Zangara plays a significant role in the background provided for Philip K. Dick's 1962 novel "The Man in the High Castle" (as well as the subsequent Amazon original series). This alternate history novel, set after an Axis victory in World War II, bases the point of divergence on the premise that Zangara succeeded in assassinating President (rather than President-elect) Roosevelt sometime in 1934. A similar Zangara-is-successful premise is used in Eric Norden's "The Ultimate Solution" (1972) and the "GURPS Alternate Earths" role-playing game's "Reich 5" alternate universe.
