After four previous acting nominations spanning 22 years, The Revenant star Leonardo DiCaprio was finally crowned Best Actor at the Oscars on Sunday night. Mad Max: Fury Road won six awards, while Spotlight was the surprise Best Picture winner.

Accepting his award, DiCaprio saluted the other Best Actor nominees this year, which included Michael Fassbender for his performance in Steve Jobs. He thanked his parents and all the others who had helped him throughout his career. 

DiCaprio also used his acceptance speech to highlight climate change and "man's relationship to the natural world". "Let us not take this planet for granted. I do not take tonight for granted," he said. 

Brie Larson won Best Actress for her performance in the Irish film Room, directed by Lenny Abrahamson. In her acceptance speech she described the Dublin filmmaker as "absolutely incredible" and also paid tribute to Irish author Emma Donoghue, who adapted her own bestseller for the screen. Saoirse Ronan had been nominated in the Best Actress category for her performance in Brooklyn.

Irish films Brooklyn and Room lost out in the Best Adapted Screenplay category, with The Big Short's Charles Randolph and Adam McKay winning the award. Room author Emma Donoghue had been among the Best Adapted Screenplay nominees, and was joined in that category by English writer Nick Hornby, who adapted Colm Tóibín's Brooklyn for the big screen.

Stutterer, which was directed by Irishman Benjamin Cleary, was named Best Live Action Short. Accepting the Oscar, Cleary said: "Every day is a proud day to be Irish, but today even more so...Sláinte!"

The Revenant's director, Alejandro González Iñárritu, won his second Best Director Oscar in a row - he won last year for Birdman. Dublin filmmaker Abrahamson had been nominated in the category for Room.

Along with Spotlight's win, the other big shock of the night was Creed star Sylvester Stallone losing out in the Best Supporting Actor category to Mark Rylance for Bridge of Spies

"I've always just adored stories," Rylance said in his acceptance speech. "It's a wonderful time to be an actor and I'm proud to be a part of it." 

Alicia Vikander won Best Supporting Actress for The Danish Girl. She thanked her parents "for giving me the belief anything can happen".

After five previous nominations, composer Ennio Morricone finally won for his work on The Hateful Eight. He was the recipient of an honorary award in 2007.

The Revenant's Emmanuel Lubezki won his third Cinematography Oscar in as many years. He previously won for Birdman and Gravity.

Host Chris Rock made the most of the #OscarsSoWhite controversy with his jokes on the night, describing the ceremony as the "White People's Choice Awards".

The show also saw special guest appearances by Star Wars: The Force Awakens trio BB-8, C-3PO and R2D2.
