I wouldn't say I'm a connoisseur of film. I like certain films, but I don't pretend to be a connoisseur of films, no.

We populate the stories with people who share certain traits. Invariably, someone will say, "I know that guy." Every world has odd people.

People want me to be funny all the time. They think I'm being funny no matter what I say or do and that's not the case.

'This is Spinal Tap' was a film we felt really had to be done like that. It wouldn't have worked any other way. And it turned out to be the first time a fiction film had really been made in a documentary format. I continued to do that, obviously, because it's a fun way to work.

I like to play music, and I like to be funny, so I just do both at the same time.

Comedy is like music. You have to know the key and you have to find players with good chops.
