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 (Fox had also produced the movie) and QM Productions (one of their few non-law-enforcement series). This show is one of the two QM shows not to display a copyright notice at the beginning, but rather at the end (the other was A Man Called Sloane) and the only one not to display the standard "A QM Production" closing card on the closing credits.
