On October 11, 1997 the film was shown on the movie-mocking television showMystery Science Theater 3000. In his review of the film, Bruce Eder of AllMovie described the episode as a memorable one, specifically the cast watching the repetitive aerial dogfights between spaceships, and one of the hosts remarking that "Independence Day now seems like such a finely nuanced movie". The film was also released as Space Chief, Space Greyhound and Invasion from a Planet.
Reception
In later reviews of the film, Bruce Eder gave the film a one star rating out of five, stating that the film was "the kind of movie that gave Japanese science fiction films a bad name. The low-quality special effects, the non-existent acting, the bad dubbing, and the chaotic plotting and pacing were all of a piece with what critics had been saying, erroneously, about the Godzilla movies for years." The review stated that the films "cheesy special effects and ridiculous dialogue taking on a sort of so-bad-they're-good charm." and that the film was "thoroughly memorable specimen of bad cinema." In his book Japanese Science Fiction, Fantasy and Horror Films, Stuart Galbraith IV stated that the film "had a few surprises" despite a "woefully familiar script" Galbraith noted that the film was not as over-the-top as Prince of Space and that the opticals in the film were as strong as anything Toho had produced at the time. Galbraith had suggested the effects may have been lifted from Toei's The Final War from 1961.
