Dogora the Space Monster, released in Japan as Uchū Daikaijū Dogora (宇宙大怪獣ドゴラ, lit. "Giant Space Monster Dogora"), is a 1964 Japanese tokusatsu science fiction film produced and released by Toho Studios. Directed by Ishirō Honda and featuring special effects by Eiji Tsuburaya, the film starred Nobuo Nakamura, Akiko Wakabayashi, and Hollywood actor Robert Dunham. The film tells the story of a huge jellyfish-like creature from space that attacks Japan.
The film was released straight to television in the United States, in the winter of 1966 by American International Television as Dagora, the Space Monster.
The gangsters bring Mark Jackson to their boss and find a bag containing the stolen diamonds. However they too find out that they are fake and keep him as a prisoner but outwits them and escapes. The gangsters are then given word of a shipment of raw diamonds will arrive in Yokohama.
Meanwhile, Inspector Komai escorts Masayo to her home. Along the way they meet Kirino (Hiroshi Koizumi), Masayo's brother who works at the Electric Wave Laboratory. They witness a strange invisible force suck up coal into the sky from a nearby the factory as well as flaming sparks from the clouds. They meet back with Dr Munakata who tells them that the flaming sparks might be from some form of carbon.
Later, the professional thieves took advantage of this ripe opportunity and attempted a heist on an armored car carrying the raw diamonds. But a nearby coal truck passing by is lifted off the ground by some unknown force and disappears into the atmosphere and is dropped back down to the ground. Unfortunately for them, they were fooled and escaped with nothing but candy.
The police came to learn of the mysterious events of the armored car heist. Inspector Komai tells them of the possibility of a creature that caused the coal truck to list up in the air, but no one believes him. He is then called by Masayo a that Mark Jackson is at Dr. Munakata's house. Komai and the police surround the house to catch him. But he reveals himself that he is an investigator dispatched from the World Diamond Insurgence association to find out what has been steeling diamonds worldwide. Just then Masayo's brother comes in and tells them that the identity of the monster was reported from the Space Planning Committee at the U.N. that the monster is a space cell that has been mutated by massive amounts of radiation from the satellites. Suddenly, Dogora appears and eats its way through Dr. Muanakata's safe to eat the diamonds inside.
The creature from outer space is deemed to be the culprit, an alien beast that draws its energy from carbon-based minerals. Dr. Munakata, confident in a remarkable scientific discovery, left for the coal mines near northern Kyushu, where it was proposed that the strange being would make its next appearance.
Mark Jackson also took leave for Kyushu, as the realization was finally made that the candy recovered at the heist was likely his doing. It was probable that he had, in truth, absconded with the true gems. Hamako (Akiko Wakabayashi), one of the gangsters responsible for the failed heist, prepared to double-cross her comrades and retrieve the diamonds for herself.
As Dr. Munakata arrived at Dogora's next likely target, unidentified objects began to show on radar. A swarm of wasps was attacking Dogora in retaliation for the disturbance of their hives in the mines, and as they attacked, solid crystal sections of the monster began to fall to the city below.
Over Dokaiwan Bay, as night fell, evacuation orders were put into effect as the jellyfish-like monster began to descend from the sky. The self-defense force fired, to no avail. The monster continued to absorb carbon-based materials wherever they could be located, and the abomination even destroyed the Wakato Bridge in the process. The military continued to unleash their artillery at the alien creature, and succeeded in momentarily silencing their foe. Unfortunately, the creature was only undergoing mitosis.
It is later found out that when Dogora is stung by the wasps, the venom causes a chemical reaction that crystallizes the space cell. Analysis of the crystallizing effects of the wasp venom on Dogora at the Medical Substance Laboratory proves successful, and mass production was soon ordered all around the world for the creation of a similar toxin.
The gangsters, still desperate for a successful heist, tracked Mark Jackson and Inspector Komai and almost immediately jumped to the conclusion that Mark had hidden the real diamonds in a safe-deposit box. Hamako left to retrieve the stash, but instead fled solo with the stolen goods. The thieves left Jackson and Komai tied and doomed to death-by-dynamite, but the two men joined forces and only barely managed to escape.
Meanwhile, Dogora attacked once again, but this time, powerful artificial wasp venom quickly ate away at the creature. The robbers and the police clashed at the beach, and in the heat of a vicious gunfight, the gang was completely wiped out by a falling crystal boulder, once a section of Dogora's extraterrestrial flesh.
The wasp venom finally took full effect, and Dogora was no more. It was soon discovered that the diamonds Hamako had retrieved from the safe-deposit box were, in fact, synthetic. As this truth came to light, Dr. Munakata and his secretary left for the UN to discuss the peaceful potential of the Dogora incident with the world.
The film is unusual for Toho's giant monster series in that the creature is non-anthropomorphic and not portrayed by an actor in a costume. For scenes of it in its full form, the Dogora prop was placed in a small vat of water and puppeteered by people holding wires. This gave it the impression of it floating like an airborne jellyfish.
Originally, Dogora was titled (スペース・モンス Supēsu Monsu, lit. Space Mons) and was meant to be released in 1962.
Dogora's roar was reused for the Tsuburaya Production's TV show Ultraman, as the monster Bullton in ep 17, Passport to Infinity.
There were originally plans to feature Robert Dunham in a series of films based on the "Mark Jackson" character he played in this film. However, those plans never came to fruition.
As with its release of Attack of the Mushroom People, American International Television bought the rights to Toho's international dub in 1965 for television syndication. Since the film wouldn't play in US theaters, AIP-TV left Toho's English dub intact and added a new Dagora, the Space Monster title card. Allegedly, the name of the monster was changed to "Dagora" so that audiences wouldn't think the monster was a dog. Beyond the removal of the opening credits, the film was unedited. This version played for many years on late night TV and was released on home video by Video Yesteryear in 1983. The Media Blasters DVD uses the same dubbing featured in the AIP-TV version, but the edits are not retained.
