So if you want to have a great video game-based movie you have to keep the mood of the game, use the normal character setup - but you have to flesh out the story and provide more background for the characters.

A lot of the main audience thinks video game-based movies are always horror movies but it's totally not true. In video games you have adventure, sci-fi, horror, action and even comedy. I think that people should accept more that video games are kind of like the best-selling books of the new generation.

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.

I want to be like, "Look at Postal like Quentin Tarantino did it. Brainwash yourself and convince yourself that Tarantino did it. Forget my name and enjoy the 100 minutes and then write your review."

In Germany, people are saying, "George W. Bush is an asshole. Osama Bin Laden is an asshole." But then I make jokes about Auschwitz, and how the Germans are lederhosen-wearing sausage freaks - and they hate me for this! And I'm like, "You all are sitting there because you want to relax and have a nice evening, and now you're pissed because I put also a mirror in front of you."

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.

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.
