Hey, It's That Voice!: People familiar with the DCA cut of Rodan will instantly recognize the voice of Keye Luke, who provided the voice of Shigeru in that film.
George Takei as well providing his voice as several male characters in the film.
What Could Have Been: Interestingly enough, Godzilla Raids Again wasn't intended to be merely dubbed and distributed. It was going to be called The Volcano Monsters where Godzilla would be just a Tyrannosaurus Rex and Angurirus to be an ankylosaurus (how they are gonna explain a T-Rex that clearly looks like Godzilla is beyond us). Godzilla (or rather the T-Rex), was to fight the ankylosaurus and move to the North Pole to lay its eggs. While Toho decided to help by sending new suits and made a catalog of the production, the American company went bankrupt and the suits disappeared. So now, The Volcano Monsters was ultimately cancelled. This explains why it took a whole 3 years on why it wasn't released in form. Eventually, the film ended up being called, by the massive face-palming of Steve Ryfle (and his fellow commentators) and fans everywhere, ''Gigantis The Fire Monster".
