'Frankenstein' was all about the idea that, through electricity and the destruction of night, man creating light and darkness, we took on god-like powers and then abused them like gods, and we are only men. That's a story about man making a man in his own image. The inversion of natural order.
I got live tweeted once by someone who was opposite my home in some rented accommodation. He was actually describing on twitter what I was doing. 'I took a shirt off, I went to the window, I put a shirt back on... ' And I've got blinds in my flat!
People's hands fascinate me. It's tempting to look at a businessman's left hand and see if there's an indentation from a missing wedding ring. Or maybe there's a tan line and the skin is pressed down where's he's worked a ring off his finger.
A woman who knows that she doesn't have to get all decked out to look good is sexy. A woman who can make you feel smart with her conversation skills is also sexy. I believe the sense of humor is important.
I had a real yearning to make use of the opportunities I had at school. When I heard about the gap year of teaching English at a Tibetan monastery, I knew I had to do something about it really quickly, otherwise it was going to get allocated.
I'm not confident in social situations; just going up to someone in a bar and saying 'Hi' is going to be even more difficult because they won't know the real me. They will just know me as a fictional person I play on the screen.
We're living through a time where we are fighting wars fostered by politics, admittedly not on the same scale as the First World War, but with equally tragic realities for our soldiers and their families.
Do awards change careers? Well, I haven't heard of many stories where that's the case. It's a fun excuse to meet colleagues and celebrate people who've done well that year in certain people's eyes, and it's nothing more than that.
'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.
The number of people my age, younger now, a whole generation younger, who are fiercely bright, over-educated, under-employed and who are politicised and purposeless really upsets me. It's soul-destroying.
When you start getting jobs, and see your mates from drama school, you don't really want to talk about it, because you have this innate sense of guilt that it's not fair that others aren't doing exactly what you're doing. I do have that.
There's a huge raft of roles that actors in our culture perform, and you can see any one of about three Hamlets in a year. It's not something to be completely daunted by.
To get a horse to hit a mark without a rider, to get it to stand up, to get it to rear, to get it to pick up a bucket and bring it over is amazing. It's hard work and very rewarding but can be dangerous.
My first agent dissuaded me from calling myself 'Cumberbatch.' I had six months of not very productive time with her, so I changed agents. The new one said, 'Why aren't you using your family name? It's a real attention-grabber.' I worried, 'How much is it going to cost to put my name in lights?' But then I decided that's not my problem.
It's difficult because nothing's preordained by plan and you can't control it. That's one of those joys and thrills and nerve-racking realities of being an actor. A lot has to do with luck, no matter what your talent or contribution can be.
