This film [Doctor Strange] kind of takes that everyday boring reality and really bursts it wide. So we talked a lot about that. In many ways there's something very practical about this world, the Kamar-Taj. It's - You know, we all look like samurai warriors, but actually there are iPads everywhere and there's a feeling that it's a practical possibility for this modern world that the Doctor Strange universe is functioning, and that we know it and it's around the corner for all of us.

I'll tell you one thing, and this is banal to say because it just makes it sound like it's all planned, and nothing is planned at all. But one link is with The Deep End, and one link is that I'm making a film later on that revolves around the relationship between an innocent party and a dead body.

The work is different in the sense that I haven't had to travel round the world raising money, or work from the genesis of the project. But the collaboration feels clear always, it's sort of my drug, I'm in it for the conversation. The conversation's the most important part of it.

The people I'm working with tend to be people I know, who are my friends, and I like hanging out with them. There's nothing better than making a long-term project with your friends. It's just dreamy.

For me, sex is a refraction of the thing about identity. In the sexual contact, which is usually - but not exclusively - between two people, you do retain separate people.

I am the only living person in the English speaking world who didn't have the Narnia books as a child.

I have this very strange relationship with my work, which is that it's like a conversation between me and it.
