Mischa Barton seems to be exactly what film studios are looking for in a superhero - Warner Bros are rumoured to be considering her to play either Supergirl or Wonder Woman in their forthcoming films about the ladies in tights.
Moviehole.net claims that Mischa is up for the role of Superman’s cousin in a movie that will be released on the back of Clark Kent’s return to the big screen this summer. Whether this will be a remake of the 1984 Supergirl film or a new story featuring the heroine hasn’t been confirmed.
Supergirl OR Wonder Woman? Those are two rather...different ends of the casting spectrum, wouldn't you say?
Although, I would say Mischa is just about twiggy enough to play Supergirl as drawn by Ian Churchill. ;)
