Russ Tamblyn also stars in this classic bad movie from the director of "Brain of Blood." Zandor Vorkov plays Count Dracula, who convinces a wheel-chair bound descendent of the mad doctor to revive the Frankenstein monster. The puffy-faced make-up on this creation is actually somewhat cool.
Chaney shows up in footage from an unused gore film called "The Blood Seekers," playing a mad zombie. I saw this as a child on an afternoon TV movie show called "Dialing for Dollars," and even then was blown away by how bad this movie was. It's an absolute must-see and was recently re-released to video.
