I suspect Hemsworth may have been cast for his appeal to fangirls, rather like Robert Pattinson in "Twilight." He's a little too tall, blonde, blue-eyed and hunky to be super plausible. He can definitely become a star, but it may be in the Peter O'Toole tradition; I can more easily imagine him in a remake of "Lawrence of Arabia" than as a settled spouse in a domestic drama.
