Revlver- You clearly don't read comic books if you think Wonder Woman's attractiveness should not be in account when casting the character, why are you on a comic book forum?
Wonder Woman is supposed to be insanely attractive, multiple members of the JL have had crushes on or flings with Wonder Woman. Shes supposed to be drop dead model gorgeous. Cornish is not that. Mila Kunis is.
Mila Kunis is infinitely more attractive than Cornish but thats not why she is a better choice. It helps though. Cornish has no appeal, shes not cute, shes a mediocre- to ok actress, and hasnt been in anything worth noting. While Mila Kunis is one of the most hottest celebrities right now star power wise and appearance wise. Shes also a better actress than Cornish and gets much higher profile roles. See Black Swan.
And its funny that you would make fun of a casting idea of mine while you have James ****ing Franco as Batman in your signature. Thats kind of embarassing if you pride yourself in your superhero fancasting ability. You should hook me up with some crack... maybe then that idea would make sense to me too. James Franco is a fantastic actor but him as Batman is seriously insane, and I honestly believe if you want that to happen, that you dont have respect for the fantastic character that is Batman. That is pissing on the idea of Batman.
Have you no taste man?
OH! and here's a picture of your
woooooooooonderful and truly
inspired casting choice for The Flash

Wtf dude do you just not respect these characters enough to want good or appropriate actors for these characters?
The casting of Wonder Woman and Flash needs to be handled VERY carefully.... basically I'm really glad you have no power at WB
