The film centers on Mary Surratt (played by Robin Wright Penn), one of the accused members of a conspiracy to assassinate President Abraham Lincoln, and in the wake of the case, the first woman executed by the US government. James McAvoy plays Frederick Aiken, a Union soldier who reluctantly defends Mary Surratt.
Redford says of the film:
"There was a question of whether she was complicit, guilty by association, or even more guilty. The lawyer that defended her didn't want to defend her. He was a Union soldier who became a lawyer."
The Conspirator was released April 15th, 2011 and stars Robin Wright, James McAvoy, Evan Rachel Wood, Alexis Bledel, Justin Long, Tom Wilkinson, Norman Reedus, Kevin Kline. The film is directed by Robert Redford.
