The Oscar-winning filmmaker explained that it was important for Lincoln to present the politician's character flaws as well as his progressive beliefs.
"It was very important for all of us making this film to avoid being cynical, to avoid cynicism," Flicks and Bits quotes Spielberg as saying. "I think it was just as important for all of us making the film to avoid hero worship, because I think you can admire someone immensely, as I admire Lincoln, but without worshipping him."
Spielberg said that he also wanted to highlight many of Lincoln's hidden talents.
He explained: "I wanted to tell a story about Lincoln that would avoid the mistakes of both cynicism and hero worship and be true to the vastness of who he was and the intimacy of his life and the softer angles of his nature. I wanted to make a film that would show how multifaceted Lincoln was.
"He was a statesman, a military leader, but also a father, a husband and a man who was always, continuously looking deep inside himself. And he was a fantastic writer."
Joseph Gordon-Levitt made similar comments in recent weeks, by suggesting that Lincoln fairly portrays the president's strained family life.
Lincoln will be released on November 16 in the US and January 25 in the UK. Watch a trailer for the film below:
