My mum and dad had worked incredibly hard to afford me an education.

I thought, well, why am I giving up on my primary dream to work doubly hard, to do something as an alternative to what it really still want to?

I've never done a lead role in a film this big [like Doctor Strange], in a franchise this big. One of the reasons was, I wanted to know what the toy box was like. And it's just insane, the amount of facility that everyone gets, but the amount of artistry and craft that's brought to every aspect of filmmaking. I mean, you go to your first costume fitting and it's one of thirty. It's a myriad, but it's for a reason. There are so many incredible costumes in this.

I was thrilled with how the first series of 'Sherlock' was received. It was such great fun to film, which makes it so rewarding when something you enjoy is so well received.

I actually do mind having a photo taken because it's one o'clock in the morning and I'm off my face.

When you see a good horseman, you're unable to tell where the instruction is coming from. It's like telepathy.

It's the same thing, I think, whether it's breathing or meditation or yoga. And running is a great way of doing it.
