aka The Aztec Mummy Against the Humanoid Robot
How bad is it? It's a lesser Mexican monster movie.
Should you see it? Not unless you're already a fan of Mexican monster movies.
This sequel to "The Aztec Mummy" has a lot of footage repeating the original. A mad scientist seeks treasure in a tomb that's guarded by a mummy, so he creates a robot with a living human brain to battle it. The robot is so bad that it has just a glass mask in front of a man's face and lightbulb ears. The slow moving bandaged mummy slowly defeats the slow moving robot.
