What was so interesting about the glam era was that it was about bisexuality and breaking down the boundaries between gays and straights, breaking down the boundaries between masculinity and femininity with this androgyny thing.

I hope it's water under the bridge, but Richard Carpenter is a complicated individual, and he's also entitled to his own opinion on how his sister is depicted. The film has lived on and survived, and to me is ultimately is an affectionate celebration of Karen Carpenter. I hope that wins out in the end.

I found that with Rooney, her instincts in films was always to underplay and to sort of reduce down what was necessary to bring you in - a sense of economy, a sense of scale, which just seemed to understand the medium so well. When you see that in a younger actor, I always think it speaks to incredible knowledge. I can't exactly figure out where that comes from, that confidence to know how to be quiet.

I sort of have a dog-minded single strategy but I am a little more open to stuff that's out there, now and looking at scripts in the world and seeing if something that already exists can spark my interest and my curiosity.

When you really do feel like an alien, and you really do feel like a space creature, and you really do feel you want to experiment and dress up and be different every day, to find what looks best but never stick to one thing... Just the fact that that was offered to those kids during that time is pretty remarkable.

A refusal of nature as a model is a tradition that goes right back to Oscar Wilde.

In fact, to me it's liberating to not think of identity as some organic property that we have to find and stick to, but actually something that is constructed, or that's imposed, that we can then counter by taking a different route and re-dressing it, and then re-dressing it again, and then re-dressing it again.
