Mary Shelley reveals the main characters of her novel survived: Baron Henry Frankenstein, goaded by an even madder scientist, builds his monster a mate.
Cast: (First 20, for the rest click 'Show All Cast & Crew' below.)
Mary Shelley: It's a perfect night for mystery and horror. The air itself is filled with monsters.
Dr. Pretorius: To a new world of gods and monsters!
Dr. Pretorius: We shall drink to our partnership. Do you like gin? It is my only weakness.
The Monster: We belong dead!
The Monster: Alone: bad. Friend: good!
Trivia:
The "body count" in the original cut was 21. This was trimmed to 10 after pressure from the censors.
Editing after previews resulted in the loss of a subplot in which Karl imitates the Monster's murderous modus operandi to eliminate his miserly aunt and uncle and direct the blame away from himself.
In the opening and closing credits the cast list says "The Monster's Mate" followed by a question mark.
Not long before filming began, Colin Clive broke a leg in a horse riding accident. Consequently, most of Dr. Frankenstein's scenes were shot with him sitting.
When the castle is self-destructing, the Doctor can be seen against the far wall. Yet he is next seen outside in the arms of his beloved, watching the explosions. There were two endings originally: the first had Doctor Frankenstein dying within the castle and this was filmed. But the producers judged this a bit harsh and wanted a happy ending, so they shot the extra footage (too expensive to re-film the explosions).
