There's that horrible-beautiful moment, that bitter-sweet impasse where you know that somebody is bullshitting you but they're doing it with such panache and conviction...no, it's because they say exactly what you want to hear, at that point in time.

He emphasised basic truths: you are not dying yet, you have to live your life until you are. Underpinning them was the belief that the grim reality of impending death can be talked away by trying to invest in the present reality of life. I didn’t believe that at the time, but now I do. By definition, you have to live until you die. Better to make that life as complete and enjoyable an experience as possible, in case death is shite, which I suspect it will be.

We were looking for someone who could get the film [Filth] made at that kind of level, with the finance we wanted, and we spoke to a lot of people. When I met James [McAvoy] in the Soho Hotel with Jon Baird, the director, he looked about ten years old. I thought there's no way he's going to be a forty-year-old divorced alcoholic cop. I thought, really lovely guy, I'll let him and John talk and see if they get on.

If I don't have something to do, I'm not the kind of person who can sit on a beach on holiday. I've got to go and check things out and see things and look at things, and have some kind of itinerary in my mind. I think that a lot of people who are, in some ways, successful are kind of like that.

These days you can't write anybody off. If anybody is a right-wing populist, you can't write them off now because that is the rising tide of our time.
