It looks like Captain America is getting ready to set sail. THR is reporting that Christopher Markus and Stephen McFeely are currently negotiating a deal to be able to write Marvel Studios’ First Avenger: Captain America. The two have worked together before on The Chronicles of Narnia: The Lion, the Witch and the Wardrobe and its sequel, Prince Caspian. As well as HBO’s “The Life and Death of Peter Sellers.” Looks like they have a pretty good track record and good content to help push them forward.

The duo will be joining director Joe Johnston who signed on to the project last week.

It is being reported that:

Marvel’s “Captain America” will be a World War II-set movie, and the character will appear in the modern day-set “Avengers.”

Created in 1941 by Jack Kirby and Joe Simon for Timely Comics, Captain America is the heroic alter ego of Steve Rogers, who is rejected by the Army for being too sickly and undergoes an experiment that takes him to the pinnacle of human form. Paired with an indestructible shield, he becomes a symbol of the war effort, fighting Nazis and villainous scientists like the Red Skull.

They’re looking for a May 2011 release at the moment, but there is much to come before that happens.
