Chace's New Rival for Captain America Role: Sebastian Stan

Is there anyone in Hollywood who isn't in the running to play Captain America? Chace Crawford (Nate) has been on the shortlist for weeks, along with half a dozen others, and today a new actor joins the pack — a familiar face for Chace: Sebastian Stan (Carter Baizen), also known as Leighton Meester's boyfriend. Good thing the show already wrapped for the season — things could have gotten awkward on set. Of course, Nate and Carter are supposed to hate each other, so maybe it would just add a little more zing to their scenes.
