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.

The awful lesson of history is that we too often ignore people, just because they're foreigners or different from us.

My massive motivation in life is to make parents proud. But even that has to stop at a point.

I think with any characterization there's a point where you empathize, no matter how much of a deviance his or her actions may be from your understanding of humanity.

It's an interesting arc. You start with a character [Doctor Strange] who's likeable and charming but very arrogant and distant. He's funny but you can see there are massive holes in his life. It's a very painful transition and all that he becomes is tested so quickly and violently.

If people ask, 'Are you Sherlock Holmes?', it's horribly naff, but I say, 'I'm not, I just look a bit like him' - which is how I feel. There are bad attributes of his that I really don't share!

Enjoy the journey of life and not just the endgame.
