'At its greatest, there's an animalism about ballet. There is a spirit at the heart of it, a life that comes through the form that can be extraordinary. I was amazed at how hard the dancers work to achieve that,' he says.
Though he had considered creating the movement as well as directing, he ended up creating 'a choreographic text' with choreographer Radu Poklitaru.
'We had to find a way of choreographically telling the story and the music is key to that. Prokofiev's score is one of the most powerful in the world and what it does is force you to see the darker side of the action as well as the light side.
It's odd, but there seems to be a move away from narrative ballet and I think that's a shame. Dance is a very powerful way to tell a story.'
