Harley Quinn Already Getting A Spinoff Movie, With An Important Twist. Harley Quinn has been a staple in DC Comics staple since she was introduced in Batman: The Animated Series, and this August, sheâs finally making her theatrical debut in Suicide Squad, played by Margot Robbie.
Harley Quinn has been a key member of multiple iterations of the Suicide Squad teams in the comic books, so introducing her on screen would seem like a no brainer.
