Ulay is a conceptual artist whose photography pushed boundaries, and whose love affair with Marina Abramovic produced some of the best pieces of performance art. Diagnosed with cancer shortly after agreeing to film the documentary, Ulay's illness informs Project Cancer, which is part-retrospective, part-visual document of the year he believed could be the last of his extraordinary life.

Performance artist Marina Abramovic prepares for a major retrospective of her work at the Museum of Modern Art in New York.
