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.

As an actor, you're completely at the mercy of other people. You basically go begging for the opportunity to work. As a writer, at least nobody can tell me what to do. I can write what I want. I might not sell it, but at least I'm in control.

You don't have to know much, just a little bit more than everybody else.

The comic edge of Ghostbusters will always be the same. It's still treating the supernatural with a totally mundane sensibility. In the world of ghostbusting, there are certain givens. You're always going to have some new invented technology, some pseudo-science that sounds right because we drop enough familiar terms from physics and engineering, and pseudo-methodology, something that people will think they may have read something about before.

When you're young and you first see the extent and depth of the world's hypocrisy, it's fun to go after it. But by the time you're sixty, it's so commonplace. What's the point in ridiculing people anymore? Their existence itself is a sort of sick joke.

As much as I liked acting for its playfulness and the reward of hearing big laughs wash over you on a stage, I always felt I should do something that I could control.

If people offer me decent roles in good films, of course I'll take it. But I just didn't like the actor lifestyle. You end up focusing all your energy on trying to get parts you don't even want.
