Dr. Pretorius: We shall drink to our partnership. Do you like gin? It is my only weakness.
Dr. Pretorius: To a new world of gods and monsters!
The Monster: We belong dead!
Mary Shelley: It's a perfect night for mystery and horror. The air itself is filled with monsters.
Trivia:
Director James Whale originally did not want to do a sequel to Frankenstein.
When filming the scene where the monster emerges from the burnt windmill, Boris Karloff slipped and fell into the water-filled well. Upon being helped out, he realized he had broken a leg in the fall. The metal struts used to stiffen his legs (for the famous "monster lurch") helped keep the bones in place until they could be properly set.
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).
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.
