We did casting in L.A. and a lot of people came against the advice of their agents. The agents said, "You shouldn't be in Postal, it will damage your career." So Zack Ward came to casting and played one of the cop parts, and then later I looked at the DVDs again and said, "This guy is Postal Dude." He's like white trailer trash. He's had a long time in the film industry, but no real success. He needs money; he's two-times divorced in real life. He said he works only to pay off his Philippine ex-wife.

I think it's better to be too early and disturb a few people - but have other people say it was necessary - than to do it way after the fact. We shouldn't forget that Charlie Chaplin did a movie about Hitler while Hitler was alive, and Peter Sellers in Stanley Kubrick's masterpiece Dr. Strangelove was during the McCarthy time, where everybody was a communist and McCarthy was flipping completely out. I think it's important to have a movie like Postal now, where we are on the peak of the Iraq War, on the peak of terrorist attacks, where everything is actually happening.

Of course there are a lot of books that are interesting to make movies out of, but on the other hand, I think video games are also kind of like bestselling books for the younger generation, and the younger generation is the one going to the theaters.

I think video games are a great kind of entertainment. They have replaced a lot of games people normally play with their friends and neighbours, like Monopoly.

Interview with a Vampire was lots of sex, so I'm not sure.

The Postal is a ruthless, Mad TV-type thing. We sent out a DVD to the South Park producers, and they liked the movie so much that we can say now, "It's like South Park with real actors" on the trailers and posters.

Slater's a big star and he's been in the business a long time. He's always in a good mood and easygoing but he takes his character very seriously.
