Bring inAnne Hathawayas Harley Quinn would be a great balance. Although she has already played Catwoman in Christopher Nolan’sThe Dark Knight Rises, she could definitely make the switch to Harley. After her appearance inThe Witchesas the creepy Grand High Witch, her versatility should clearly not be questioned.

With Harley Quin being portrayed byChristina Ricci, this pairing would be more than interesting. Ricci has a long career playing strange women roles. From her childhood appearance as Wednesday Addams to her 1920s flapper character Zelda inZ: The Beginning of Everything, her range knows no bounds.
