“The Werewolf of London” wasn’t the first werewolf movie ever made (that was the silent film, “The Werewolf,” in 1913) but it predated the more famous “The Wolf Man” by 6 years.
It is worth a view for its interesting story line, elegant leading lady, some very humorous scenes and its more spooky elements.
Both movies — “The Werewolf of London” and “The Wolf Man” — were produced by Universal Studios, but the latter became more well known.
You can rent it on YouTube. Here’s the preview that links to the full version.
