A large part of my filmmaking self has to do with my love of being in the cinema audience, and my relationships to what I want to see on the screen, what I have seen on the screen and what I don't want to see on the screen again.

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.

Sexuality is, of course, a great way of having a conversation between people.

I mean, even in terms of the Marvel universe, this [Ancient One character] is going on a side street into a major piazza that Marvel hasn't even been to before, because it's all about creation and not so much about destruction and forestalling destruction, it's about your mind.

What very often happens when people make films about rich people, the camera is quite mesmerised by the opulence and quite theatrical in fact.

I think that film festivals, we're very often given to understand, are about filmmakers and about films and about the industry of filmmaking. I don't believe that they are, I believe that film festivals are about film audiences, and about giving an audience the encouragement to feel really empowered and to stretch the elastic of their taste.

We also knew [ me and Ewan McGregor] that, on a practical level, if there was going to be that much sex in the film [Young Adam] - which there clearly had to be because sex is the meat and potatoes of the thing - it had to be varied for the audience, because it's important to keep the audience living in it.
