Jessica Alba would have been a great choice for Wonder Woman. She's got everything you'd want to see in Wonder Woman. She's got the looks: tall, brown hair, exotic. And she's got the skills. She was practically a futuristic Wonder Woman in the show 'Dark Angel' produced by James Cameron. In that show she played a genetically modified warrior in a dystopian future. It lasted two seasons and it was actually pretty good!
She's also been in the superhero genre before in the Fantastic Four series of films. Although some people think her acting isn't so great, I think she makes up for it in charm. She was even cast as Wonder Woman in an early 2000s television show, but that ended up falling through. Something about Jessica Alba in an early 2000s Wonder Woman show just sounds perfect, doesn't it?
