In all the commotion surrounding just who the frig would be playing The First Avenger: Captain America, we all neglected to needlessly stress out over who would play his plucky sidekick. Today comes word that Gossip Girl's Sebastian Stan will squeeze into Bucky's red tights and strike an arms akimbo pose. He is to Captain America what Robin is to Batman, what Ernie is to Bert, what Samwise is to Frodo, what Bernie Taupin is to Elton John.There have been a few different versions of Bucky in the comic and there is no word yet on how he will be portrayed in the film. You know, except for ridiculously. (THR)
