Much of my youth was spent in the parking lot or inside a Dunkin' Donuts.
Horror is like comedy. Woody Allen's comedy is going to be very different from Ben Stiller's comedy which is going to be different from Adam Sandler's comedy which is going to be different from Judd Apatow's comedy. They're all comedy, but they're all very different types and you can enjoy all of them. Horror is the same way.
As a director, you have to know what actors are doing. You're the one telling them what to do. The actors' job is to come prepared to the set, but sometimes, if they're beginning actors or people who are non-actors, you have to teach them how to act.
The one negative to horror is that it's always law of diminishing returns. When you go in the funhouse, the ride is never scary the second time. You will never have that pure experience as when you first watch it.
