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.

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.

I think Junior is certainly a science fiction premise as is Twins, as is Dave, beyond Ghostbusters.

I don't think my sense of humor has changed at all; I was born with this, for better or for worse.

I'd love to do a musical actually. My background is in music. I have a bachelors in music. I thought that I was going to be a composer, long ago when I first started. So it was amazingly fun to do those two routines in the film.

Well, actually, I did start out in comedies. Very, very early.

It's not that they all get along, or that there aren't bad people or people we make fun of. But at the core, there's a kind of sweetness.
