I can't impersonate someone. That is not what I do. I can only take someone's essence and create a character out of that.

I did not enjoy Cambridge. But I shouldn't blame Cambridge alone. I wasn't ready for university or for the wrench of leaving home. It was a big cultural shock.

At Cambridge, it was the weirdest culture. Everyone pretended they didn't do any work, yet it was so competitive.

Getting to travel around the world and go to glamorous locations is certainly not what I had as a kid.

Acting is a career without a safety net, because it's not like a professional job where every year you hope to be promoted, and get a sense of career stability. There is never any stability in this business.

I really enjoyed working with Daniel [Craig], because he's a brilliant actor at the top of his game. That gave me an opportunity to learn from the best, which is what you're always looking for as a performer in order to grow and get better at your craft. It was also great because he was so nice and incredibly supportive, because it really was an intimidating experience for me. He sort of held my hand and said, "We're in this together and we'll get through it together." And he did look after me.

I'd like to believe that I would be able to give in the same way Mandela did, but in reality, I don't know whether that is true. It is much more likely that I would be left with an immense sense of injustice and immense desire for revenge.
