'La invasión de los Vampiros' (1963) aka Invasion of the Vampires Dir. Miguel Morayta Martínez.

This stylishly mounted, darkly atmospheric example of vintage Mexican Vampire Gothic includes striking scenes of crepuscular creepiness that readily matches Italian maestro, Mario Bava. The unearthly, teeth-grindingly dissonant score by maestro, Luis Hernández Bretón manifestly gives Martínez's melodramatic, strangely desolate, shadow-steeped B/W bloodsucking bacchanal a divinely unsettling quality! There's a terrifically macabre sequence wherein a malign multitude of freshly staked vampires grimly awaken in a smoke-hazed tomb and prowled the tempestuous night which oozed a fascinatingly bizarro, Carnival of Souls ambience! Performances are uniformly excellent, boasting impressive set design, the evocative cobwebbed Gothic milieu is impeccable, plus a bravura climax to rival the very best of Hammer Films. Miguel Morayta Martínez, I salute your truly magnificent Gothic masterpiece!
