If a dance is not danced, it vanishes. If the Dancer Dances, a new documentary by former MCDC member Lise Friedman and Maia Wechsler, confronts one of the most urgent issues facing the dance world today: how do we prevent the loss of masterworks to time? The film invites viewers into the intimate world of the dance studio. Stephen Petronio, one of today’s leading dance-makers, is determined to help his dancers breathe new life into Cunningham’s iconic RainForest (1968). With help from former MCDC members, the film tracks Petronio’s dancers as they strive to re-stage this great work, revealing what it takes to keep a dance—and a legacy—alive. If the Dancer Dances is the first documentary on Cunningham’s work since his passing in 2009.
