Night of the Bloody Apes1969

Horror Vault's take

A desperate surgeon turns to radical and grotesque measures to save his dying son, transplanting the heart of an ape in a procedure that unleashes something monstrous on the streets. This late-1960s Mexican exploitation shocker blends surgical horror with creature-feature carnage in gleefully outrageous fashion. Raw, bloody, and unabashedly over-the-top, it earned its reputation as one of the wilder entries on the video nasty list.
