Previously, Marvel Studios has conducted testing on three actress: Kiera Knightley, Alice Eve and Emily Blunt for the role. Then, Marvel decided to make an offer to Blunt but she has now officially passed. Well, Blunt was once offered the role of Black Widow in Iron Man 2 but she was forced to pull out too due to conflicting schedules with Fox's Gulliver's Travels.
On another development, Marvel Studios has announced the casting of Sebastian Stan to play Captain America's sidekick, Bucky Barnes, according to The Hollywood Reporter. In comic book lore, Barnes, a teenaged orphan, was too young to join the army but became one camp’s mascot. When he discovered Captain America’s identity, he joined Captain America as a partner in his Nazi-fighting escapades. The character died in Captain America’s final World War II adventure.
