 This is the first film in the series to include Caucasian actors in  the original Japanese release. The scenes featuring  Brian Donlevy (qv) and Albert Dekker (qv) in the first film,  _Daikaijû Gamera (1965)_ (qv), were filmed later on a Hollywood  soundstage in much the same way that Raymond Burr (qv) was in  _Godzilla, King of the Monsters! (1956)_ (qv) as a way to help  market that film in America.
