Destroy All Planets/Fun Facts
From The Grindhouse Cinema Database
- American International Pictures titled their U.S. version "Destroy All Planets" after the success they had with the release of Ishirō Honda's Kaijû sôshingeki (1968) aka Destroy All Monsters.
- 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.
- This is the first film in the series to include Caucasian actors in the original Japanese release. The scenes featuring Brian Donlevy and Albert Dekker in the first film, Gamera: The Giant Monster (1965), were filmed later on a Hollywood soundstage in much the same way that Raymond Burr was in Godzilla: King of the Monsters (1956) as a way to help market that film in America.
