The evil Dr. Markoff (J. Carrol Naish), is a scientist experimenting with a cure for the rare disfiguring disease acromegaly (which cult actor Rondo Hatton, "The Brute Man" suffered from in real life). At a concert by pianist Anthony Lawrence (Ralph Morgan) he sees a beautiful girl who reminds him of his late wife. Backstage he discovers that she is Lawrence's daughter Patricia (Wanda McKay). He sets out to woo her, but after she spurns his advances he deliberately infects her father with acromegaly with the plan of forcing him to "give" his daughter to him in return for a cure. I really enjoyed this nasty b-grade thriller. It was obviously made on a tiny budget, the script is pretty dumb and the acting is variable, but I got a kick out of how twisted the central premise was, and Naish was extremely entertaining as Markoff. McKay's cute, future Frankenstein's monster Glenn Strange is one of the supporting cast, AND there's a guy in a gorilla suit, always a sign of a silly but fun movie in my book. 'The Monster Maker' is recommended to fans of old school "bad" b-grade horror movies.
