The names George Balanchine and Jerome Robbins are well-known but less familiar, perhaps, is Tanaquil Le Clercq. She was one of the most remarkable ballerinas of the 20th century, a revolutionary figure whose career was cut short by polio. The new documentary Afternoon of a Faun: Tanaquil Le Clercq recounts her life and career, though it only lasted until the dancer was 26. Ironically, the first performance she ever gave for Balanchine, co-founder of the New York City Ballet, was as a character named Polio, who was left paralyzed in the performance. Tani’s incredible will comes through here, in reflections from dancers, in recreated interviews, and through archival footage. Although she never walked again as a result of polio, LeClercq remained a towering figure in the world of dance, and this is a fine testament to her legacy.
