Once you are shooting a movie, even if it's your own script, you have to let it go at a certain point. That's true for every film. It breaks up into phases where the thing that you have in front of you is the thing you have to address, and you can't worry about what you imagined a scene was going to like and that it came out differently, because that's what you have to make work.

I think that's what I love about glam-rock. It invited you to participate. It asked you to change yourself in all these different ways, or offered up all these options.

I'm not ready to give up gayness in and of itself as something unique and different. A litmus test for me for all of it was the bisexual imagination and the androgynous imagination of the Glam era. Because that meant everybody was implicated in this uncertain sense of sexual self, and it meant that everything was unstable. I guess I'm just not that interested in stable notions of identity, whatever they are.

Doing a love story as a genre, and looking at love stories in movies, and feeling like I learned stuff about that, and that it broadened my view and my idea of what I can do, and how I can work with the people around me, that was such a great, really satisfying experience.

In a way, I think Roxy Music is high camp, in a brilliant way.

It's like our go-to notion of innocent and secure mythology of American life. I was always amazed when people would come up to me and say that 'Far from Heaven' was exactly what it was like back then. [laughs] I was so disinterested in what it was 'really like' in the 1950s when I was putting the film together, I was only interested in what it was like in movies.

There is no single approach that actors take to their craft. And the best thing you learn is that you have to really listen and respect each actor's own process and own method, and that takes a kind of delicate, non-imposing patience and openness, I think, to get the very best out of the people you work with.
