The real trick for me as a director is to make sure that people don't start pushing because the harder you push as a perform the less funny it becomes.

Then my first film was something called Cannibal Girls, which sounds like a horror movie but was actually kind of a goofy comedy with horror elements. Like a horror spoof.

The home viewing experience is slightly different and there's room for these kinds of extra excursions.

I've always believed in populating my films with characters who we like, who we have some warmth for, who have warmth for each other, who we would like to hang out with, who we emulate in one way or another.

When you're working with movie stars, part of the deal is that, if they have something to say, you'd better listen. You don't have to absolutely listen and not talk, but there is another creative force at work, and to be successful working with movie stars, you have to bring that force to work for you. You have to find something that's comfortable for them, and at the same time, that's in the parameters of what you're trying to do yourself.

It's been about 15 years, and I've never really worked seriously in CGI and I thought that here was an opportunity to do the kinds of things that I was not able to do on Ghostbusters.

It's sort of the most important thing for acting, is to listen to the person you're dealing with.
