After an initial career as an actor, MacTaggart worked as a producer for
BBC Radio in
Scotland before moving into television. He relocated to London around 1961, at the request of his friend, scriptwriter
Troy Kennedy Martin. MacTaggart aimed to break down the use of
naturalism in television drama: "We were going to destroy naturalism", Kennedy Martin once said, "if possible, before Christmas". In a television career of almost 20 years, MacTaggart wrote, directed or produced nearly 100 plays or episodes. ==Legacy==
