Steven Spielberg didn't want to "get in the way" of Daniel Day-Lewis' "amazing" acting in 'Lincoln'.

The 65-year-old director chose not to question the 'Gangs of New York' star, who portrays former US President Abraham Lincoln in the film, nor screenwriter Tony Kushner, when the movie was being created because he preferred to "celebrate" their work.

He said: "I think Daniel, like Tony Kushner, understood Lincoln on a subatomic level, one that goes beyond anything I could articulate. I never asked Daniel about his process, I never questioned it; I never looked the gift horse in the mouth. I just received it with tremendous gratitude.

"With Daniel and Tony, I felt I was in between two giant figures in the landscape of theatre and performances and I was constantly saying to myself, 'Don't get in the way; celebrate these words, capture these performances, get it in the best way you know how.' And let the actors cast their long shadows. He's amazing."

While Steven loved Tony's screenplay for 'Lincoln' - which is based on the best-selling book 'Team of Rivals' by historian Doris Kearns Goodwin - he had to cut down his first effort as it was nine hours long.

He added to FlicksandBits.com: "When I got into the screenplay it was one of the most brilliant things I've ever read, but it was sprawling and epic and it was nine hours long, it was just impractical as a motion picture."
