No one knew what to expect when Jack Nicholson announced that a special guest would join him to present the award for Best Picture during Sunday's Oscar ceremony.

But then the Dolby Theatre erupted into applause when First Lady Michelle Obama accompanied Nicholson onstage.

"[These films] taught us that love can beat all odds," said Mrs. Obama of the Best Picture nominees. "They reminded us that we can overcome any obstacle if we dig deep enough and fight hard enough and find the courage within ourselves."

The First Lady added that cinema "helps our children learn to open their imagination and dream just a little bigger and to strive every day to reach those dreams."

"Argo" won the award, and an emotional Ben Affleck ended his acceptance speech by saying, "It doesn't matter how you get knocked down in life, all that matters is how you get back up."
