I look like the man in the moon.

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.

Not all Peter Greenaway's stuff is sequential, narrative story. Some of it is like an art installation and I'm not particularly interested in being in an art installation to be honest. I'm interested in the story.

I can spot someone with similar fashion sense to me a mile off.

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.

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.

True heroics, obviously, is not the absence of fear, but having that fear and doing something anyway.
