That female role is Wonder Woman after all, like BC was the very first to report, and Fast and Furious actress Gal Gadot will be playing her in Batman vs Superman.
Zack Snyder released this statement on the casting:
Wonder Woman is arguably one of the most powerful female characters of all time and a fan favorite in the DC Universe. Not only is Gal an amazing actress, but she also has that magical quality that makes her perfect for the role. We look forward to audiences discovering Gal in the first feature film incarnation of this beloved character.
