Royal Ballet star Silvie Guillem is almost 40. She’s “difficult, it is said, known for being arrogant and argumentative. She stormed out of the Paris Opera following fights with Rudolf Nureyev and took off for the Royal Ballet, where she had more rows, this time with Kenneth MacMillan. She said no to an amazing number of parts and, even where she said yes, she refused to do them in the usual ways or wearing the costumes that other people provided.”
