Ukrainian-born "bad boy of ballet" Sergei Polunin became the Royal Ballet's youngest ever principal dancer at age 19. But two years later - at the height of his success - he walked away from it all, resolving to give up dance entirely. Steven Cantor's Dancer tracks the life of this iconoclastic virtuoso, from his prodigal beginnings in the Ukraine to his awe-inspiring performances in the U.K., Russia, and eventually the U.S., where he went viral after David LaChapelle filmed him dancing to Hozier's "Take Me to Church." Yet beyond celebrating the raw talent and wild ambition of Polunin, whose sights are now set on Hollywood, Dancer considers how wealth and success may not be enough when it comes to finding personal and professional identity.
