David Diliberto (born April 29, 1970) is an American filmmaker. As a longtime collaborator of Joel and Ethan Coen, Diliberto was a part of several innovations in post-production technologies. He supervised the first Digital Intermediate on a full feature with the film O Brother, Where Art Thou?. The Coens' stylized film noir, The Man Who Wasn't There, provided analog hurdles rather than digital ones when several prints of that black & white film burned in projectors. The special film stock used for the movie had a high silver content and had never used for printing or projection. Trailing the industry abandonment of old-school film editing techniques, David configured Final Cut Pro systems that could emulate the Coens idiosyncratic method of editing in a digital realm. Intolerable Cruelty was the first major studio feature edited on Apple Computer's Final Cut Pro software.
