Captain America: The First Avenger First Avenger" tells the story of Steve Rogers, a sickly man from Brooklyn who is transformed into super-soldier Captain America and must stop the Red Skull, who intends to use an artifact called the "Tesseract" as an energy-source for world domination. "Captain America: The First Avenger" began as a concept in 1997 and was scheduled for distribution by Artisan Entertainment. However, a lawsuit, not settled until September 2003, disrupted the project. In 2005, Marvel Studios received a loan from Merrill Lynch, and planned to finance and release it through Paramount Pictures. Directors Jon Favreau and Louis Leterrier were interested in
Captain America: The Winter Soldier Robert Redford, and Samuel L. Jackson. In "Captain America: The Winter Soldier", Captain America, Black Widow, and Falcon join forces to uncover a conspiracy within S.H.I.E.L.D. while facing a mysterious assassin known as the Winter Soldier. A major influence in "The Winter Soldier" was conspiracy fiction from the 1970s such as "Three Days of the Condor", with the script also drawing from the Winter Soldier story arc written by Ed Brubaker. The script was written in 2011, with the Russo brothers entering negotiations to direct in June 2012 and casting beginning the following month. Principal photography commenced in April 2013
