I don't make much distinction between being a stand-up comic and acting Shakespeare - in fact, unless you're a good comedian, you're never going to be able to play Hamlet properly.
It may be my rather puritanical upbringing at odds with my inborn laziness that makes me feel guilty at the end of the day, unless I am able to point at some achievement. But this need be no more impressive than cooking a meal or going for a long walk.
I've always longed for the theatre and acting to be popular. No actor wants to play to an empty house. We only do it for an audience. The more the merrier. I don't make any distinction between a popular TV series or blockbuster film and doing Shakespeare. They're different, but as long as the material is good and the intention is honourable, it's all the same to me.
I'm not experienced enough, or certain enough of my acting on the screen to say to a director, "You are wrong, I am right. I will only do it this way." I could never feel that, I wish I could be absolutely certain. But on the stage, it's different. I know where I am on the stage.
