One interesting thing about jazz, or art in general, but jazz especially is such an individual art form in the sense that improvisation is such a big part of it, so it feels like it should be less soldiers in an army and more like free spirits melding. And yet, big band jazz has a real military side to it.
I wanted to look at the mentality that can breed that sort of intensity, that kind of cutthroat, pressure-cooker feeling, especially a form of music like jazz, that should be - or you'd think should be - all about liberation and improvisation and everything.
I didn't have traditional stage fright. If there was 500 people in the audience or three people in the audience, it didn't really make a difference. What made a difference was the conductor. Everything that I was scared about as a drummer was him. It was his face. It was whether or not he'd approve of my playing.
The go-to reflex all over Hollywood is still likeability. I've always had a problem with it because I think I have a weird barometer in the sense that some of the characters I've cared about the most in movies are characters that are often thought of as despicable.
When you're trying to paint a portrait of a very specific world, you're trying to show what makes the world different. So, sometimes it means exaggerating certain kind of aspects, but I don't think it's that important or it's that much of an issue as long as you get an emotional truth across.
