At an event where no single film dominated, Alejandro Inarritu of Mexico won the best directing Oscar for "The Revenant," making him the first filmmaker in over 60 years to win back-to-back Academy Awards. Inarritu previously won in 2015 for "Birdman." "The Revenant" entered the ceremony with 12 nominations and was one of four films considered favorites for best picture after winning Golden Globe and BAFTA awards. The ambitious 20th Century Fox film, set in the Pioneer era and filmed in freezing temperatures, also earned Leonardo DiCaprio his first Oscar win, receiving a standing ovation from the Hollywood audience. DiCaprio used his acceptance speech to call for action on climate change, stating, "I do not take tonight for granted." Voters in the Academy of Motion Picture Arts and Sciences selected Open Road Films' "Spotlight" as the best picture, a film that follows the Boston Globe's award-winning investigation into child sex abuse by Catholic priests in 2003. The movie also won for best original screenplay. During his acceptance speech, producer Michael Sugar stated that the film gave a voice to survivors and expressed his hope that the Oscar win would help amplify that voice, reaching all the way to the Vatican. Brie Larson, a rising star at 26, won the award for best actress for her performance in "Room," further adding to her collection of trophies. The show featured racial themes and criticism of the lack of diversity in the acting nominee line-up for the second year in a row, with host Rock calling it "the white People's Choice awards." He pointed out the irony of the industry's sudden focus on diversity, questioning why it hadn't been addressed decades ago when black Americans were facing more serious issues like rape and lynching. Rock also visited Compton to ask residents about the Oscar-nominated movies. No one had anything negative to say. Many nominees praised Rock for addressing a difficult topic effectively. Adam McKay, director and co-writer of "The Big Short," thought Rock's approach was critical of Hollywood while remaining fair and addressing diversity in a new way. McKay found it impressive and humorous. Rock was not the only one shining a light on people of color at the Oscars. Alejandro Inarritu, who won the Best Director award for "The Revenant," expressed gratitude for his win and acknowledged the lack of opportunity for others. He hoped for a future where skin color would be as inconsequential as hair length. Mark Rylance surprised by beating Sylvester Stallone for Best Supporting Actor for "Bridge of Spies," but he praised Stallone and called him the true winner. Arnold Schwarzenegger, a fellow action star, expressed his pride in a brief video posted online. Sam Smith's theme song for the James Bond movie "Spectre" won over Lady Gaga's ballad "Til It Happens to You," which raises awareness about sexual assault. Alicia Vikander won the supporting actress Oscar for her role in the transgender movie "The Danish Girl," while the documentary "Amy" about the late Amy Winehouse also received an award. "Mad Max: Fury Road" from Warner Bros was the top winner with six Oscars in technical categories like costume, make-up, and editing.
