A new documentary traces the history and legacy of the world-famous Ballet Russes, and actually brings together some of the company’s original stars for the first time in decades. “The extraordinary film splices interviews with the surviving dancers with original 16mm footage of performances and nervous, gossipy backstage moments and more than 400 archive stills, gathered from the dancers’ private collections and from trawls on eBay, which produced every Ballets Russes programme from 1933-62.”
