El Jorobado de la Morgue on AllMovie

One of the more notorious Spanish exercises in gory horror, this film from Basque director Javier Aguirre stars Jacinto Molina (aka "Paul Naschy") as a hunchbacked Swiss morgue attendant named Gotho. He's in love with a woman who dies of tuberculosis, causing Gotho to grab an axe and chop up some medical students who want to dissect her then hide her body in a dank crypt. A hallucination scene featuring the woman's body being eaten by rats while Gotho beats and burns them featured real rats, who bit Molina several times. Eventually, Gotho strikes a bargain with mad scientist Alberto Dalbes, who agrees to raise the hunchback's beloved from the dead in exchange for fresh corpses from the morgue to feed his monstrous blob-like creation. Rossana Yanni appears as an imprisoned psychiatrist, and the film co-stars Maria Perschy and Vic Winner
