Another import horror chop-job courtesy of producer Jerry Warren, this time with a recognizable American star -- sort of. Lon Chaney, Jr. returns to Wolf Man mode once again (albeit a cheaper, low-rent version that seems to incorporate shag carpet swatches) in what was originally a Mexican monster spoof... but thanks to slapdash English dubbing and re-editing, the only laughs on display here are purely unintentional. The plot involves a mad scientist's efforts to revive a pair of mummified bodies recovered from the Yucatan Pyramid. The process works on the first mummy, which turns out to be the lycanthropic Chaney. While the monster escapes and goes on an uninteresting rampage in the nearby town, the second corpse is spirited away by thieves, who discover the hard way that their quarry is also capable of revival, even without scientific assistance. This messy film essentially consists of footage from the 1959 Mexican film La Casa del Terror, footage from 1957's La Momia Azteca, and new footage shot by Warren, all edited together.
