I like Rose but i have doubts about her pulling this movie off. Bridgett was tough and a total kick ass babe. Rose doesn't have experience in tough female action roles. They should've picked Milla joviach. She kicks ass plus she looks good with red hair.
I can't see Ryan playing captain America. I think he is too much of a pretty boy. plus he doesn't really do well in serious roles. If they did pick him Captain America would come off cheesy and awkward.
