This is one of the earlier sci-fi movies from Toho studios. Respectable Toho actors and actresses are in this movie including Kenji Sahara, Yumi Shirakawa, Momoko Kochi, Akihiko Hirata, and Takashi Shimura-all actors that appeared in the original Godzilla and Rodan movies. This story involves a group of cool looking aliens called the Mysterians, who want to possess a huge chuck of land in Japan and marry Earth women. The suspense builds when the Earth people resists the Mysterians' demands, which results in a battle for Earth action. Just to note, the actor playing the Leader of the Mysterians was Yoshio Tsuchiya. He also played the Vapor Man in 'The Human Vapor,' Controller of Planet X in 'Godzilla vs. Monster Zero,' and Businessman Shindo in 'Godzilla vs. King Ghidorah.'
Eiji Tsuburaya's advanced special effects highlighted a spectacular battle of fire, lasers, rockets, tanks and flying saucers between the humans and space aliens. A slow and mysterious, but sometimes militaristic and moving music score by Akira Ifukube. A dramatic and somber story by Takeshi Kimura. Directing was once again done by the great Ishiro Honda.
The downside, though, was that the story lacked a solid plot and the female leads weren't emphasized enough. There were too many scenes that depicted meetings held by the officials, discussing what to do about the aliens. These meetings were important in a way, but kind of boring. And, the robot monster, Moguera, was a terrific-looking monster, but wasn't utilized enough. But overall, a pretty cool feature for a sci-fi film made in the 1950s.
