LOS ANGELES (AP) ― Perhaps atoning for past sins, Hollywood named the brutal, unshrinking historical drama “12 Years a Slave” best picture at the 86th annual Academy Awards.

Steve McQueen’s slavery odyssey, based on Solomon Northup’s 1853 memoir, has been hailed as a landmark corrective to the movie industry’s long omission of slavery stories, following years of whiter tales like 1940 best-picture winner “Gone With the Wind.”

The British director dedicated the honor to those past sufferers of slavery and “the 21 million who still endure slavery today.”

“Everyone deserves not just to survive, but to live,” said McQueen, who promptly bounced into the arms of his cast. “This is the most important legacy of Solomon Northup.”

A year after celebrating Ben Affleck’s “Argo” over Steven Spielberg’s “Lincoln,” the Academy of Motion Picture Arts and Sciences opted this time for stark realism over more plainly entertaining candidates like the 3-D space marvel “Gravity” and the starry 1970s caper “American Hustle.”

Those two films came in as the leading nominee getters. David O. Russell’s “American Hustle” went home empty-handed, but “Gravity” triumphed as the night’s top award-winner. Cleaning up in technical categories like cinematography and visual effects, it earned seven Oscars including best director for Alfonso Cuaron. The Mexican filmmaker is the category’s first Latino winner.

“It was a transformative experience,” said Cuaron, who spent some five years making the film and developing its visual effects. “For a lot of people, that transformation was wisdom. For me, it was the color of my hair.” To his star Sandra Bullock, the sole person on screen for much of the lost-in-space drama, he said: “Sandra, you are ‘Gravity.’”

But history belonged to “12 Years a Slave,” a modestly budgeted drama produced by Brad Pitt’s production company, Plan B, which has made $50 million worldwide ― a far cry from the more than $700 million “Gravity” has hauled in. It marks the first time a film directed by a black filmmaker has won best picture.

Host Ellen DeGeneres, in a nimble second stint that seemed designed to be an antidote to the crude humor of Seth MacFarlane last year, summarized the academy’s options in her opening monologue: “Possibility number one: ‘12 Years a Slave’ wins best picture. Possibility number two: You’re all racists.”

DeGeneres presided over a smooth if safe ceremony, punctuated by politics, pizza and photo-bombing. Freely circulating in the crowd, she had pizza delivered, appealing to Harvey Weinstein to pitch in, and gathered stars to snap a selfie she hoped would be a record-setter on Twitter (It was: Long before midnight, the photo had been retweeted more than 2 million times). One participant, Meryl Streep, giddily exclaimed: “I’ve never tweeted before!”

But in celebrating a movie year roundly called an exceptional one, the Oscars fittingly spread the awards around. The starved stars of the Texas AIDS drama “Dallas Buyers Club” were feted: Matthew McConaughey for best actor and Jared Leto for best supporting actor.

McConaughey’s award capped a startling career turnaround, a conscious redirection by the actor to tack away from the romantic comedies he regularly starred in, and move toward more challenging films. He said he’s always chasing a better version of himself, his “hero”: “Every day, every week, every month of my life, my hero’s always 10 years away.”

“It sort of feels like a culmination,” he said backstage.

Leto passed around his Oscar to members of the press backstage, urging them to “fondle” it. The long-haired actor, who has devoted himself in recent years to his rock band 30 Seconds to Mars, gravely vowed: “I will revel tonight.” 

Cate Blanchett took best actress for her fallen socialite in Woody Allen’s “Blue Jasmine,” her second Oscar. Accepting the award, she challenged Hollywood not to think of films starring women as “niche experiences”: “The world is round, people!” she said to hearty applause.

Draped in Nairobi blue, Lupita Nyong’o ― the Cinderella of the awards season ― won best supporting actress for her indelible impression as the tortured slave Patsey. It’s the feature film debut for the 31-year-old actress.

“It doesn’t escape me for one moment that so much joy in my life is thanks to so much pain in someone else’s, and so I want to salute the spirit of Patsy for her guidance,” said Nyong’o. She also thanked director Steve McQueen: “I’m certain that the dead are standing about you and they are watching and they are grateful, and so am I.”

Though the ceremony lacked a big opening number, it had a steady musical beat to it. To a standing ovation, Bono and U2 performed an acoustic version of “Ordinary Love,” their Oscar-nominated song from “Mandela: Long Walk to Freedom,” a tune penned in tribute to the late South African leader Nelson Mandela. Singing his nominated “Happy” from “Despicable Me 2,” Pharrell Williams had Streep and Leonardo DiCaprio dancing in the aisles.

Pink was cheered for her rendition of “Somewhere Over the Rainbow,” part of a 75th anniversary tribute to “The Wizard of Oz.” And Bette Midler sang ― what else? ― “Wind Beneath My Wing” for the in memoriam segment ― an especially heartfelt one, considering the deaths of Philip Seymour Hoffman, Harold Ramis, James Gandolfini and others.

Best documentary went to the crowd-pleasing backup singer ode “20 Feet From Stardom.” One of its stars, Darlene Love, accepted the award singing the gospel tune “His Eye Is on the Sparrow”: “I sing because I’m happy/ I sing because I’m free.”

Disney’s global hit “Frozen” won best animated film, marking ― somewhat remarkably ― the studio’s first win in the 14 years of the best animated feature category. (Pixar, which Disney owns, has regularly dominated.) With a box-office record that recently passed $1 billion globally, the film was sure to be the biggest hit to take home an Oscar on Sunday. The film’s “Let It Go” won best original song.

“We’re all just trying to make films that touch people,” said co-director Chris Buck backstage. “Once in a while, you get lucky.”

Though the Oscar ceremony is usually a glitzy bubble separate from real-world happenings, international events were immediately referenced. In his acceptance speech, Leto addressed people in Ukraine and Venezuela.

“We are here and as you struggle to make your dreams happen, to live the impossible, we’re thinking of you,” said Leto.

Russian state-owned broadcaster Channel One Russia said it would not broadcast the Oscars live because of the necessity for news coverage of Russia’s invasion of Ukraine’s Crimea peninsula. It will instead transmit the Oscars early Tuesday morning, local time.
