With this episode, Kevin Conroy (Bruce Wayne / Batman) became the only actor to appear in all eight series in the DC Animated Universe. He previously appeared in Batman: The Animated Series (1992), Superman: The Animated Series (1996), The New Batman Adventures (1997) and Batman Beyond (1999) and later appeared in Static Shock (2000), Justice League (2001) and Justice League Unlimited (2004).
This is the only episode of the series to not have Robert Goodman's creator credit in the opening titles. Instead, it appears in the closing titles, along side the credit for Bob Kane, creator of Batman.
