Trivia: In the original ending, Henry Frankenstein dies or is killed before the monster throws him off the windmill.
Trivia: To accommodate all sorts of viewers, the studio also made a silent version of the film (for cinemas without sound equipment) and a Spanish-speaking version (to be shown in Latin America). The Spanish version is considered a better film, because it was filmed after the English takes each day, so the Spanish director and actors would watch the English takes and decide how to improve on them.
Trivia: This was the first horror film to win an Academy Award.
