Starring: Eva Green, Timothy Dalton, Reeve Carney, Rory Kinnear
And They Were Enemies - S2-E10
Continuity mistake: The moment Madame Kali drops down dead, killed by werewolf Chandler, she's still wrinkled and old. Later on in that scene, though, when the monster runs off, her skin is all nice and smooth again. (00:19:10 - 00:20:05)
Factual error: Educated characters, including an eminent scholar, continually translate 'Lupus Dei' as 'Hound of God'. Even someone with the most basic Latin would know it actually means 'Wolf of God'.
Trivia: A "Penny Dreadful" was one of several terms used to describe cheap horror comic books that were popular among the lower economic classes of Victorian England.
