Born in the outer London village of Cheam, Cunliffe became interested in drama while attending Tiffin School in Kingston upon Thames.
This interest led to his winning, at age 16, a Queen's Scholarship to the Royal Academy of Dramatic Art (RADA) after which he worked for several years in repertory theatre around England until he became, in his mid-twenties, one of Granada Television's directors during Coronation Street's earliest years.
Over the succeeding decades he accumulated a very large body of work as a director, producer-director or executive producer, much at Yorkshire Television,[1] in such programmes as 1962's Before My Time, 1965's The Man in Room 17, the 1969 and 1970 programmes, Great Performances, Ryan International and Dr. Finlay's Casebook, 1971's Kate, 1972's The Onedin Line, 1973's Warship, 1974's Fall of Eagles and Good Girl, 1975's The Main Chance, 1976's Hadleigh, Forget Me Not and Dickens of London, 1977's Raffles and Beryl's Lot, 1979's Flambards and The Sandbaggers, 1981's The Good Companions and Get Lost!, 1982's Airline and ITV Playhouse, 1984's Sorrell and Son and Killer, 1985's The Beiderbecke Affair, 1986's Love and Marriage, 1989's A Bit of a Do,[2] 1995's Oliver's Travels, 2001's Victoria & Albert, 2006's The Shell Seekers and many others.
