12 O'Clock High is an American military drama television series set in World War II. It was originally broadcast on ABC-TV for two-and-one-half TV seasons from September 1964 through January 1967 and was based on the 1949 film of the same name. The series was a co-production of 20th Century Fox Television and QM Productions.
