Scripts are a house of cards and you can't just reach in the middle and pull out the middle card because the house of cards will fall down. But at a certain point you almost have to allow that house of cards to get knocked down a few times because you need to make it sturdier. How many times do you hear, "No, that doesn't make sense," or "Why would this happen?" That was a mistake. You shouldn't have those moments, because the moment you're knocked out of the story, then you're dead. And all you can go is moment to moment,or joke to joke. And that's gonna wear people out.

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.

Handheld camera is approximating what we're seeing when we're looking at each other, and kind of looking around, and your eyes whipping around. It adds an immediacy, where you feel like you are watching something through your own eyes, standing there with them. And that just allows you to take more liberties and have more fun with people's behavior.

What you never want to do is have a story that doesn't track emotionally, because then you're going joke to joke and you're going to fatigue the audience. The only thing that's going to string them to the next joke is how successful the previous joke is.

Film, television, and working with a camera is such an intimate art form that if a camera is right on you, and I've got your face filling the screen, you have to be real. If you do anything that is fake, you're not going to get away with it, because the camera is right there, and the story is being told in a very real way.

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

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