As a DC Comics fan and after watching The Avengers last year, I really wanted to see a Justice League (JL) movie in 2015 as initially planned. I was disappointed when it was announced only a Batman/Superman film instead for that year. But, I am getting excited again when I read rumours about the addition of Wonder Woman (WW) in a cameo.
I know that WW had a recent failed attempt as a TV show due too campy but I think that Director Zack Snyder can portray her closer to the new 52 characterisation where she is as an emissary and ambassador from Themyscira with the mission of bringing peace to the outside world and with not secret identity. WW operating methods are made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. She is also with super powers at the same level as Superman.
The rumours included actresses like Olga Kurylenko (Quantum of Solace), Elodie Yung (GI Joe) , Gal Gadot (Fast & Furious) and Jaimie Alexander (Thor I and II) for this WW cameo which will introduce her for a JL movie and possible a solo film
Jaimie Alexander is my favourite from that group because she has played a relatively similar tough character (Sif in Thor and Thor 2) convincingly, tall (5' 9" - 1.75m) as any of the other contenders, also has the Wonder Woman look and with an age of 29, she can still wait a few years and still be young for a WW solo movie
I certainly hope that the rumour is true and Jaimie Alexander plays the role!
