I'm the biggest proponent of test screenings now. There's two ways to face test screenings. For dramas, I don't know if I would rely on them as much, although I still think you need them, because you're making a movie for an audience at the end of the day. But with comedy... You could go through a script or anything I ever worked on, where you go, "This is hilarious," and you put it in front of people and you get nothing. And then the other side of it, is something you're like, "I think this is really stupid," and it gets a giant laugh.

One of the biggest things you have is your reputation and your reputation with knowing what's good and what's not good.

I just love Kate. [Bieber], to me, is one of the funniest impressions because it's so all encompassing. It's like a total body and soul impression. But that's Kate. Every character she does is that way.

Many Republicans have always reminded me of professional WWF wrestlers. They come into the ring all pumped up and acting like they're invincible and that they're going to destroy their opponent. Then they get hit once and fall down and roll around in agony and suddenly seem immobilized by pain, calling for the ref to intervene.

What you want is the thing that critics love and audiences love, but that's the hardest thing to do.

What I don't like is when I see stuff that I know has had a lot of improv done or is playing around where there's no purpose to the scene other than to just be funny. What you don't want is funny scene, funny scene, funny scene, and now here's the epiphany scene and then the movie's over.

I've made a career making stuff that nobody sees, so anything that I can do to help make something that people are going to enjoy and want to see over and over again, then I'm there.
