From Bradford and back again, Hockney's career saw him travel to London, New York and California and his travels very much influenced his work. Now 78, the artist looks back at his life giving viewers a peek into his life and work. Director Wright was also behind  "David Hockney: Secret Knowledge," a 2002 documentary for the BBC focusing on the Hockney-Falco thesis. Check out the trailer for ''Hockney'' here.
