Back then, you seemed like a crazy person when you were trying to push the boundaries of network TV. People looked at you, and they were offended by the fact that you didn't follow the generic rules of what was expected on network TV.

The only thing I knew in the world as a little kid was comedy. And no other kids in my school cared about it at all. There was no one to talk about it with. You know, we're in a geek culture now where comedy is so giant. I'm one of the people that, you know, works on Funny or Die. And there is just a giant culture of comedy nerds. But back then, I was alone, and I had a little confidence about it because I felt like, this is my thing, this is the only thing that only I know about.

I loved working in stand-up, and I always dreamed that I could make a movie about it. I didn't know if I would have the courage to, because if you make a bad movie about stand-up, then comedians will mock you for the rest of your life. They're still mad about movies made 25 years ago. But it was always a dream of mine, and I was glad I finally came up with an idea that allowed me to explore it in such a way that it's not all about stand-up, but stand-up creates a great backdrop for another type of story.

All my cuts are always about three hours, at the start, mainly because any scene in the movie that's 90 seconds, I probably shot a five-minute version of. If you just extrapolate that through the whole movie, I have a very long version of every scene, usually because, if there's one funny joke, I'll shoot five because I don't know if the one I like is going to work. I'll get back-ups because my biggest fear is to be in previews, testing the movie, and a joke doesn't work, but I have no way to fix it because I have no other line.

I thought the idea Jim [Carrey] had, which was to do a comedic version of movies like The Hand That Rocks The Cradle and Unlawful Entry, was really funny. The movie was a little lighter when we first came on, a little more like What About Bob? or something.

At network television you could make a show like Freaks and Geeks, and even though 7 million people watch is every week, you were considered a terrible failure, and they got rid of you and staff. Now ... It's like a world where the replacements are the biggest fans in the world. It's, the Elvis Costellos of television are the winners. Creativity is king and it's very very exciting.

You can do weird things on TV - there are happy stories, sad stories, dark stories. But with a movie, it always has to end satisfying. Unless you're the Coen brothers, and it ends with somebody getting shot in the head.
