There's still nearly the same amount of slavery, if not more, in the world today, as there was at the height of the slave trade.

I still find to give an interview to be difficult, as any person who deals with the press will tell you. That's why it's nice, with this one, to talk to a friend. But sometimes with a coffee and a friendly smile, I suddenly start talking without thinking about how it's going to be read.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

[Doctor Strange] is difficult, he's arrogant, but he's kind of brilliant and charming and you'd think, "Yeah, I'd want him on my head if I needed brain surgery." He's good enough to warrant his arrogance and he respects other people but not when he thinks he's right and he'll just do what he deems needs to be done when he knows or feels that he's right and the problem from humility's point of view is that he is right, he's really really good at his job.

I've done a bit of live action before but the fight sequences, the wire work and the physical regime were taken to another level [ in Doctor Strange].

When you're a kid, 'Star Trek' is a slower burn. It's funny, it's entertaining, but it also has a maturity about it - which is its universal appeal, I think.

The guy [Doctor Strange], he's like most of us, he's uncorrupted flesh from the beginning of his life, he's somebody who's not marked with original sin or any kind of crap like that. He's somebody who's come into this world and had experiences that have shaped him to the point that we first meet him. There's always got to be leverage. I think there is some clear explanation of that within this film, but potentially further down the line...for more of that to come out as well.
