Although this was the first episode produced, the first aired episode of the series was "The Cat and the Claw Part I", which premiered just the day before, This is likely due to the success of the movie Batman Returns.
Bruce Timm stated that he wanted this series to focus on "mystery, mood, drama as well as super hero action sequences" and that Man-Bat fit into those categories perfectly. In an interview, he said, "Man-Bat was chosen specifically [for the first episode] because he wasn't familiar to very many people outside of comic book fans. Nobody had any preconceived notions about him. It wasn't like the Joker, where you had to deal with people expecting him to be Jack Nicholson or Cesar Romero."
