hmmm, heres my idea:
ryu: marc dacascus (i agree, he would make a good ryu)
ken: i figure spike would make a good ken, but he'd have to buff up a bit...he looks quite scrawny
chun li: maybe lucy liu
sakura: the girl from crouching tiger hidden dragon, i forget her name
Guile - van damme (although he'd make an even better charlie, IMO)
Blanca: they should actually train an ape to do it
Bison: not dwayne johnson....totally wrong for the role.....not sure who though...possibly arnie
Cammy: heidi klum, i say
Balrog:since he did such a good job in Ali, will smith may be able to do it
aaaaaaaaaaaaaaaaaand...
Dan by Mike Myers....cmon....
