A werewolf movie was turned into a "Frankenstein" movie because of a promise to deliver a Frankenstein double feature. The movie has absolutely nothing to do with Frankenstein or his family -- though there is a Wolfstein in the film.

Monster A-Go-Go had no monster.
-
The Creature With the Atom Brain had no creature. (But an awesome Roky Erickson song.)
-
The Thing That Couldn't Die was a warlock that had his head severed. A human being is not a "thing." Thing is a nondescript term for that which you have no description for.
-
Dracula vs Frankenstein (a retitled Operation Terror) did not have Dracula and the Frankenstein monster fight. In fact, it didn't have Dracula -- just some random vampire with exactly one scene.
-
Women of the Prehistoric Planet (origin of MST3K's "Hi-keeba!" had a couple of women as part of a crew that landed on a tropical planet with a snake and a lizard. That's as prehistoric as it got. The women themselves were not native to the planet.
Werewolves on Wheels had
two werewolves throughout the movie, only one of them road a motorcycle in wolf form. And he did so only in an attempt to run away. Oh, but wait, in the closing minute of the film, the rest of the bikers are turned into werewolves and we do indeed get about ten seconds of werewolves (plural) on wheels.
And Countess Dracula, a film about Elizabeth Bathory, only made sense in the closing minutes when,
imprisoned and condemned to die, the Blood Countess is called "Countess Dracula" in condemnation. This doesn't make any sense. The historic Dracula was not a vampire and the novel wasn't written until centuries after Elizabeth Bathory.
