Batman: Arkham City, which the actress had done since the character was conceived in Batman: The Animated Series. She will be replaced by veteran actress Tara Strong, who voiced The Huntress in Batman: Brave And The Bold.
Her hiring wasin a Q&A on the Batman community forums.
When asked how different Harley was from The Huntress, Strong obliquely paid homage to Sorkin, "Stepping into the role of Harley Quinn is an enormous honor that I do not take lightly. She has an established voice and character that I definitely wanted to honor. Huntress is a completely different character that I helped create vocally from scratch."
Strong also commented on the character's role with The Joker. "Harley Quinn is classically protective of The Joker, fiercely so. She has a unique mix of psychopath and vulnerable girl sweetness. She is crafty and sharp. I see her as a force to be reckoned with," she said.
Batman: Arkham City is due to be released on PC, Xbox 360 and PlayStation 3 on October 18, 2011.
