We went to an early screening of Cunningham, a film directed by Alla Kovgan, about the life and work of Merce Cunningham, using documentary film footage, quotations and reconstructions of original dance sequences in an astonishing and literally three-dimensional film biography (one watches it through 3-D glasses). I had very little idea of Cunningham’s life – his relationship to John Cage, the way his belief in radical pure movement and abstraction was appreciated and, in the 1960s, supported by Robert Rauschenberg and Jasper Johns, with Rauschenberg involved in making sets for the company. All of this is shown, but in a way which is brilliantly inventive and creative, not at all a conventional documentary. Distributed by Dogwoof and coming to our screens in February. See it if you can in 3-D.
