Now, while Jensen Ackles has been my top choice for Captain America for a long time, I've been thinking of other possible candidates for the part of the All-American super soldier.
His name is Teddy Sears. He's made his name on several TV shows, being a regular on Raising The Bar and One Life to Live, and cameos in many others, including Dollhouse. It also helps that he's a born and bred American, has the blonde-haired-blue-eyed look, is 6'3, and with the proper bit of bulk, would look every bit a super soldier.
