sorry to say, but i think unless SR's sequel does well, Routh's future in hollywood will be low-key at best (similar to Reeve). i can't see him landing any major acting roles for big movies.
i'm not convinced the guy can act -- and there's too little in SR to sufficiently judge him. now he might wow some auditions and land roles, but based on SR, i don't see him in any leading roles.
this guy isn't from jilliard like Reeve, and it seemed to show with what little i saw of him onscreen. i see him having a career at best like Chris Reeve's -- at worst, like George Reeves.
