"I am really amazed and stunned," said a clearly emotional Affleck, who directed the movie, which was set during the 1979 hostage crisis in Iran.
"We had more than 150 actors [in the cast.] They spoke in English, they spoke in Farsi. And the one thing they had in common was they came to work every single day, whether they had a line or a look to somebody or two lines or 10 lines or a bunch of stuff I couldn't understand in Farsi and they wanted to kill it because they wanted to make the movie better. Because that is what actors do all over the world. Every day. God bless you. Thank you so much for making the movies you make and the television you make and the theater you make. We are indebted to you," Affleck said.
"Thank you, thank you, thank you to all my brothers and sisters in the Screen Actors Guild," Day-Lewis said. "I'm very happy to be in this room with you tonight."
The double Oscar winner admitted he had some reservations about playing iconic U.S. President Abraham Lincoln.
"It occurred to me that it was an actor who murdered Abraham Lincoln and, therefore, somehow, it's only fitting that every now and then an actor tries to bring him back to life again," the British actor said. "I'm terribly proud to have been allowed to carry the baton for a while and now to pass it on. Everything flowed from [director] Steven Spielberg."
Jennifer Lawrence scooped up the Best Actress in a Film statuette for "Silver Linings Playbook" and
Anne Hathaway the Best Supporting Actress honor for "Les Miserables."
"This is incredible; thank you so much," said Lawrence, as she collected her prize for playing a troubled young widow who falls in love with a man recently released from a psychiatric hospital.
"I want to thank MTV [because of which] I earned my SAG card. When I was 14, I did an MTV promo for 'My Super Sweet 16' and I remembered getting [the card] in the mail and it being the best day of my entire life because it meant it made me officially an actor and put me in a category with all of you and now I have this naked statue that means some of you voted for me and that is an indescribable feeling," Lawrence said.
