Chelovek-amfibiya

On the Argentine coast, the locals live in fear of the "sea devil", a fish-man who has been frequently spotted in the nearby ocean. In reality, he's Ichtyandor (Vladimir Korenev), a young man who was born human, but with a deadly lung disease. His brilliant scientist father Professor Salvator (Nikolai Simonov) grafted shark gills onto the boy, relieving his ailment and granting him the ability to breathe underwater. One day Ichtyandor rescues beautiful young woman Gutiere (Anastasiya Vetinskaya), and he falls instantly in love with her. Unfortunately, she's been promised in marriage to lout Pedro (Mikhail Kozakov). Also featuring Anatoliy Smiranin, and Vladlen Davydov.

I really enjoyed this colorful and energetic romance. It exists in its own, slightly surreal world, which is exaggerated by the setting and the characters all being Argentinian, yet played by Russians in the Russian language. The direction is propulsive and inventive, and there's a quaint joy to the 60's era aesthetic seen in the fish-man's silver suit and his father's high-tech lab home. I also appreciated the film's sense of humor. Recommended.
