Robert De Niro
Actor
I always go back to how people behave. If you watch how people actually behave in a situation, it's very simple and honest and contained. You don't need to use as much expression, as much feeling. Some characters will boil over, and that's another thing, but a lot of times I think you can just do very, very little.
