Five things to watch for on Oscars night

Will Alfonso Cuaron sweep the awards for his cinematic masterpiece “Roma?” Will another contender swipe the best picture Oscar from him? Can Glenn Close finally claim her first Academy Award?

The ceremony will be without a host for the first time in three decades — a fact sure to create some surprising moments.

Here are five things to watch for on Sunday when the stars gather for the 91st Oscars:

– Can Netflix’s ‘Roma’ make history? –

Streaming giant Netflix could take a major step forward in its quest to be both a distribution king and a purveyor of quality original content if “Roma” becomes its first film to take home a best picture Oscar.

“Roma” earned a whopping 10 nods, leading the proceedings in a tie with “The Favourite.” The film earned nominations in several top categories including best director and best actress, also a new high for Netflix.

Amazon Studios already broke through in the best picture category in 2017 with a nomination for “Manchester by the Sea” — but did not grab the win.

A best picture victory for “Roma” would also make history as it would be the first foreign-language film to do so.

And it would be the crown jewel in a rich awards season for Alfonso Cuaron, whose black-and-white film pays homage to his mother, his nanny and his childhood in 1970s Mexico City.

Four of the 10 nominations for “Roma” are his: for best picture as a producer, best director, best original screenplay and best cinematography.

He joins illustrious company with his achievement: Warren Beatty did the same, scoring four nominations in four different categories — twice — for “Heaven Can Wait” and “Reds.”

Joel and Ethan Coen did it for “No Country for Old Men.”

– At last, Glenn Close’s turn? –

Glenn Close is a veteran stage and screen actress and is revered by her peers. She is a winner of three Emmys, three Golden Globes and three Tony Awards. But Oscar has never smiled on her.

This year, with her seventh nomination, could finally be her year.

Close, 71, earned rave reviews for her portrayal of Joan Castleman, a woman who finds herself at a crossroads in her marriage to an author husband in “The Wife,” opposite a formidable Jonathan Pryce.

She has swept the major prizes so far this awards season, from a Golden Globe in January to a Screen Actors Guild prize to the Critics’ Choice Award she shared with Lady Gaga.

Oscarologists are near-unanimous in their prediction that Close will strike gold on Sunday. We’ll see when the envelope is opened.

– What about Spike Lee? –

Spike Lee is still bitter about what is perceived as one of the most egregious Oscar snubs: the choice of “Driving Miss Daisy” for best picture in 1990, when his “Do The Right Thing” was not nominated.

But this year, his “BlacKkKlansman” is up for six Oscars, and Lee himself was nominated three times: for best picture as a producer, best director and best adapted screenplay

Lee was given a honorary Oscar a few years ago for lifetime achievement but has never taken home a competitive Academy Award. Many hope his tale of a black cop who infiltrated the Ku Klux Klan will break the unhappy streak.

– Is a hostless Oscars a better Oscars? –

For the first time in 30 years, the Oscars will go on without a host. The Academy of Motion Picture Arts and Sciences initially offered the job to Kevin Hart, but backlash over a series of old tweets quickly ended that.

So gala organizers are going without an emcee for the first time since 1989 — a disastrous year remembered for a musical duet between actor Rob Lowe and … Snow White.

Will the hostless gala mean a shorter gala, which many viewers and industry A-listers have asked for? Organizers have promised to try to keep the show at about three hours. We’ll see.

– A-list music performances –

Lady Gaga, Queen with Adam Lambert, Bette Midler: some of music’s biggest stars will be front and center on Oscars night to perform Oscar-nominated songs, and otherwise entertain the A-listers.

Gaga and Bradley Cooper will sing their power ballad “Shallow” from “A Star Is Born” live for the first time on television.

Midler will do “The Place Where Lost Things Go” from “Mary Poppins Returns,” and Oscar winner Jennifer Hudson will sing the theme song “I’ll Fight” from the documentary “RBG” about Supreme Court Justice Ruth Bader Ginsburg.

Also added to the schedule were Queen — “Bohemian Rhapsody,” the story of the band’s rise to fame, earned five nominations including for best picture and best actor (Rami Malek as the late Freddie Mercury).

Kendrick Lamar and SZA had been due to perform their song “All the Stars” from “Black Panther,” but Variety reported that they would not attend, citing a “logistics and timing” issue.
