Well, a sidekick in the quest to side kick the shit out of some Nazi’s. Sebastian Stan will play Bucky Barnes. In the comics, BB was a teenage orphan who was a big fan of the army, but was too young to sign up. Through a work experience program with Captain America (or something) he discovered who CA was and signed up for some Nazi scalping experience! And apparently Stan has signed up for more than one CA movie!
