Chris Evans has officially accepted Marvel's offer to play the Sentinel of Liberty for 9 films. One of Marvel's flagship characters, Captain America is the leader of the Avengers (Chris Hemsworth as Thor, Robert Downey Jr. as Iron Man . . .and possibly Ed Norton returning as Bruce Banner/Hulk?) and has one of the more interesting stories. Steve Rogers began as a sickly young patriot with a desire to serve his country during World War II. Rogers was rejected from the army, but was accepted for Project: Rebirth, and became America's super soldier.
Captain America's nemesis is still in talks for casting, but the main candidate is currently Hugo Weaving.
The First Avenger: Captain America, is due out July 11, 2011 and will be followed by the Avengers, as well as various planned sequels.
