Here's more info. via Deadline:
BREAKING: Warner Bros and Zack Snyder have found their Wonder Woman. They’ve cast Israeli-born actress Gal Gadot in the iconic role and she will be part of Batman Vs. Superman, the film that will see Henry Cavill square off with Ben Affleck. Gadot has been in three Fast & Furious films, as well as Knight And Day and Date Night. Given that Warner Bros has bolstered its starpower with Affleck and has Cavill returning from the summer hit Man Of Steel, it makes sense to groom new stars in the supporting roles, the way that Marvel has done. All this is clearly gearing toward the long-awaited Justice League film, all based on the DC Comics characters.
Said Snyder: “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.”
