I think it's the responsibility of a major opera house not only to cultivate debate and get people thinking, but also to be interfaced with things that challenge them. To challenge its audience and not just deliver things that they know, even though some of those things are wonderful.

I always try to keep a little bit of space in the year to work with other people. Because I love doing musicals, films and plays - projects where I'm not in charge, where I've got somebody else telling me what to do and I have to work with their vision.

Unlike a lot of choreographers, I don't always start with the music. I often start with a visual artist, and then find music that fits the world of that visual artist.

Entity' is not about science. The process behind it may dictate the nature of the piece, but it's not like a dance about Einstein where I'm trying to convert his ideas into movement and communicate that to an audience.

The big pay-off was to work as an artist and gain some shred of respect from your friends, who were also artists. But there was never any notion that you could make a living out of art. On the rare occasions you had a gallery show, and sold a little work, well, that was just gravy.

I loved the world of imagination.

My birth mom has certainly not lived a life of means in any stretch of the imagination, nor does she want to.

Even in the Pixar and DreamWorks animated movies, there are themes that could be taken into an adult area very easily. 'Zootopia,' I think, is the closest so far; I love that movie because they really did push the envelope as far as the ideas and writing of an animated film for families.
