i'm not sure i can see him in the role, but i dunno... he might be good.
checking his
imdb profile i see that other than an uncredited role as an extra on stargate sg-1 (he was one of the jaffa in the second half of this season's pilot ep), x2 is the only thing he's done.
that's both good and bad. on the one hand, it means that there's no way for fans to tell if he has the acting ability for a starring role, and the directors will be limited to a brief screen test. otoh, unknowns are good for roles like this. you're not distracted thinking of everything else the guy's done. you just see clark kent/superman on the screen. of course, that same thing makes it harder on the actors afterwards because it defines their careers. after the movie, everyone looks and goes "hey, that's superman!" and it's hard to see him in a different role.
anyway, i found a pic of him on imdb, so i thought i'd share.
he does seem to have the physique. i just don't know if he can act.
