Hollywood’s biggest stars walked the world’s most famous red carpet Sunday to attend the 88th Academy Awards ceremony, the film industry’s highest honors.

This year’s show, hosted by comedian Chris Rock, has been marked by controversy regarding the lack of diversity of its nominees. For the second year in a row, only white actors and actresses were chosen for the top four categories — best actor/actress and best supporting actor/actress.

The resulting backlash led to several African-American actors and actresses, such as Spike Lee and Jada Pinkett Smith, boycotting the event and the rise of the social media hashtag #OscarsSoWhite.

Rock opened the show with caustic jokes about the controversy.

“I’m here at the Academy Awards, otherwise known as the white People’s Choice awards. You realize if they nominated hosts, I wouldn’t even get this job. You’d be watching Neal Patrick Harris right now.”

Harris, who is white, hosted the event last year. The last black host was Rock himself in 2005.

The 51-year-old Rock also got serious during his opening monologue.

“We want opportunities,” he said. “We want black actors to get the same opportunities, that’s it,” he said to rousing applause.

Best Picture

 “Spotlight” a film about the Boston Globe’s Pulitzer Prize-winning investigation into child sex abuse by Catholic priests won the oscar for Best Picture.

Best Director

 

Alejandro G. Inarritu won the oscar for Best Director for “The Revenant”, this year’s most nominated film, featuring Leonardo DiCaprio as a fur trapper who almost dies after being mauled by a bear.

“I am very lucky to be here tonight but unfortunately many others haven’t had the same luck,” he said during his acceptance speech, referring to the diversity controversy.

 

Best Original Song

Jimmy Napes and Sam Smith won the oscar for Best Original Song for “Writing’s on The Wall” from the movie Spectre”.

“I stand here today as a proud gay man,” Smith told the audience, dedicating his award to the LGBT community.

 

 

Smith and Napes beat out Lady Gaga who along with Diane Warren wrote the song “Til It Happens to You”, from the film “The Hunting Ground”, an expose on rape crimes on U.S. college campuses. 

U.S. Vice President Joe Biden made a surprise appearance at Sunday night’s show where he asked people to pledge to intervene in sexual encounters when consent has not been given.  He then introduced Lady Gaga who sang “Til It Happens to You”.

Best Foreign Language Film

The film “Son of Saul” from Hungary won the oscar for Best Foreign Language film.

Best Supporting Actor, Actress

First-time nominee Mark Rylance won the oscar for Best Actor in a Supporting Role for his performance in “Bridge of Spies” in which he played a Russian operative.  During his acceptance speech, which was cut short, he praised co-star Tom Hanks and director Steven Spielberg.

The award for Best Actress in a Supporting role went to 27-year-old Sweden-born actress Alicia Vikander for her performance in “The Danish Girl.”

The South American country of Chile won its first oscar in the Best Animated Short Film category for “Bear Story” – which Gabriel Osorio and Pato Escala accepted.

Oscar first – Girl Scout Cookies

In what was undoubtedly a first at this year’s show, host Chris Rock asked the audience to reach into their “millionaire pockets” and buy some Girl Scout cookies to help his daughters sell a record amount this year. 

Girl Scouts armed with cookies circulated throughout the audience who were holding up money to buy the cookies.

First award of the night

The first award of the evening went to the film “Spotlight” for Best Original Screenplay.

More than 40 million people worldwide are expected to be watching the ceremony.

Protests

Protesters urging a boycott of the Academy Awards congregated near the Dolby theatre where the awards were being presented Sunday.

Dozens of protesters converged on the corner of Sunset Boulevard and Highland Avenue, holding signs and calling for more diversity in feature films.

Some of the signs included the slogans, “Hollywood Must do Better” and “Shame on You.”
