Well, for me, it's the relationship between comedy and life - that's the edge I live on, and maybe it's my protection against looking at the tragedy of it all. It's seeing life in balance. Comedy and tragedy co-exist. You can't have one without the other. I'm of the school that anything can be funny, if seen from a comedic point of view.

The cutting room is where you discover the optimal length of the movie.

Films are big hits when they touch a lot of people. Things are not funny in a vacuum, they're funny because we respond to some personal dislocation, some embarrassment, some humiliation, some pain we've suffered, or some desire we have.

You can't love somebody into a state of mental health. A lot of people get into serious relationships thinking they're going to heal someone with their love and attention, but it doesn't usually work out that way.

If people work together, if they can keep a cooperative spirit and use their ingenuity and balance it all with good humor and good will, then there's nothing to be afraid of. That's the sappy part of it, ... On the other hand, every Halloween for many years when my kids were trick-or-treating I would put on my 'Ghostbusters' jumpsuit with a police flashlight to protect all the kids from ghosts.

We are all several different people. There are different aspects of our nature that are competing.

For me, most comedy scripts fail in the mechanical playing-out of the setup. They'll pay lip service to a moral lesson or a psychological progression.
