Originally planned as a sequel to Satan's Sadists (1969), with Russ Tamblyn and other "bikers" reprising their parts from that film. However, not long after filming began, it was decided to turn it into a horror film instead of a biker picture and much of the footage with Tamblyn and other actors from the first film was cut out. They were unable to cut them completely out of the movie, though, which is why Tamblyn and his biker gang seem to be wandering in and out of the film, with no connection to the story line and with not much to do.

At this point in his career, J. Carrol Naish was very ill and frail and could no longer remember dialogue, so he read it off cue cards. However, he had only one real eye, so in his dialogue closeups you can see one eye moving back and forth, reading the lines, while the other eye remains fixed in position.

J. Carrol Naish had false teeth, and their clicking sound can be heard several times on the soundtrack.

Durea's use of the same chemical injection alternately cause Groton to transform, and prevent him from transforming.

The order of exhibits changes from scene to scene.

When Judith is tied to a railing, the ropes are so loose that she could've easily escaped.

Dracula: My coffin awaits you becoming immortal in its embrace!

Dracula: No, him! Him! Him! No! Him! Him!

Dracula: And all those who would meddle in the destinies of Frankenstein and Dracula... will see an infernal bloodbath the likes of which has not swept the Earth before!
