The Robot vs. the Aztec Mummy (Spanish: La Momia Azteca contra el Robot Humano) is a 1957 Mexican science fiction horror film directed by Rafael Portillo, and starring Ramón Gay and Rosa Arenas. It is the third installment in a trilogy preceded by The Aztec Mummy and The Curse of the Aztec Mummy, and a large portion of the film is an extended recap of the events from the first two entries. The three films were all shot consecutively.[3] The film remained in obscurity until late 1989, when it was featured as the second nationally broadcast episode of movie-mocking television series Mystery Science Theater 3000.
