There are reports swirling around the web that Mischa Barton - who currently spends most of her time pairing petulant alcoholic bisexuality with Marc Jacobs seperates as Marissa Cooper on The O.C. - is at the top of the list of potential stars for Joss Whedon's Wonder Woman. This sounds great - except for the fact that it doesn't at all. As Moviehole astutely points out, Barton's O.C. costar Rachel Bilson very convincingly wore the Wonder Woman costume last season to seduce Seth Cohen - and, she's a much sexier, much more interesting actress than the milquetoast Barton, who for all her dishwater-glamour doesn't strike me as super-heroine material. Also on the list: 7th Heaven alumna Jessica Biel. Not much of a choice. Whedon has apparently discounted reports that he may employ Sarah Michelle Gellar, Eliza Dushku, or any other actress once used on Buffy or Angel. Who would you cast in the role? I think Dushku - Buffy's Faith - would be awesome.
