Harley Quinn (BTAS)

Trivia

 * Harley is Arleen Sorkin's best-known voice-over work. Although most people don't know it, her other work included regular behind-the-scenes work on Frasier (she is married to Christopher Lloyd, a writer and executive producer on the show). During rehearsals and studio tapings, Sorkin often provided the voice of guest callers on Frasier's radio show, before other actors' and actresses' voices were dubbed over in post-production.
 * During the episode "The Man Who Killed Batman", Harley performs "Amazing Grace" on a kazoo. Sorkin did the performance herself; the producers gave her a kazoo and asked her to give it a try while recording the episode. Later they said it was lucky they'd managed to do it in one take, because they were all helpless with laughter as soon as she'd finished.
 * Harley also appears in the non-DCAU series "The Batman," voiced by Hynden Walch, who voices Ace. Aside from certain exaggerated proportions, she looks quite similar to Harley's traditional appearance.
 * Arleen Sorkin returned to the role of Harley Quinn for the 2009 video-game, Batman: Arkham Asylum (not in continuity with the DCAU). In the game, Harley sports a different appearance to her traditional jester's outfit look, wearing what appears to be a modified nurses uniform.
