Planet Prince was a 1958 Japanese tokusatsu made by Toei Films that was made in the wake of the success of Super Giant (Starman in the U.S.) that went from a 49 episode TV series to two theatrical movies — Planet Prince and Planet Prince: The Terrifying Spaceship — released one week apart.
Prince of Space is both of those movies smashed together, edited and dubbed into English. His enemy, the Ambassador Phantom of the Silver Planet, has been renamed Dictator Phantom of the Planet Krankor. To make things even goofier, the American translation of our hero’s real name — Waku-san — is Wally. Hey everyone! Here’s Wally to save the world!
The Dictator Phantom is really pretty great. He looks like a chicken masked Darth Vader and is given to saying things like, “Come on out or we’re gonna kill some children!” and “I will arrive tomorrow night at precisely eight o’clock. At that time I shall make my wishes known to you. You will obey them…or die! Have a pleasant night’s sleep!”
The man who wrote all this, Masaru Igami, was also behind Johnny Sokko and His Flying Robot, Kamen Rider and Legend of Dinosaurs and Monster Birds.
