Alla Kovgan traces the career of Merce Cunningham, a Cornish alum who emerged from a struggling dancer in New York to a visionary modern choreographer. In addition to interviews with those who knew him and a peek into his gorgeous love-letter correspondence with his longtime lover and collaborator John Cage (e.g. "I have nothing to say, and I am saying it. And that is poetry as I need it."), this documentary has some great excerpts of Cunningham's work—including a piece performed in the middle of a forest.
