll try something for a reaction. But in film, you're very often not all together in the room at the same time. You're shooting one day, somebody else is shooting the next. It's a totally different dynamic.
