I've been doing interviews for years, and in all that time, I've virtually never read one and gone, 'Yep, factually and tonally that's exactly what happened.' Pretty much never.

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.

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.

I hate the fact that so much of our life is computerised rather than mechanised.

I think if you were known for playing something other than being a nice guy then people might be a little less likely to take liberties with you. If you are Ray Winstone, and people have seen you kick a few people to death, then they are a little less likely to approach you or whatever.

On the one hand, we're constantly told about recycling and cutting back, and on the other hand we have to buy the next gadget that comes along three weeks after the last one you bought. It's absolutely insane. We've been suckered into buying and buying and upgrading and upgrading. We're being given two very different mantras at the moment, I think.

I like the idea of not everything happening between two human beings to be everyone's property.
