The further you get away from yourself, the more challenging it is. Not to be in your comfort zone is great fun.

I am very flattered. I have also become a verb as in "I have cumberbatched the UK audience" apparently. Who knows, by the end of the year I might become a swear word too! It's crazy and fun and very flattering.

I'm always playing characters with intellects profoundly superior to mine. That's great fun, even though it's as much a fantasy for me as for the people watching me.

There are moments when, like all of us, you get a bit self-conscious and you'd rather not be living any of your day in public. Those are the awkward times, but you've got to have fun with it.
