I don't know if this could be possible, but what if we produce a second Captain America movie before the first Avengers? This are my reasons.
The first movie would be Steve's origin story, ending with him trapped by the ice and waking up in 2009/10.
But the second movie, in contrast to The Winter Soldier, would be about Steve comming in terms with...well, everything.
It's been over 60 years since the last time he was awake.
Based from the IRL movies (i know nothing about the comics) he wouldn't be aware about the Final Solution, considering his final fight with Red Skull was in February, with the first camps on the west being liberated by April.
Already he would have missed the biggest repercussions on the War, including the revelation of the Genocidal policies of Germany and Japan, the creation and deployment of Nuclear Weapons and the infamous war crimes by Allied Forces including the firebombings of Dresden, Tokyo and the sinking of the
Wilhelm Gustloff.
Steve joined the war believing that he was fighting a true noble cause against the Nazi bullies, and he most have certainly thought so after freazing.
What would he think and believe as soon he learns everything that he missed just in that year?
And that's not even mentionating the postwar-period and the Cold War (For this I will focus in the US)
The stalemate that was the Korean War that lasts to the present, the infamous distaster that was Vietnam, the Coup d'états and military dictatorships supported by the US since the 50s across Africa and Central/South America , and the current War on Terror in Irak and Afghanistan.
Steve fought in a war were "they were the good guys". But everything after that lost its black and white optic...
And all of this doesn't include the massive social transformations around the 60s, with spacial emphasis on the Civil Rights Movements.
Steve lived the status quo of the 1930/40s, which would be rejected by the next generations.
The world of 1945 is WAY different from the one of 2009/10.
In overall, I believe the second movie should be about Steve trying (and failing) in grasping his new reality. Coming in terms about how his "world" is good as gone (family, friends) adn that things aren't Black and White anymore.
A movie for focused on Steve Rogers as himself, not Captain America. Naturally he would have a foe to defeat, but it should be more about acceptance and self-discovery.
Thoughts?
To complement how much Steve missed (from minute 4:50)
