Watching this film is an enjoyable event. With a cast of hilarious and respected actors and actresses, this movie is one of the funniest and greatest Toho sci-fi movies I've seen. It starts off with an intriguing intro of how a scientist discovers disappearing satellites in space.
Then, it kicks off to these band of outrageous gangsters who wants sparkling diamonds for their loot. The suspense builds when some of the gangsters get lifted up into the air by an unknown phenomenon, later known as Dagora (or Dogara) the Space Monster, who has a thing for diamonds. Instead of buildings, vehicles, bridges, and structures crushing to the floor, they actually rise to the air as Dagora lifts away everything in its path. Dagora is seen in many shapes and sizes, including a giant jellyfish (with "animated" tentacles), shining "stars," and a floating piece of genetic-like substance. Screenplay writer Shinichi Sekizawa did an excellent job on the script.
The scientists trying to figure out a weapon in order to use to defend Japan from Dagora while the detectives try to nab the diamond lovers couldn't be more inspiring and intriguing in this movie. Composer Akira Ifukube gave a haunting and terrific music score and director Ishiro Honda directed one of his best. Some hilarious parts in the movie includes the part where the character Inspector Kommei tries to shoot a gun, only with confetti coming out; the part where Eiji the Safecracker eats a sugar crystal (which he later found out is a fake diamond) and then laughs like a hyena; the scenes of karate fights and the part where the Gangster Moll asks the train conductor to show her where to make a call when the phone is actually a few inches away from her! The only jewelry oriented monster sci-fi flick I've seen, this film is to be watched by all sci-fi fans. There are some plot-holes here and there, like why did the gangsters have to wait so long to steal the diamonds from Jackson, and why did the Gangster Moll have to call her crew to come meet her, since she wants the diamonds all to herself anyways? Could have used more action and suspense from the gangsters, but overall, a fun film. You'll never wear a diamond necklace or diamond ring the same way again.
Grade A-
