Right now the studio is remaining tight-lipped on exactly what the role will be, but with the casting call going out for a "tall, brunette, athletic and exotic" female, all the signs are pointing to Wonder Woman finally making her big screen debut in the current DC Comics universe. Apparently recent rumours that Thor's Jamie Alexander might also be in the running have been ruled out due to her ongoing Marvel commitments.
If these are the three contenders, my money is on Olga Kurylenko all the way. Sure, Gal Gadot made a hell of an impression in the F&F movies, but there's something waifish about her that just doesn't say "Amazon" to me, and frankly Yung has made little impression to-date. Kurylenko, meanwhile, has been confidently kicking arse on screen ever since taking the titular role in Israeli Nikita-esque thriller The Assassin Next Door back in 2009, proving she can more than hold her own as an action lead. She has the perfect balance of looks, athleticism and acting chops to really make something substantial of the role. Which brings me to my one concern...
While I am thrilled that Hollywood finally has the balls to put Wonder Woman on the screen (if that is in fact what is happening), I am less than enthused by the fact it will be Zack Snyder who is responsible for her debut. You only need to look at Sucker Punch to see how juvenile and lurid his take on the action heroine is - little more than an adolescent objectification that could wind up doing more harm than good to the character.
In the wake of films like The Hunger Games, there is an ever-growing audience in the target demographic willing to accept a gung-ho female protagonist in a tentpole action thriller, who needn't be tits & guns first, intellect and ability second (cough - Lara Croft - cough), and it's about time DC and Warner Bros put a little faith behind their property and did the same for one of their most iconic characters. The sooner they greenlight a standalone Wonder Woman film, with Kathryn Bigelow at the helm, the sooner any hope of a successful Justice League movie can become a reality, and female superheroes can finally get their due.
