This 12-part Buck Rogers movie serial was launched in 1939. It starred Buster Crabbe, who had played the role of Flash Gordon in the serials "Flash Gordon" and "Flash Gordon's Trip to Mars" prior to "Buck Rogers". Constance Moore played Lieutenant Wilma Deering, the only woman in the film, and Jackie Moran was Buddy Wade, a character who did not appear in other versions of the Buck Rogers franchise, but who was clearly modeled on the Sunday strip character Buddy Deering. Anthony Warde played "Killer Kane", Buck Rogers' enemy; this was the only time that Warde, who usually portrayed evil underlings in serials, played a lead villain. Korean-American actor Philson Ahn, younger brother of noted actor Philip Ahn, played Prince Tallen, a Saturnian native who befriends Buck Rogers.
