There are times when I consciously give the character something physical - a walk, the way he sits, how he talks, or his lack of physicality, which is like a physicality.
When I was in improv workshops or doing stand-up or writing comedy with others, or just doing comedy, I just laughed. Funny was funny; I loved to laugh. I always liked people I found generally funny.
Will Ferrell makes me laugh a lot when he gets out there and gets crazy.
I choose not to be at the whim of others. I want to be at my own whim.
Weirdly, for someone who wanted to be funny, I didn't like a lot of attention.
Unpredictability means what it means. I don't know how you define it. It is what it is.
