I've been rewatching the first season of Penny Dreadful in preparation for this blog series, and wow, how did I not know Josh Hartnett's "Ethan Chandler" (actually Larry Talbot) was a werewolf from the word Go? Sometimes I'm slow on the uptake. In this case though, I know why I didn't figure it out right away: all the other characters in Penny Dreadful are pulled from classic Gothic literature. The Wolf-Man, however, entered the horror lexicon through cinema.

The closest thing we have to a werewolf book is Robert Louis Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde, and that character is represented elsewhere in the series. So Ethan might technically be the Wolf-Man, and yes his real name is the same as Lon Chaney, Jr.’s character in the Universal film, and good for you if you figured that out before I did. But I've only seen the original Wolf-Man one time, and Josh Hartnett's take on the character is remarkably different from the classic monster in many ways.
