The Evil of Frankenstein (1964) on Netflix

Penniless, Baron Frankenstein, accompanied by his eager assistant Hans, arrives at his family castle near the town of Karlstaad, vowing to continue his experiments in the creation of life. Fortuitously finding the creature he was previously working on, he brings it back to a semblance of life but requires the services of a mesmerist, Zoltan, to successfully animate it. The greedy and vengeful Zoltan secretly sends the monster into town to steal gold and 'punish' the burgomaster and the chief of police, which acts lead to a violent confrontation between the baron and the townspeople.
