Apart from the fact that your physical ability starts to decline, I also think someone in their fifties being childlike becomes a little sad. You've got to be careful.

People think because I can make them laugh on the stage, I'll be able to make them laugh in person. That isn't the case at all. I am essentially a rather quiet, dull person who just happens to be a performer.

Funny things tend not to happen to me. I am not a natural comic. I need to think about things a lot before I can be even remotely amusing.

I think you're bound to get a sense of any character that you play. It's not something you often do in comedy.
