is a Japanese tokusatsu science fiction film released in January 1956 by Daiei, and was the first Japanese science fiction film to be produced in color. In the film's plot, starfish-like aliens disguised as humans travel to Earth to warn of the imminent collision of a rogue planet and Earth. As the planet rapidly accelerates toward Earth, a nuclear device is created at the last minute and destroys the approaching world. The film, directed by Koji Shima, was one of many early Japanese monster films quickly produced after the success of Toho's Godzilla in 1954. After release, the film was met with negative reviews, with critics calling it "bizarre" and accusing it of using science fiction clichés. Warning from Space influenced many other Japanese science fiction films, such as Gorath. The film, along with other 1950s tokusatsu science fiction films, influenced director Stanley Kubrick, who would later direct 2001: A Space Odyssey. Plot A small ship travels to a rotating space station. Aboard the station, a group of starfish-like beings called Pairan discuss how to warn humans of an impending disaster, deciding on contacting Japanese scientist Dr. Kumara. Meanwhile, flying saucers are spotted over the skies of Tokyo, baffling scientists. A journalist tries to get a statement from Dr. Kumara about the sightings, but Kumara replies that there is not enough evidence to formulate a hypothesis. At an observatory, Professor Isobe spots an object in his telescope apparently releasing smaller objects. Isobe discusses his findings with Kumara and a physician, Dr. Matsuda, who believes they should get photographs via a rocket. The photographs they retrieve, however, turn out to be unclear, though they deduce the object has a high energy output. In the meantime, the extraterrestrials have been unsuccessfully attempting to contact humans. They begin appearing in lakes and rivers, frightening local fishermen and sailors. One of the aliens manages to secure a photo of Hikari Aozora, a famous Japanese entertainer. Their plan is for one of the aliens to mutate into the form of Aozora. Back aboard the space station, one of the Pairan leaders, Ginko, volunteers herself. Her starfish form is slowly mutated into a human form. On Earth, Toru, Isobe's son, discovers the disguised alien floating in the water. After her rescue, she exhibits superhuman characteristics such as jumping ten feet and materializing in different places without walking. Soon, she disrupts Dr. Matsuda's work on a nuclear
