DreamWorks has announced that the film "will focus on the political collision of Lincoln and the powerful men of his cabinet on the road to abolition and the end of the Civil War."[8] According to Spielberg, Doris Kearns Goodwin's entire book about Lincoln's presidency is "much too big" for a film, and said that the film will focus on the last few months of Lincoln's life, the ending of slavery and the Union victory in the Civil War. Spielberg said that "what permanently ended slavery was the very close vote in the House of Representatives over the Thirteenth Amendment – that story I'm excited to tell." Spielberg plans to show "Lincoln at work, not just Lincoln standing around posing for the history books...arguably the greatest working President in American history doing some of the greatest work for the world."
