Trivia: Peyton List voices Batgirl. Peyton List also voices Poison Ivy. This is not the same person getting credited twice. It's two different people. Normally the SAG doesn't allow two living members to have the same name, but they accidentally missed the younger Peyton List (Batgirl). The SAG should have made the younger List use a middle initial or stage name. Incidentally, the younger List got her start in an uncredited role in an episode of "As the World Turns" which also featured the older List.
Trivia: Peyton List voices Poison Ivy. In the TV show "Gotham", List plays Ivy Peppers, who becomes Poison Ivy.
