Either Jessica Biel or Kate Beckensale would have made a descent wonder woman. Israeli twig woman with no acting ability? Not so much. As stated earlier, you need a Mediterranean woman who is both attractive and very physically built to pull off this role. Its starting to look like Afleck may be the strongest part of this project.....
And WW is not fucking female superman, but rather a more antihero reflection of him. She is powerful, like Supes, but more ruthless than Batman when dispensing justice, with the whole sovereign ruler and incarnation of Amazon mythology thing. For a really good take on the three characters and the dynamic between them, go find a copy of Kingdom Come.
