Background and Trivia

  • Toho submitted the movie to the US copyright office on April 22nd, 1988. The titles used were Godzilla vs. Megalon, the international title, and Godzilla tai Megaro, a hybrid of the Romaji title.
  • Played at the Toho Champion Festival in Spring of 1973. It was featured alongside Prominent Youth! (1973) and Panda Go Panda: The Rainy Day Circus (1973).
  • Director Jun Fukuda wrote the screenplay, created based on Shinichi Sekizawa's treatment. This was because, due to the tight schedule, Sekizawa did not have enough time to write a full script, requiring Fukuda to step in. Mentioned in Japan's Favorite Mon-Star (ISBN: 1550223488).
  • The entire production, from planning to its completion, took about six months. Cited in Age of the Gods (self-published).
  • Special effects director Teruyoshi Nakano has been quoted saying he feels the entire shoot for the movie was "probably three weeks." Noted in Japan's Favorite Mon-Star (ISBN: 1550223488).
  • The first screenplay, submitted in 1972, featured a longer title of Godzilla vs. Megalon: Operation to Destroy the Undersea Kingdom (ゴジラ対メガロ兄弟 海底王国全滅作戦). A second script, drafted on September 5th of 1972, had an even longer title of Insect Monster Megalon vs. Godzilla: Operation to Destroy the Undersea Kingdom (昆虫怪獣メガロ対ゴジラ 海底王国全滅作戦). This name is noteworthy for giving Godzilla second billing after Megalon, something that hadn't happened since Mothra vs. Godzilla (1964). While this name stayed for the third draft, ultimately a more streamlined title of Godzilla vs. Megalon was selected.
  • The characters Goro Ibuki and Rokuro "Rokkuchan" Ibuki belong to a big family, noted as the 5th and 6th brothers respectively with Rokkuchan being the youngest of his siblings. Brought up in Age of the Gods (self-published).
  • Actor Katsuhiko Sasaki, who plays Goro Ibuki, notes that the scene of Rokuro Ibuki using his dolphin pedal boat was filmed at Lake Motosu. He recounts this being December of 1972, and as a result was quite cold. To mask this, director Jun Fukuda had the older actors Sasaki and Yutaka Hayashi drink whisky to help minimize the visibility of their breathing in the cold. This is brought up in the DVD commentary on Toho's release.
