Dr. Pretorius: We shall drink to our partnership. Do you like gin? It is my only weakness.

Trivia:
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.
The musical soundtrack for this film proved so popular, it was used again in the Flash Gordon serials starring Buster Crabbe.
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.
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.
In the opening and closing credits the cast list says "The Monster's Mate" followed by a question mark.
