Godzilla vs. Gigan

Godzilla vs. Gigan was released theatrically in Japan on March 12, 1972. It received a wide theatrical release in the United States in 1977 by Cinema Shares under the title Godzilla on Monster Island and was released in the UK by Miracle Films the same year as War of the Monsters.

Following the film's theatrical release in Japan in March, 1972, Toho commissioned Hong Kong broadcaster and voice actor Ted Thomas to produce an English language dub. As was usual with Toho's international export versions of its films, Godzilla vs. Gigan was left uncut, with the only noticeable difference being the credits and end titles being changed to English; and the removal of speech bubbles seen in the scene where Godzilla and Anguirus are talking to each other.

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.
