That whole Deep End experience of finding yourself with the dead body: you know you didn't kill it, but you know if you're found with it, you're gonna be done for it, so you have to get rid of it. And that's a really important nub of Young Adam — Joe knows for absolute certain that if someone comes around the corner, that's it. Nobody's ever going to believe what happened. So that has nothing to do with identity or sexuality, but that is a link. I'm just fascinated by it.

Do you want a list of what my dogs taught me? Patience, perspective, joy, loyalty, the simplicity and presence of their joy. That's a really great daily reminder, bad stuff happens, difficult stuff happens and you take them out onto the beach and you go "OK, now I see". You tell them the current political situation in the world and they go "should we go for a walk?" And you go, right, that's the correct answer.

It was an amazing performer. Very temperamental, it spent a lot of time in its trailer.

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 follow my nose. It’s as simple as that.

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.

One of the things about Derek Jarman was that he was a painter who worked alone when he painted, but I firmly believe that one of the reasons he made films was for the company. He made filmmakers of all of us, that's the truth. I don't mean he necessarily made directors, but he made us filmmakers. Because we lived in a state of mutual responsibility for what we made.
