Trivia / Justice League Unlimited S 1 E 5 This Little Piggy

• The Cast Showoff:
  • Kevin Conroy gets to show off his singing skill as Batman, something the creators had been trying to incorporate into the show for a while after discovering his talent.
  • Circe is voiced by Broadway actress Rachel York, so she naturally gets a chance to demonstrate her musical skill as well.
• What Could Have Been: According to DVD commentary, the Joker was supposed to make a cameo in the episode. He, Harley, and their crew would have been plotting something when Batman walks by cradling Wonder Pig in his arms and talking to her. The whole thing causes Joker to throw his arms up in defeat and walk away.
