The first time we did cavalry charge I was so breathless with excitement I nearly fell off the horse. I actually saw stars in front of my eyes and thought I was going to faint. The second time I had a bit more control but was still giddy with excitement. And the third time I was an emotional wreck. I had to really try hard not to cry.

The story [in 12 Years a Slave] serves as a metaphor for the fear of having your family taken away, and for being abused in such a horrific way. I lost it a lot of times watching that film, particularly when seeing the grace of the man when he finally makes it back home aged, changed, forever brutalized, and yet he apologizes to his family for his long absence. That was such a profoundly moving moment capturing the triumph of dignity over the disgraceful behavior of those involved in the slave trade.

One of the first roles I had on stage was with a brilliant director in a brilliant play with a brilliant cast, but I just couldn't find my way into the heart of the character. I found myself straining a lot. When it started. I felt lost. That was the Eugène Ionesco play Rhinoceros. I don't think I was prepared for that. I don't think I had the full tool kit to do it justice. It's a very difficult play, it's an extraordinarily difficult part, and I never felt I really got it right. Far from it. To a degree, Hamlet was the same.

I've been broody since I was 12, but I can't just get anyone pregnant. It has got to be the right person.

I suppose my bodily proportions are quite flattering. I'm ripped, doing something I wouldn't normally do with my body, or having done to it, involving Watson.

[ Stephen Strange] is less strange than other characters I've played. He's lost the power to love, which doesn't make him a nasty person. I just think he's closed-off.

I did a lot of acting at school and university, then I went to drama school. It was quite a normal route.
