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.

I feel that TV and film feed off each other well. It's more in the perception of the viewer than it is of the actor.

I've been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.

There's no shame in stealing - any actor who says he doesn't is lying. You steal from everything.

I have an appetite for the normal in my life, as well as the abnormal.

I think now with fundamentalists, people who treat belief with a total lack of humor or empathy for any other viewpoint than their own - they, to me, are the enemy. And those people are born out of desperate extremes.

I realised quite early on that, although I wasn't trying to make a career speciality of it, I was playing slightly asexual, sociopathic intellectuals.
