This is a very nice short made by producer/editor Tulip Tappenden at Derek Boshier’s Los Angeles studio in 2013:

It includes many of the works featured in the forthcoming monograph Derek Boshier: Rethink/Re-entry, which is published by Thames & Hudson in October and features a foreword by David Hockney.
