Swan Lake is divided into the black acts and the white acts. The Prince is on stage for most of the ballet, but it’s the swans audiences flock to see. In early productions, Odette and Odile were performed by two different dancers. These days, it is usual for the same dancer to play both roles. Because of the faultless ballet technique required to master the steps, and the emotional range needed to perform both the virginal Odette and the dark, seductive Odile, this challenging dual role is one of the most coveted in all ballet. Dancers would kill for the part. Ava Kirilova has reached the very top of her profession. After years and years of hard graft, pain and sacrifice as part of the London Russian Ballet Company, allowing nothing else to distract her, she is finally the poster girl for Swan Lake.
