'Lincoln's' Oscar Nominees Talk To Oprah About Making The Film (VIDEO)

It's the historical drama that is leading the Oscar race with 12 nominations, including best picture, best director, best actor and best supporting actress. So what made the movie "Lincoln" Oscar-worthy? In this clip from a recent episode of "Oprah's Next Chapter," Steven Spielberg, Daniel Day-Lewis and Sally Field talk with Oprah about their experiences making the film.

Spielberg, on making the movie so intimate: "I don't know how else to make a movie except to try to find some aspect of the experience that I haven't done before. If I've done it before, I'm fearless. I need to wake up in the morning and get to the set and feel that I have an upset stomach. If I feel a little bit unsettled than I'm more able to rescue myself by taking risks and doing things that I didn't know that I was going to do that morning."

Day-Lewis, on having a year to prepare for the role of Lincoln: "...I have a fairly demanding family life. Quite apart from that, I knew that I would need that time. And it's been one of the great privileges of my life, and I don't expect to have a greater one, exploring the life of this man who I grew to love very, very dearly."

Field, on her role as Mary Todd: "As an actor I kind of always felt that Mary Todd would be somebody for me. I always felt it. So to me, the environment that Steven and Daniel had set up was without a doubt the most productive, protective, phenomenal environment, in that I personally felt like I had come home."
