There are dozens and dozens of improv classes across the nation, but it really cannot be taught.

Leadership cannot really be taught. It can only be learned.

I get asked, 'Who would you really like to work with?' I'm already working with them. Smart, talented, funny people, good musicians, an extended family, good friends.

To me, what I realized when we were doing 'Spinal Tap' - and the four of us wrote that - is, really, the core of that is the relationship with the two guys who grew up together and that strain when the girlfriend comes in. If that wasn't there, it's a very different movie. Then it's just bumbling guys stumbling along.

'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.

It's still important to be across the asset classes. A bit of everything goes a long way.
