I really think and hope that The First Avenger: Captain America film is set in the 1940s for half the movie and the other half set in 2011 where Captain America is revived by SHIELD and Nick Fury. I would prefer this idea because The Avengers film shouldn't be all about finding Captain America. If this is so, then the main villain, would have to be a villain of Captain America's. They could just have Captain America become frozen in 1940s then have a time elapse to 2011, where Red Skull has removed his mask and is with HYDRA and Baron Strucker, making the film have 2 villains instead of just the Red Skull. And to make a twist, Baron Strucker is a villain of Nick Fury also, and we know Nick Fury will be in almost every film, so that would be perfect. What do you think?
