My true role is to get actors to understand what the camera is doing and what my intent is so they don't waste their good stuff on over-the-shoulder shots and wide shots. They need to know when we're going in to get something important, so they know to really go for it. No human being can give you 1,000 percent on every single take or shot, so you need to let them know what you're heading for. It's important that the actors know they're being looked after and being recorded in a way so they can do their best.
