The Los Angeles Times debuted an image of a battle-hardened Captain America (Chris Evans) and Bucky in World War II. (Coming Soon also points out some scanned images of Stan as Bucky, as well as Hydra agents, that originally appeared at a French site.)
"Sebastian brought something really interesting and slightly on the dark side and really compelling to watch — when he's on camera, you're fascinated by watching him," director Joe Johnston told the Times.
He added, "You know, he was originally up for the lead, for the Steve Rogers role, but he didn't have quite the same earnest, I-want-to-fight-for-my-country aura that Chris has for this role. Sebastian has a little bit of the bad boy, he's a little bit of the James Dean type and that goes somewhat counter to the general perception of Steve Rogers. He wasn't quite right for Captain America, but I think he's perfect for Bucky because, really, he can have a little bit of that dark side."
