I think [Ecstasy] was a really good stab. It wasn't my strongest book or my strongest material, but they wanted to make a kinda "rave culture" movie.

The first time I went to West Virginia I was surprised by how poor it was. It was like north India, there's kids running around in bare feet. The white working class has been disenfranchised as well. It's been disenfranchised by the liberal-left as well as the conservative-right. You really have to get people right across America and Britain and Europe and the world as a whole concentrating on the economic issues that affect them, because when you don't have that, you have all these phony, racist and cultural wars, and sexist wars.

It's all been quite a revitalizing process for me, being out there in the States. It wouldn't have happened without Trainspotting.

In the cross-over, you get to a point where you realize that you've got all this genetic inheritance, and you've got all this social conditioning, but there is a point where you do have to make a choice, and that's the optimist in me: you have the freedom to make a choice about how you are going to be, and what you're going to do.

Once you've been with each other in a primal, shagging state, it's hard to talk about the weather.

I can't stand still; I find it very difficult to sit around and do nothing. I've got to have projects on the go because the devil makes work for idle hands. I've got to be going forward all the time.

Iggy Pop looks right at me as he sings the line: 'America takes drugs in psychic defence'; only he changes 'America' to 'Scatlin', and defines us mair accurately in a single sentence than all the others have ever done.
