I remember when I first started to be photographed, people couldn't understand how it was possible to go around with no eyelashes, no eyebrows. Now it's much more accepted for people not to wear eyelashes or lipstick or whatever they do, but then it was quite freaky. Um, a kind of boiled look.

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.

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

[My work] just develops and develops, and I'm very nicely served by the universe: just as I'm ready to take the conversation further with myself, some other individual pops up, like David McKenzie did, with this idea of making this film [Teknolust], and provides exactly the leap to the next adventure.

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.

There's no need there to sit with the filmmaker for 11 years to develop the script, or go round the world raising money.
