"A scary movie puts a lot of people, a mob, in one place. There are advantages to that because the panic runs through the audience. If it's a good movie, the fear jumps from one person to the next. You can find yourself screaming just because everybody around you is screaming. There's a real atmosphere of terror. It's also visual, which means that you can't look away from this thing - it's happening. You're in the dark. It's like a nightmare. It's like a dream. It's very, very visual. It works on all those levels."
