(LOS ANGELES) -- The big winner at Sunday's Academy Awards turned out to be The King's Speech, as the movie took home four awards on the night, including the award for best picture.
Natalie Portman won her first Oscar Sunday night, taking best actress honors for her role in Black Swan, while Colin Firth contributed to the tally for The King's Speech by winning the award for best actor.
In a self-deprecating and emotional speech, Firth joked, "I have a feeling my career has just peaked." With his typical British reserve, he said he was "experiencing stirrings" that were "threatening to turn into dance moves."
Firth thanked his wife, Livia, for the award and "everything good in my life," while the pregnant Portman thanked "my love," her fiancee and Black Swan choreographer Benjamin Millipied for giving "me my most important role of my life."
Tom Hooper, the director of The King's Speech, pulled off a surprising win over The Social Network director David Fincher. Speech, which led the number of nominations with 12, also won the award for best original screenplay, while The Social Network grabbed the gold statue for best adapted screenplay.
The Fighter co-stars Melissa Leo and Christian Bale were among the early winners, receiving Oscars for best supporting actress and best supporting actor.
Leo got the night off to a raucous beginning, when she dropped the F-bomb during her speech. When Bale accepted his award, he told the audience, "I'm not going to drop the F-bomb, like she did. I've done that plenty before." Both were expected to win after taking home the same awards at the Golden Globes. But some doubt had been cast on Leo, after the ads she took out in the Hollywood trades promoting herself backfired. Still, Leo pulled off the win in the end.
"This has been an extraordinary journey," Leo said about the award season. "It's about selling motion pictures and respecting the work."
Among those thanked by Bale in his acceptance speech was Dicky Ecklund, the washed-up fighter he played in The Fighter.
President Barack Obama made a surprise appearance at the Oscars. During an introduction for best song, he cited "As Time Goes By" from Casablanca as his favorite movie theme song.
Later in the telecast, Randy Newman, who has been nominated 20 times and won once previously, received the Oscar for "We Belong Together" from Toy Story 3. Tim Burton's Alice in Wonderland took home the first Oscar for art direction. Cinematographer Wally Pfister won his first Oscar for Inception, and gave credit to Christopher Nolan, who was snubbed for a best director nomination. Inception took home several technical awards, for sound mixing, sound editing and visual effects. Pfister beat out perpetual nominee Roger Deakins, the cinematographer on True Grit. Deakins has yet to win an Oscar.
Toy Story 3, which was also nominated for best picture, won best animated feature.
