Christopher Markus and Stephen McFeely in negotiations for "First Avenger: Captain America."

Christopher Markus and Stephen McFeely are in negotiations to pen Marvel Studios' "First Avenger: Captain America." The dealmaking occurs about a week after Joe Johnston boarded the project as director.

Marvel's Kevin Feige is producing.

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.

In modern times, the character starred in his own long-running comic series and also was a charter member of Marvel's superteam, the Avengers.

Kicking off with "Iron Man," Marvel Studios' slate of movies -- including "Thor" and the "Iron Man" sequel -- is building toward an "Avengers" movie set for release in 2011, in which the characters from the films team for one big adventure. "Captain America" is scheduled for release May 6, 2011.

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

Markus and McFeely, repped by UTA, worked on "The Chronicles of Narnia: The Lion, the Witch and the Wardrobe" and its sequel, "Prince Caspian." The duo also wrote HBO's "The Life and Death of Peter Sellers."
