NEW YORK — Oscar voters on Tuesday showered Alfonso Cuaron’s “Roma” and Yorgos Lanthimos’ “The Favourite” with a leading 10 nominations for the 91st Academy Awards, while two dominant but contentious Hollywood forces — Netflix and Marvel — each scored their first best picture nomination.

Though many expected “A Star Is Born,” Bradley Cooper’s revival of one of Hollywood’s most remade show business myths, to top the nominations, Cooper was surprisingly overlooked as director and the Academy of Motion Pictures Arts and Sciences instead put its fullest support behind a pair of indies by international directors.

With the black-and-white, Spanish-language “Roma,” Netflix scored its first best picture nomination, a prize the streaming giant has dearly sought. Marvel, too, joined the club with Ryan Coogler’s “Black Panther,” the first superhero movie ever nominated for best picture.

Cuaron tied the record for most decorated Oscar nominee ever for one film with four individual nods for “Roma,” his deeply personal exhumation of his Mexico City childhood. Cuaron was nominated for direction, cinematography, original screenplay and best picture. Only Orson Welles (“Citizen Kane”) and Warren Beatty (who did it twice with “Reds” and “Heaven Can Wait”) have matched the four-nod feat.

Cuaron, previously a six-time nominee and winner for directing “Gravity,” said by phone from London that the nominations for such a personal film were more meaningful to him, as was the attention for a film about a humble indigenous domestic worker (Yalitza Aparicio, who was nominated for best actress). He praised Netflix for its commitment to his film.

“Cinema needs the opportunity to be diverse,” Cuaron said. “What mainstream cinema and the theatrical experience has lacked in general is diversity. And I’m talking about diversity in terms of stories and characters and ways of doing films.”

Just as rewarded Tuesday was Lanthimos’ period romp, which resounded most in the acting categories thanks to its trio of actresses: Olivia Colman in the best actress category, and Rachel Weisz and Emma Stone in supporting.

Along with “Roma,” “Black Panther” and “The Favourite,” the eight nominees for best picture were: Peter Farrelly’s interracial road trip tale “Green Book,” Spike Lee’s white supremacist evisceration “BlacKkKlansman,” the Freddie Mercury biopic “Bohemian Rhapsody,” Adam McKay’s highly critical Dick Cheney biopic “Vice” and “A Star Is Born,” which still landed eight nominations, including best actress for Lady Gaga and best supporting actor for Sam Elliott.
