This was another obscure Christmas-related title, a low-budget Mexican production from exploitation film-maker Cardona (NIGHT OF THE BLOODY APES [1969], TINTORERA! [1977]), which  like many a genre effort from this country  was acquired for release in the U.S. by K. Gordon Murray. Judging by those two efforts already mentioned, Cardona was no visionary  and, this one having already received its share of flak over here, is certainly no better! The film, in fact, is quite redolent of the weirdness which characterized Mexican horror outings from the era, but given an added dimension by virtue of the garish color (which, in view of the prominence of reds  apart from St. Nick himself, the Devil plays a major role in the proceedings  throughout, was essential). Anyway, in a nutshell, the plot involves Satan's efforts to stall Santa Claus' Christmas Eve rendezvous with the Earth's children; there is, however, plenty more wackiness along the way: to begin with, our portly, white-bearded and chronically merry man-in-red lives in a celestial palace who, apart from accompanying toy-maker kids from all over the world on his piano as they sing (laboriously for the whole first reel!) in their native tongue, visits Merlin  the famed magician at King Arthur's court, here bafflingly but amusingly prone to child-like hopping and mumbling gibberish!  once every year to acquire potions which would bring somnolence to the young and render himself invisible (by the way, the Wizard's anachronistic presence here is no less unlikely than his being a cohort of Dr. Frankenstein in SON OF Dracula [1974]!!); incidentally, by this time, he always seems to have gained some excess weightso Santa has to work out in order to be able to fit into each proverbial chimney! The Devil's antics (enthusiastically rubbing his hands together at every turn and generally hamming it up) to hold up St. Nick's delivery program, then, is perfectly puerile: indeed, their tit-for-tat shenanigans resemble an old Laurel & Hardy routine more than anything! To pad out the running-time, we focus on three sets of children: one, the lonely son of a rich couple who wants nothing more for Christmas than their company (projected as a wish-fulfillment fantasy where the boy finds his parents wrapped in extra-large packages!), a girl from a poor family who yearns to own a doll of her own (the horned one first tempts her to steal one, then invades the little one's dreams  to no avail) and a trio of brats who, egged on once again by Satan, think of nothing but causing mischief and eventually fall out amongst themselves. There is definitely imagination at work here, but it is applied with little rhyme or reason, while the overall juvenile approach keeps entertainment (unless one counts the film as a guilty pleasure) well at bay!
