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.

'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.

I am now obsessed with the technology of the body. I think it's the most technologically literate thing that we have.

Everyone is always telling me that I must be exhausted, but I've learned how to use my time well, and that includes holidays to recharge. I always try to give myself big chunks of time to think about what the next project is going to be.

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.

My influences change all the time they have to remain current, because they're the things that capture your imagination and make you want to go into the studio.

I like to practise. With every new piece, you make mistakes and you learn. So it's important to get on and have another go.

Misbehave more beautifully more often.

I heard Joby Talbot's Hovercraft piece for orchestra and felt its immediate physical impact - visceral, unsettling, hungry and direct. These short five minutes became our keystone to unlocking a strangely seductive score that tensions the aggressive force of the White Stripes with the enigmatic beauty of Talbot's own compositions.

I enjoy my work too much to force-feed myself with pressure.

Dancers can get to see almost everything now. When I used to go into companies to make a piece, the dancers had hardly ever seen my work. Now they can watch it on YouTube. It means they're much faster at picking up material.

I listen to music all the time, and I just choose things I like, or things that I've not used before. Sometimes I work with music that's very difficult - that I don't even particularly like, per se, but that is really complex or interesting.

Choreography and creativity - it's my matrix let's see where we can move.

I've always been just as interested in making people think as I am in making them feel, and one of the things this scientific process allows me to do is make the audience look differently at dance.

For me, choreography is a process of physical thinking. It's very much in mind as well as in body.
