The Mad Monster

The blood of a wolf he placed in the veins of a man... and created a monster such as the world has never known!

Dr. Cameron (George Zucco) has succeeded in his expierments with a serum which will turn a man into a wolf-like monster and is ready to avenge himself on the men who caused his professional failure. He uses it on his gardener Petro (Glenn Strange) and one after the other is killed by his creation. His daughter, Lenora (Anne Nagel), grows suspicious and confides with newspaper reporter Tom Gregory (Johnny Downs).

The Monster Maker

Mad scientist injects his enemies with acromegaly virus, causing them to become hideously deformed.

This is a mad scientist with an ugly agenda! Dr. Markoff (J. Carrol Naish) has concocted a formula that spreads a hideous disease named acromegaly - which extends bones and distorts facial features. Markoff has no moral dilemma in experimenting on unsuspecting human subjects. His amoral behavior assumes monstrous dimensions when famed concert pianist Lawrence (Ralph Morgan) is injected with the doc's disease-inducing serum. In return for an antidote, Markoff intends to exact more than his pound of flesh by extorting a fortune from Lawrence and demanding the hand of the musician's pretty daughter Patricia (Wanda McKay).
