American adaptation
The 9 Super Giant films were purchased for distribution to U.S. television and edited into 4 films by Walter Manley Enterprises and MedallionFilms. The 2 original Japanese films which went into Invaders from Space were 48 minutes and 39 minutes in duration. The two films were edited into one 78-minute film, resulting in a total of 9 minutes being cut from the two films during the re-editing. Also, most of the original music was replaced by library cues.
