I've been encouraging documentary filmmakers to use more and more humor, and they're loath to do that because they think if it's a documentary it has to be deadly serious - it has to be like medicine that you're supposed to take. And I think it's what keeps the mass audience from going to documentaries.

If we made that list, we actually are in agreement on more things.

First of all, the American people are inundated with advertisement after advertisement of you buy, buy, buy. You've got to have the latest thing. The iPad 1 isn't any good anymore, you've got to have the iPad 2. The iPhone 4, now you've got to have iPhone 4S. Now you've got to have the 5b, now you've got to have the 6c.

For a documentary filmmaker, I do very well.
