Ben Affleck's 'Argo' Wins Oscar for Best Picture
"Argo," directed by Ben Affleck has won the prize for best picture at the 85th Oscar awards Sunday.
The glamorous ceremony, held at the Dolby Theater in Los Angeles, was hosted by Seth MacFarlane.
At the start of the ceremony he joked: "Argo's story is so top-secret that its director remains unknown to the Academy," referring to Affleck's omission from the best director category.
"Argo" is the first best picture winner not to be nominated for best director since 1989's "Driving Miss Daisy."
Accepting his award alongside fellow producers George Clooney and Grant Heslov, Affleck paid tribute to the "genius" Steven Spielberg whose film, "Lincoln," lost out in the same category.
"I never thought I would be back here and I am because of so many of you who are here tonight. It doesn't matter how you get knocked down in life, all that matters is that you get up," BBC quoted him saying, referring to his previous Oscar success with 1997's Good Will Hunting.
Daniel Day-Lewis won the best actor prize for his role in "Lincoln."
The British-born actor made Oscar history by becoming the first to win the best actor prize three times.
"I really don't know how any of this happened. I do know I've received much more than my fair share of good fortune in my life," he said.
