“Comedy is a defense against pain. It’s something I know from the Christopher Guest movies. You can veer so close to poignancy, show something really sad, and at the same time have it be funny. There are actors like Catherine O’Hara, you can see how they veer. They veer really easily into something dark and sad. When you can do what you want with comedy like she can or like Louie, you can claim that edge then play with it however you want.”
