on the set. In some European markets, the film was retitled as Marijuana and omitted the communist angle, making the villains drug dealers, instead. This was achieved entirely through script changes and dubbing. The film's publicity slogan was: "He's A Go-Get-'Em Guy for the U.S.A. on a Treason Trail That Leads Half-a-World Away!" James Arness, who played the title character's sidekick in the film, later played a police officer named Jim McClain in the short-lived 1980s TV series "McClain's Law". No explicit connection between the movie and the TV show was ever acknowledged, but Arness' character was addressed as "Big Jim McClain" in a scene from the series' movie-length pilot.
