The greatest way for people to experience a comedy is to go in not knowing anything about it. But because of marketing, it's impossible. Marketing meaning that in order to get people to come you can't just go, 'Hey, there's a great movie - we're not going to show you anything from it but trust us!

Katie Dippold, who I wrote the script with, she's very into ghosts and all that. So I go, "Hey, why don't you talk to Katie?"

So many stars who have shows are intimidated by having people around them be funnier than them. It's always the unsuccessful ones. Look at Seinfeld - he's great because he let everyone be hilarious.

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.

I always hated high-school shows and high-school movies, because they were always about the cool kids. It was always about dating and sex, and all the popular kids, and the good-looking kids. And the nerds were super-nerdy cartoons, with tape on their glasses. I never saw 'my people' portrayed accurately.

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

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.
