Eddie Munster is a fictional character on the CBS sitcom The Munsters, originally played by Butch Patrick. The only child of Herman and Lily Munster, Eddie is a werewolf. The role was later played by Jason Marsden in The Munsters Today.
Eddie is a typical all-American boy apart from being a werewolf and, in some episodes, showing some signs of being part vampire. Most noticeable is the fact that he sleeps in a chest of drawers. He has a stuffed toy werewolf named Woof-Woof, which bears an uncanny resemblance to Lon Chaney, Jr.’s character, The Wolfman. He attends elementary school, and aside from his pointed ears, severe widow’s peak, and Fauntleroy suit, he is a normal kid.
Eddie is very proud of his father, to the point of bragging about Herman’s abilities and deeds to his friends… although these boasts are often outright fabrications. In fact, Eddie volunteering Herman for a heroic deed (which is clearly beyond Herman’s capabilities, but one Herman nonetheless undertakes for Eddie’s sake) is a central theme in many episodes.
In the unaired pilot episode, the part was played by Happy Derman, who played a more aggressively wolfish boy. Butch Patrick was reportedly cast out of over 500 boys in March 1964, and would appear in all episodes broadcast on CBS.
When asked how he was selected to portray the role of Eddie, Patrick recalled “I had a lot of experience. But maybe it was because my fangs were my own teeth. My eyeteeth were so bad, that even when I closed my mouth they stuck out. I was about a head smaller than the other kids, and they liked that because it played off Herman’s height.”
