"When you are on the set, you have different departments - you got camera, sound, props, hair, makeup, catering, executives. Imagine each one of those are spokes on the wagon wheel. All the spokes come into a hub: the hub is the director. The wood the spokes go into are distribution and promotion; the steel wheel around the hub is the film. None of these have anything in common with each other."

We did some camera tests blacking it out, we made a prosthetic with a gap in it, but that made me look like a donkey, so I vetoed that right away. And then I just finally called my dentist and said, 'You know, I've had this implant for 20 years. What's it involve in taking it out?' And he said, 'It's actually not that big a deal. We can do that.' So we took it out and I was toothless for three months, for the run of the movie [ The Hangover] .I take my job very seriously.
