Every actor is riddled with insecurity, of course. But weirdly, I don't really find that I'd be daunted with taking on roles or anything.

I value being able to go into a record shop and people leaving me alone.

Benedict (Cumberbatch, who is playing Sherlock) looks amazing. He's still got a Sherlockian silhouette, with a large overcoat, but in a classic cut. Watson dresses with an urban elegance, a touch of old school dashing, giving a feeling of both the military and medical profession. I suppose it's something they have in common as well. They're a bit metrosexual.

You don't want your children to look at you like you are anything special other than their dad.

However happy the director is, I have to be okay with it. I'm pretty strict with myself, about throwing things out or trying to be true to whatever the situation dictates.

I like things that are simple, such as an alarm clock.

I love that pre-mod jazz look of the late Fifties, the Steve McQueen style that influenced the British modernists.
