“I live in the now. That’s my philosophy, really. So the past is something you’ll have to dig up.” In this fast-moving tribute to iconic British artist David Hockney, director Lucy Walker accepts Hockney’s challenge, using a present-day interview to bookend home video, archival footage, and dozens of paintings and photographs. In the span of six minutes, we learn of Hockney’s training at the Royal College of Art in London, his move to New York, the evolution of his paintings, and the development of his interest in photography. The result is a snappy portrait of a man determined to live in the now, an artist still producing work with the same enthusiasm and energy of his youth.
