Rule of thumb in the 1960's in making a schlocky horror film: visit local pre-school's and kindergarten's, collect various art supplies (paper mache, styrofoam, large pieces of cardboard and colored construction paper, popsicle sticks, etc.), and hire a faded actor like John Carradine or Lon Chaney Jr.). Pull together bits and pieces of short stories and expand with as many idiotic small details that you can think of. Mix all of these together and stir. Bake for an hour, and then send to a drive-in theater, and there you have it: a schlocky horror film along the lines of "Face of the Screaming Werewolf".The faded star here is Chaney, running around, snarling, grabbing screaming women, then barely missing an elevator as a woman inside screams. Another ghoul throws a man off of the roof, but fortunately, there's an awning to catch him. The film starts off with a flashback to an Aztec temple sacrifice ceremony where one of the characters in the present day was once an Aztec princess. This sequence is where the paper mache and styrofoam come in handy, painted to look like bricks, and held together by jarred paste. The actors look nothing like what the Aztecs must have, and the sequence as a whole goes on far too long. Chaney is there for name only, and most of the intended frights only bring laughs. At only an hour, this won't make you feel that you've wasted too much time, and you'll find plenty to laugh at, not laugh with.

I just finished watching this film and I'm almost speechless about it. This movie is so weird that you would have to see it to believe it. It's in no way a good story - yet there is something about it that I enjoyed.The music soundtrack is actually very hypnotizing and helps make the film better by enhancing the scenes - and it's just as odd as this pieced together movie.As other reviewers have mentioned, this movie is bits and pieces of two films put together to make one film(La momia azteca and La casa del terror) with some added footage to complete it. The spliced together movies does not make any sense at all. I expected some sort of explanation at the end of the film to help tie together The Mummy and Werewolf - but there is no explanation to help summon it all.But there is something about this mixed up movie that is good, entertaining in a strange sort of way. I would rate this movie 4/10 BUT the oddness of the movie and the strange hypnotizing soundtrack gets bonus points so I will rate this movie 6.6/10

A group of scientists enter a pyramid that has been explored many times and find a monster and a mummy without the use of a single pick-ax or stick of dynamite. They just walk until they find them. True, they had a psychic with them, but she seemed to be as lost as the rest. The mummy and monster are brought back to civilization, where the monster escapes and the mummy turns into a werewolf! Yes, it's another cobbled together mess from Uncle Jerry Warren. This time he slaps together bits of two Mexican monster films and spends about four dollars on some American actors doing some framing scenes. Not as hilarious as Attack of the Mayan Mummy, but it keeps you glued to the screen trying to follow the story. (Spoilers-How can you spoil something already gone bad?) An overweight mummy (a first!) is placed in a dry cleaning machine. When he comes out, he's wearing modern shoes, pants, belt and dress shirt. Oh, yes, and he's a werewolf on top of being an overweight mummy. The other monster, woman in his arms, knocks out two well built men who come upon him, without putting down the woman. Three men steal the mummy the night when it's about to be shown to the public. They drive away, followed by the police. The police catch up with the car, then takes the next off ramp, letting the bad guys get away. I'm surprised that they didn't have poor Lon Chaney (the overweight mummy) sitting in the back seat! A real mess. My rating: 2 out of 10. BAD.

Can a movie, that actually consists scenes from two mexican monsterthrillers plus additional scenes from US for commersial interests, be successful? - Yes! This is a dreamlike and incoherently edited oddity that tells a story of a centralamerican mummy found at the excur- sions of a pyramid. Also there is a mad scientist who in his experiments with revivification, succeeds in waking the mummy. And there´s a thunderstorm! The mummy is transformed into a werewolf played by Lon Chaney jnr! Its wild, suspenseful, trancendental, poetic in its "silents" looks and pace and there is a musical number of exotica style too, with an Yma Sumaclike vocalist in a "flashback" Aztec ritual scene! I was overwhelmed of the total impact of this movie as seen through the eyes of someone who value uniqueness and improvised quality in lowbudgetfantasy that really works as avantgarde poetry. The images and atmosphere of Ancient Civilisation, Pyramids, detectiveworks, a scary rotten walking mummy, a terrifying werewolf,terrified womens faces and all these mysterios cuts between scenes from one film to another creates a nightmare with no other logic than the dream´s own. I recommend this for all who has a vivid imagination and for all of you who believe that insanity can be genial!
