A disfigured former professional wrestler, El Murciélago (the Bat), driven mad by his condition, lives a life in hiding, scheming for opportunities to best other wrestlers — he has henchmen kidnap them and bring them to his secret lair for that purpose — and obsessed with a beautiful singer. Fortunately for the world, the masked wrestler Blue Demon is ready to battle the Bat and all his scientific achievements and criminal power. The influence of The Phantom of the Opera is clear, but the story is engaging and the action sufficient.
Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
Movie 271 for 2021.
