Daniel Mannix Petrie was a Canadian film, television, and stage director who worked in Canada, Hollywood, and the United Kingdom; known for directing grounded human dramas often dealing with taboo subject matter. He was one of several Canadian-born expatriate filmmakers, including Norman Jewison and Sidney J. Furie, to find critical and commercial success overseas in the 1960s due to the limited opportunities in the Canadian film industry at the time. He was the patriarch of the Petrie filmmaking family, with four of his children all working in the film industry.
