I think it's necessary to identify with anything - with any character you play, there's got to be something in common, so you can link up to that person, even if it's like one tiny thing. But it's equally fun to play somebody completely different, and trying to find what that thing is to make it.
I feel more confident in being able to be funny if I'm comfortable with the people I'm around. When you're friends with them, it just makes it all the better. Plus, shooting a movie, you're sitting on your ass for hours at a time, so if you have somebody there to mess around with and have fun, then it's great.
'Party Down' is the most fun I've ever had working in my life. We shoot 10-episode seasons and we shoot it in 10 weeks, so it's very brief: 4-day episode shoots. You never get sick of anybody, and it never feels like a drag. It's way, way, way too short.
