Hop Harrigan (aka Hop Harrigan America's Ace of the Airways) (1946) is a Columbia film serial, based on the Hop Harrigan comic books by DC Comics. The serial comprised 15 two-reel chapters with Derwin Abrahams as the director, and Sam Katzman, the producer. Columbia Pictures was one of the last Hollywood studios to continue in postwar years with the serial format. By 1947, Universal Pictures discontinued their serials, with only Republic Pictures and Columbia continuing with serials. The last serial was Columbia's Blazing the Overland Trail (1956).
