When Harley Quinn first appeared on Batman: The Animated Series, she came complete with an over-the-top cartoony voice that was just this side of maddening. This was no coincidence. The voice, provided by actress Arleen Sorkin, was a pretty important part of Harley since Harley herself was inspired by Arleen Sorkin, and specifically this scene from the soap opera Days Of Our Lives.
Isn’t that ridiculous? It is. From that one appearance as a really off-putting clown, Paul Dini created another really off-putting clown to assist a third off-putting clown in his campaign of mayhem in Gotham City, and thus Harley Quinn came to be.
