The great thing about getting older is that you learn not to care about being cool. I'm happy with who I am, I know what I like and I can't see myself changing… not for a little while, at least.

I'm not posh or common, I'm in between.

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.

It's a bit like a fledgeling duck, finding your flippers.

I have a very extreme state of mind. Things are very black or very white.

I've always got my eye on my deathbed.

I love home. I'd rather be at home than anywhere else.
