The most realistic blood I've seen is when Marlon Brando gets beat up in On The Waterfront.

Zombies are the blue-collar monsters

For a Catholic kid in parochial school, the only way to survive the beatings - by classmates, not the nuns - was to be the funny guy.

I keep a little notebook of things that I can do to the zombies that might be silly and fun.

A zombie film is not fun without a bunch of stupid people running around and observing how they fail to handle the situation.

I don't think you need to spend $40 million to be creepy. The best horror films are the ones that are much less endowed.

Collaborate, don't dictate. Every department head has something to offer. Listen and gratefully accept their offerings. They're moviemakers, too.
