One of the wonderful things that I've always loved as an art student, what I always loved about comics, was that they are interpreted differently by different graphic artists all the time, so now film is doing that thanks to Marvel Studios.

Well you know, the comic strip [Doctor Strange]... yeah, was an Asian man, in fact, a very ancient Tibetan man living on the top of a mountain. The film script that I was given wasn't an Asian man, so I wasn't asked to play an Asian man - I was asked to play an ancient Celtic person.

In my house, a hot dog is a dog that's really hot.

I think that's true of all cinema, that's why cinema is the great humanistic art form. Whatever the film is, it doesn't matter what the film is about, or even whether it's a narrative or figurative film at all, it's an invitation to step into somebody else's shoes. Even if it's the filmmaker's shoes filming a landscape, you go into somebody else's shoes and you look out of their lens, you look out of their eyes and their imagination. That's what going to the pictures is all about.

As a performer, I'm constantly fascinated with the idea of being able to know what anybody else's experience is, and how misleading all informatives, like appearance, can be.

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.

When I say that it's taken us [with Luca Guadagnino ] 11 years to make this film, what I mean is that it was 11 years ago that we started to talk about a kind of cinema that we wanted to make together.
