Creature of the Walking Dead (1965) – Jerry Warren.

A demented pseudo-scientist Dr. Malthus (Fernando Cassanova) prolonged his life injecting an elixir of human blood is executed, and later resurrected by his no less ill-fated ancestor in this likeably lurid cut n' paste's Mexican/US creature feature! Once reawakened, Malthus Sr.'s deranged bloodlust returns undiminished by death, and his devilishly gruesome rampage draws the authorities ever closer to his monstrous laboratory. Creakier than a medieval codpiece, there's still much ripened psychotronic grisliness to be found in this cheap and fearful 60s creep-fest!

The delightfully grisly methodology of Dr. Malthus's fiendishly blood-sucking apparatus is still pretty grim to behold! Creature of the Walking Dead is generously stuffed with more cheesy corn than a bargain Burrito! This moodily monochromatic, shriek-slathered, blood-sodden B-Terror titbit unearthed from the musty vaults of gaudy Drive-in double thrills remains a horrific hoot! Creature of the Walking Dead explodes in a vile, shocking miasma of perversely purloined blood-plasma! No humane soul will remain untarnished after witnessing the diabolically degenerated lusts of that malign dessicated revenant, Dr. Malthus! 

 “The insurmountable quest of scientists has been to answer the unanswerable!!!!”
