Losing yourself in the character opens you up in a way that no amount of precise preparation can.
I actually like character work, so for me, generally speaking, I enjoy it. It's a little bit more of a comfortable suit you put back on. You can explore it and have fun with it and push the limits of it.
I'd like to say that parody is a celebration of a person's specific characteristics, as opposed to mockery.
Writers tend to hate recurring characters; there's this writer snob thing about it. But I don't have that. I feel like the challenge is always to find a cool and innovative way to do it and, obviously, to not repeat your jokes.
I'm happier than I've ever been. SNL is one of the only places you can both act and create characters for a living.
