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 (1965), were filmed later on a Hollywood soundstage in much the same way that Raymond Burr was in Gojira/King of the Monsters (1956) as a way to help market that film in America.
