American International titled their U.S. version "Destroy All Planets" after the success they had with the release of Ishiro Honda's Destroy All Monsters under the title "Destroy All Monsters".
This was Kôjirô Hongô's final appearance in the series.
This was the first film in the series to use flashbacks from the previous Gamera films as a way of saving money on the production. In this film, the flashback sequence lasts approximately fifteen minutes.
