I started doing community theater when I was seven and I think the intent was just expression. When you're a musician, you can make music in your room, and when you're a writer, you can write. Acting is one of the tricky art forms where you need a certain amount of permission to be able to do it. You can talk to yourself in the mirror, but it's different than actually acting or doing a scene. You need an audience and you need someone else to do it with.

Comedy is funny when it comes from truth, and that's always the rule of them. It's about how far you can push that boundary.

Regardless of what kind of film, the number one rule of comedy is to never take yourself too seriously and then the next rule is you can't have any self-consciousness, otherwise it kills the laugh, and that will never change.

As an actor, when you're doing comedies, you're around fantastic, funny people and you hopefully have a really good time doing it.

I think casting a show is an art form in and of itself. We're all so different - the cast is made up partly of real stand-ups, partly of actors, and then partly of just legendary actors.

The best and most talented directors - and I think it goes for people too - are the most confident in giving room to their actors and trusting them.

Twitter's a lot of work! That's the first thing I would say. There's so much pressure to be funny.
