Since I've rarely ventured into this thread forgive me if it has been brought up but is Sharon Carter in this movie do we know and if so has she been cast? I'd imagine that she would possibly appear at the end of the movie or maybe in the sequel.
It's a WWII story so its likely she will be saved for a sequel. I hope Cap doesn't get completely absorbed into the Avengers as I've never been an Avengers fan and his character has more than enough legs to carry a couple of movies solo with a supporting cast like in Iron Man. Since Cap tends to be a 'low powered' comic it might even have lower production costs once it comes into the modern era. Fingers crossed that we see Cap, Falcon, Sharon (maybe even sidekicks like Nomad, Demolotion Man, and Diamondback) in future Cap movies.
