To whoever is attached as the screenwriter and director of Captain America,
Please do the right thing and set this film during World War 2 so that it can be done the correct way. Setting it during any other time would do the story injustice. The biography from the Marvel website states:
Steve Rogers was a scrawny fine arts student specializing in industrialization in the 1940's before America entered World War II. He attempted to enlist in the army only to be turned away due to his poor constitution. A U.S. officer offered Rogers an alternative way to serve his country by being a test subject in project, Operation: Rebirth, a top secret defense research project designed to create physically superior soldiers. Rogers accepted and after a rigorous physical and combat training and selection process was selected as the first test subject. He was given injections and oral ingestion of the formula dubbed the "Super Soldier Serum" developed by the scientist Dr. Abraham Erskine. Rogers was then exposed to a controlled burst of "Vita-Rays" that activated and stabilized the chemicals in his system. The process successfully altered his physiology from its frail state to the maximum of human efficiency, including greatly enhanced musculature and reflexes.This is what the movie needs to be about. Because of Cap being held in suspended animation for many years, the writer(s) and director can do the story the justice that it deserves.
After the assassination of Dr. Erskine. Roger was re-imagined as a superhero who served both as a counter-intelligence agent and a propaganda symbol to counter Nazi Germany's head of terrorist operations, the Red Skull. Rogers was given a costume modeled after the American flag, a bulletproof shield, a personal sidearm and the codename Captain America. He was also given a cover identity as a clumsy infantry private at Camp LeHigh in Virginia. Barely out of his teens himself, Rogers made friends with the teenage camp mascot, James Buchanan "Bucky" Barnes. Barnes accidentally learned of Rogers' dual identity and offered to keep the secret if he could become Captain America's sidekick. Rogers agreed, and trained Barnes. Roger met President Franklin D. Roosevelt, who presented him with a new shield made from a chance mixture of iron, Vibranium and an unknown catalyst. Throughout World War II, Captain America and Bucky fought the Nazi menace both on their own and as members of the superhero team the Invaders, which after the war evolved into the All-Winners Squad.
In the closing days of World War II in 1945, Captain America and Bucky tried to stop the villainous Baron Zemo from destroying an experimental drone plane. Zemo launched the plane with an armed explosive device on it, with Rogers and Barnes in hot pursuit. They reached the plane just before it took off, but when Bucky tried to defuse the bomb, it exploded in mid-air. The young man was believed killed, and Rogers was hurled into the freezing waters of either the North Atlantic. Neither his body or Bucky's were found, and both were presumed dead.
For everyone's sake, please do it the right way.
Furthermore, the best person when it comes to a World War 2 period piece would be none other than Steven Spielberg when it comes to a possible director. And we all know that he can direct action-adventure films!
