I thought that El Castillo de los Monstruos would be the perfect antidote to The Haunted House, which, despite its title, proved to be more of a “gorilla on the loose” caper than a spook show. El Castillo, by contrast, promises us a whole fleet of supernatural beasties, including a Dracula, a werewolf, a Frankenstein, a mummy, a hunchback, and a gill-man. Of course, these classic monsters were no strangers to Mexico’s B cinema back in the day, but this represents one of the rare occasions in which none of them were fighting a masked wrestler.
Conquistador de la Luna. I knew when I saw Conqistador de la Luna that I was destined to see El Castillo de los Monstruos. That’s not because Conquistador de la Luna was all that great, mind you, but because El Castillo came on the same “Dos Peliculas” double feature disc with Conquistador, and I was determined to get my money’s worth.
Santo and Blue Demon vs. The Monsters, a hallowed touchstone of masked wrestlers vs. monsters absurdity. As El Castillo shows, the company indeed took their monsters very seriously, even when presenting them in a comedic context.
Ladron de Cadaveres.
And then, of course, there is the sheer fulsomeness of the movie’s assortment of monsters. Only the most dedicated crank could find fault with this lineup. I mean, there’s even a toothy Neanderthal type who you could categorize as the film’s version of Mr. Hyde. And the realization of these creatures, by Mexican cinema standards, is really not that bad; You need only look at something like El charro de las Calaveras or the aforementioned Santo and Blue Demon vs. The Monsters to see how dire things could have been. (Though, I must say that this movie’s wolfman, who’s basically just a naturally hairy guy with fake fangs, looks an awful lot like VincenteLara, who played the part in similar fashion in Santo and Blue Demon vs. The Monsters, though I didn't see his name in the credits.) El Castillo even goes so far as to cast German Robles -- who became famous for playing vampires in more straightforward horror films like those in the Nostradamus series -- as its featured hemophile.
