Mad Monster Party?

In order to keep expenses down, the film's producers did not want to pay royalty fees for the use of the names "King Kong", "the Frankenstein Monster", "the Bride of Frankenstein", "Quasimodo" and "the Creature from the Black Lagoon". That is why many of the characters - though recognizable - are all called by different names; i.e., King Kong is "It", the Frankenstein Monster is "Fang", the Bride of Frankenstein is simply "the Monster's Mate", Quasimodo is called "the Hunchback of Notre Dame" and the Creature from the Black Lagoon is called simply "the Creature". The names "Count Dracula", "Dr. Jekyll and Mr. Hyde", and "the Invisible Man" were in the public domain at the time of the film's production and thus, as no royalty fees were required for their use, they appeared in the film.

When the clock chimes, Baron Boris von Frankenstein says it is 1:00, but the clock actually reads 6:55. In addition, it chimes six times.

In the new DVD release of the film by Anchor Bay, at the very end of it the word "Yeah", which is sung by Francesca and followed by a couple of creepy musical notes, is not included.
