If you're a fan of the novel that Brad Pitt's zombie vehicle is based on, the author has some bad news for you.

During a recent interview at Mansfield University, World War Z author Max Brooks was asked about his novel's adaptation to the big screen, and he said he expects the film will have the same title "and that's it." But Brooks doesn't sound too angry about all the changes the screenwriters may have heaped on his baby. As the son of legendary writer/director/comedian Mel Brooks and Oscar-winning actress Anne Bancroft, he knows how Hollywood works.

"I knew they were going to rewrite it," Brooks said. "I grew up in Hollywood. I knew it was going to go through a million changes."

We haven't seen World War Z yet, so we can't say for sure just how many changes will be made to Brooks' novel. We do know that the film has undergone rather extensive rewrites and reshoots on its way to a release next month, which could have brought it closer to or further away from the source material. As far as we know, Brooks has only seen trailers for the flick, but he noted he was invited to read the script after shooting began, and said no.

"I said: Why would I read this? This is not the movie you're going to make," Brooks said. "You're going to do rewrites and reshoots. That's what happens when you make a giant movie. "My attitude is if you haven't invited me in to contribute, then fine. Go make the movie you want to make and I'll see it when it comes out."

Brooks said his main concern as the release of the movie looms isn't how he'll feel about it, but how the book's fans will react when they find that some of their favorite moments have been drastically altered or simply removed. His advice: treat the book and the movie as two different things.

"I cannot guarantee that the movie will be the book that they love," Brooks said. "And I'm in no position to tell people to see this movie or not see it. If I'm asked I say: See the movie as a movie and judge it as a movie."

World War Z hits theaters June 21, so we'll all judge for ourselves then. What do you think? How different will the film wind up being?
