In 1977, Mel Maron's Cinema Shares International Distribution purchased the North American rights to Godzilla vs. Gigan and released the film as Godzilla on Monster Island in the U.S. Rather than going to the expense of dubbing the film again, Cinema Shares utilized Toho's English dub. Aiming for a "G" rating from the MPAA, the company's editors removed three instances of blood from the monster scenes and muted the phrase "You're a hard bitch" on the soundtrack. Following the theatrical release, Godzilla on Monster Island entered television syndication.
