Trivia: Godzilla vs. King Ghidorah

  • Hey, It's That Voice!: When Godzillasaurus starts being wounded by the battleships, he begins to sound like Gamera.
    • John Culkin, who voiced Maki in The Return Of Godzilla, dubs Terasawa. A few of the classic HK dubbers from the '70s films make their last appearance here.
  • No Export for You: There was a very long pause of Godzilla movies not being released over to the U.S. and it started with this one.
    • Explanation: There was a huge controversy over the footage of Godzillasaurus killing American G.I.s during the WWII sequence, along with the fact that the main villains were Westerners. This, coupled with the strained economic tensions between the U.S. and Japan at the time, resulted in the aforementioned long pause in U.S. distribution.
  • What Could Have Been: Toho was originally going to plan a remake of King Kong vs. Godzilla, but money disputes with Turner made Toho deciding to use Mechani-Kong, but Turner still demanded money to use the character. Which is stupid, because Mechani-Kong is a Toho creation.
    • A direct sequel was planned after this entry did well at the box office. This time with a King Ghidorah whose origin was more in tone with his Showa counterpart, a space monster.
    • Rather than under the sea in 2204, Tomoyuki Tanaka wanted King Ghidorah to be discovered on Venus (which he was associated with in the film 'Ghidorah, the Three-Headed Monster'). Writer/director Kazuki Omori was somehow able to override Tanaka's objections because he didn't want to make a movie about "silly space monsters." The Japanese novelization for the film ran with Tanaka's idea, in that the Futurians discovered the body of King Ghidorah partly buried on the surface of Venus and used his cellular materials to create the Dorats.
