- The Other Darrin: In addition to looking younger and more attractive, Janet Van Dorn was also given a new voice actress. She was voiced by Lynette Mettey in Shadow of the Bat. Here, she's voiced by Stephanie Zimbalist, daughter of Efrem Zimbalist Jr., who voices Alfred.
- Real Life Writes the Plot: The Scarecrow has no dialogue because Henry Polic II was recovering from throat surgery and thus unable to record lines.
- What Could Have Been: According to an old interview, the basic plot of this episode was originally pitched as the series' first movie, hence the much-larger-than-usual villain roster.
