The War of the Gargantuas (フランケンシュタインの怪獣 サンダ対ガイラ,   Furankenshutain no Kaijū: Sanda tai Gaira, lit. Frankenstein's Monsters: Sanda Against Gaira) is a 1966 tokusatsu kaiju film produced by Toho and a loose sequel to Frankenstein vs. Baragon. It was released to Japanese theaters on July 31, 1966.


One night, a fishing vessel in the waters off Japan found itself under attack by a Giant Octopus. The creature wrapped its tentacles around the ship and began to crush it until a giant green monster appeared from underwater and attacked it. The giant, Gaira, overpowered the Giant Octopus and threw the creature into the water, prompting it to retreat. Gaira then destroyed the ship himself and devoured the helpless crew. One sole survivor from the attack was found, and during questioning he claimed that the ship was attacked by "Frankenstein." Dr. Paul Stewart and his assistants Akemi Togawa and Yuzo Majida became concerned that the monster that attacked the ship might be none other than Sanda, the Frankenstein spawn they raised at their laboratory years ago before he escaped to the mountains. Akemi asserted that Sanda was not capable of committing such violence, and so the three scientists set out to find evidence.

Meanwhile, Gaira came ashore at Haneda Airport and terrorized the citizens there. Gaira smashed the airport terminals, stepped on planes, and devoured helpless people. However, when the sun appeared through the clouds, Gaira ran back into the ocean. The JSDF quickly developed a plan to stop the creature, a new space-age weapon dubbed the Maser Cannon. When Gaira appeared in the wilderness one night, the JSDF ambushed the beast with their Maser Cannons and blasted him with countless volts of concentrated electricity. Gaira was almost killed, but his brother Sanda appeared through the forest and came to his aid. Sanda waved the JSDF forces off and carried his brother off to his mountain home. After this, Dr. Stewart concluded that Gaira must be another Frankenstein spawn like Sanda, having regenerated from some of the giant Frankenstein monster's immortal cells. However, while Sanda was lovingly raised by humans, Gaira grew up underwater in a hostile environment and became a vicious man-eater.

While Gaira was recovering in the mountains, Sanda made a horrific discovery when he saw his brother attack and kill a group of hikers. Realizing his brother was an enemy to humanity, Sanda attacked Gaira, driving him out of the forest. When Gaira appeared in Tokyo, Sanda took it upon himself to stop him and went there as well. Akemi pleaded with Sanda, whom she had raised like a son, to not go to Tokyo and risk being killed by the JSDF or Gaira, but Sanda continued on. When Sanda found Gaira in Tokyo, he pleaded with his brother to simply leave and avoid fighting, but Gaira attacked him. The two Gargantuas battled across Tokyo and eventually their battle spilled out into Tokyo Bay. While the Gargantuas battled in the sea, an underwater volcano erupted, causing both Sanda and Gaira to be pulled into molten magma flows and disappear. Dr. Stewart sadly told Akemi that both monsters were likely killed and that the magma completely destroyed all of their cells so they could never regenerate. Sanda's sacrifice was not in vain however, as he ensured that humanity would forever be safe from Gaira's reign of terror.

Theatrical Releases

U.S. Release

American The War of the Gargantuas and Monster Zero double bill poster

The War of the Gargantuas was released in the United States by Maron Films in 1970 as part of a double-bill with Monster Zero. Dialogue was dubbed to English. All mentions of "Frankenstein" were removed, and Sanda and Gaira were simply referred to as "Brown Gargantua" and "Green Gargantua," respectively. The U.S. version contains nearly ten minutes of alternative and extended footage filmed at Toho in agreement with UPA and Henry G. Saperstein, some of which serves to establish Russ Tamblyn's character earlier in the film's story. The film's music score was altered significantly, with all pieces containing Akira Ifukube's "Operation L" leitmotif replaced with a library track by American composer Philip Green entitled "Terror Hunt," or other pieces from the film. In addition, cues from Monster Zero were also supplemented.

In 2017, Toho's international English export dub for the Japanese cut of the film became available to stream via STARZ and FilmStruck, after an acquisition by Janus Films.

  • During the film, several ambiguous references are made to the film Frankenstein vs. Baragon, but the only direct link between the films is the term "Frankenstein," which appears in the Japanese title and is used to refer to the Gargantuas ("Frankensteins") in the original Japanese dialogue. Due to dialogue referring to the monsters as "Frankensteins," Russ Tamblyn had to re-dub his dialogue for the American version of the film, which removed all references to Frankenstein.
    • Additionally, Kumi Mizuno's character in this film, Akemi Togawa, is very similar to her character Sueko Togami from Frankenstein vs. Baragon, leading some to believe she is in fact reprising the role.
  • The War of the Gargantuas is referenced in the beginning of the 2002 Godzilla film Godzilla Against Mechagodzilla, and stock footage of Gaira from the film is shown. Supplementary materials for the sequel to Godzilla Against Mechagodzilla, Godzilla: Tokyo S.O.S. reveal that The War of the Gargantuas is part of the continuity of the two films, along with several other non-Godzilla films from the Showa era.
  • This film marks the first appearance of the Maser Cannon in a Toho film. The Maser Cannons would go on to become famous recurring military weapons in Toho's Godzilla films over the next several decades.
  • The American producer of the film, Henry G. Saperstein, had reportedly planned to make a collaborative Japanese-American Godzilla film, possibly featuring a Gargantua battling Godzilla.
  • The original ending of the film was to not only have Sanda and Gaira swallowed up by the underwater volcano, but the lava was to have spread to Tokyo where it was to destroy the city as well as the remaining cells of the monsters; cited in an interview with director Honda in Guy Tucker's Age of the Gods: A History of the Japanese Fantasy Film.
  • Sanda and Gaira re-appeared in Go! Godman Episodes 16 Godman vs. Sanda and 17 Godman vs. Gaira as well as in Go! Greenman Episodes 31 Greenman vs. Sanda and 4 Greenman vs. Gaira. Gaira later made an appearance in the 2008 Go! Godman movie.
  • Quentin Tarantino based the fight between Uma Thurman and Daryl Hannah in Kill Bill Vol. 2 on the final battle from The War of the Gargantuas. He showed his copy of the film to both actresses and told them he wanted it to be "The War of the Blonde Gargantuas."
  • For the trailer of the upcoming TLC show Inedible to Incredible, music from the American version of The War of the Gargantuas plays briefly in the background.
  • During the 2012 Oscars there was a segment called "First Movie Moments" where famous actors describe the first movie they remember seeing. Actor Brad Pit stated that the first movie he ever saw was none other than The War of the Gargantuas.[2]
  • In the trailer for the movie, Sanda and Gaira have roars which differ from those in actual movie. One roar is a higher pitched Rodan roar and the other is Varan's roar mixed with King Kong's. These roars would go on to be used for the Ultra kaiju Antlar and Chandora, respectively.

Did anyone else watch the American version of War Of The Gargantuas first and get confused by how they make no relations to Frankenstein vs. Baragon? I sure did.
