The Ghost & Mrs. Muir is an American sitcom based on the 1947 film of the same name, which was based on the 1945 novel by R. A. Dick. It premiered in September 1968 on NBC. After NBC cancelled the series at the end of its first season, it was picked up by ABC for its second season before being cancelled a final time.
