When you're doing a comedy and you want to somehow satirise people who are taking themselves seriously, I think the most serious genre is the thing you're going to get the most out of. If you're trying to satirise a comedy, it's hard to do that - it doesn't really work as well. But I love the war movie genre and I'm a fan of all those movies that are part of what this movie is.

I don't know what that weid fantasy is that makes people go, "Oh, you must have had a great childhood."

First of all, the first cut of the movie was like three and a half hours and I walked away going, 'Wow, I know there's like twenty minutes that I can cut - ' when I first saw it 'But I don't know after that.' The first time I put up then in front of people I was like, 'Oh, my God, I can take that out and that out and that out.'

My own parents were touchy-feely.

When I was growing up, This is Spinal Tap [1984] was the ultimate comedy, and it was the kind of thing I wanted to do. But you get to a point with parody where you can't go much further because ultimately it's feeding off of somebody else's creativity.

I recently watched that Lucie Arnaz-produced documentary [Lucy and Desi: A Home Movie, 1992] about her parents [Lucille Ball and Desi Arnaz], and I saw so much of my own childhood there.
