Attack of the Mayan Mummy
By Cavett Binion
American "B"-movie mogul Jerry Warren can always be counted on to turn a cheap but fun horror import into a boring, unwatchable mess--as proven by this tedious effort, originally produced in Mexico as The Aztec Mummy and later padded out with deadly-dull exposition. The original film is silly enough; the first of a popular Mexican series, it involves the awakening of the mummy Popoca to avenge the desecration of his tomb by infidels. As a cost-saving measure, instead of re-dubbing the Spanish dialogue, Warren added new scenes with American actors, who drone on about reincarnation and past-life regression and bring the action to a screeching halt.

Comment: The last image pretty much sums up the linkage between Mesoamericans and horror. If blood and death were involved, the people had to have been evil, right?
The second link is the only semi-scientific reference I found to Maya mummies. And it comes from a UFO site. So far the existence of Maya mummies remains unconfirmed, to put it mildly.
