You realize as a director that when you are cutting a film, you want to have alternatives. You need color and choices. You don't want four takes that are identical.
I like the old school heavy metal bands like AC/DC and Aeromith. I like that type of music. As the director, I tried to influence the type of music the bands in the movie would play.
I discovered martial arts, first judo and then karate, and I became quite good at it, because I had something to prove. And more than anything, I needed to feel safe.
My sensei was a British karate champion named Brian Fitkin. He was my mentor and because I had a hard relationship with my dad, he became a father figure to me.
There are a lot of great athletes who stop working out, and they get out of shape like everybody else in their 30s and 40s.
