Sad news to hear of the death of John Donald Francis Black (December 30, 1932 – November 29, 2018), who was a major contributor to the success of the original Shaft.
Ernest Tidyman had adapted his own novel in a literal fashion for the original screenplay. Gordon Parks drafted in Black, a very experienced TV and screenwriter, to tighten up the plotting and dialogue. The result was a co-writer credit. The movie was shot using Black’s revision as its basis. Gordon Parks added his own magic and with Isaac Hayes’ score and Richard Roundtree’s assured starring role debut, it became an unlikely hit. MGM was saved from bankruptcy and the Blaxploitation genre took off in Hollywood. His prolific career in TV (including Star Trek, Laredo, Hawaii Five-O, etc.) demonstrates the breadth of his skills.
Black died peacefully of natural causes at the Motion Picture Hospital in Woodland Hills, California. A statement from his publisher Jacobs/Brown Press on behalf of his widow, Mary, can be accessed here.
