The Wicked Witch of the West
The biggest no-brainer on this entire list. Wicked: The Life and Times of the Wicked Witch of the West is a hit book immortalized on stage by the long-running musical Wicked. So, why not give one of the foremost female antagonists the big screen treatment, already? Rumor has it that Universal Studios is moving forward on a film production, prompted by the screen success of Les Miserables, and even Disney animators have taken it upon themselvesto show how it might turn out. With the hit status of Frozen, with which it shares a musical pedigree, a focus on two female protagonists, and a similar theme of empowerment, we'd be surprised if this one didn't hit the big screen in the near future.
