I ask my assistants if they're retarded all the time. When the camera is on you, of course, actors have the ability to make it real. For me, if I'm not talking, it is a problem. I have so much more respect for actors after being in front of the camera, and I realize that the hardest part is when you're not talking. Listening is harder than just acting. Listening is the hardest part.
