Some of the attendees were playing double duty.
"Don't forget I'm still an actor," said Argo director/producer/star Ben Affleck, joking that he's really just networking to land his next gig. "I'm hoping to lobby -- remind them."

"I'm very lucky tonight to be able to present [the David O. Selznick Achievement Award] to Tim Bevan and Eric Fellner, who produced Les Miserables," said Hathaway. "It's an honor."
