The event comes as Hollywood mourns the death of Kirk Douglas, one of cinema's greats, who died Wednesday aged 103
Hollywood's award season reaches its extravagant finale at the Oscars on Sunday, with war epic 1917 tipped to dispatch a brigade of winners to the stage at the movie industry's biggest night.
The event comes as Hollywood mourns the death of Kirk Douglas, one of cinema's greats, who died Wednesday aged 103.
Sam Mendes's "1917" launched a late assault on this year's Academy Awards - it was first shown to voters barely two months ago - but experts predict it could outflank all rivals.
The World War I odyssey is about two soldiers crossing no-man's-land -- filmed to appear like one continuous shot.
It is the favorite for multiple Oscars from Best Director to Cinematography, and the frontrunner for Best Picture, the night's top prize.
"It falls into traditional Hollywood -- it's what the Oscars like," Variety awards editor Tim Gray told AFP.
"It's big, it's epic, but it's hardly a formula film. It really is a knockout... it's just film-making at its best."
The unique ballot system for Best Picture -- which involves voters ranking films -- makes it somewhat tough to predict, and could create an opening for an unlikely candidate.
Despite the best efforts of star film-makers Martin Scorsese ("The Irishman") and Quentin Tarantino ("Once Upon a Time... in Hollywood"), Mendes' main rival appears to be Bong Joon-ho, drawing unrivalled crowds at campaign events for his black comedy "Parasite."
The Oscars in the acting categories -- usually a subject of agonizing deliberation for industry pundits -- appear settled, with the same four stars sweeping up rave reviews and awards all season.
Joaquin Phoenix and Renee Zellweger are believed to be far ahead of the competition for Best Actor and Best Actress.
Tinseltown favourites Brad Pitt and Laura Dern have their fingertips on the supporting acting prizes, for their work as a laid-back stuntman ("Once Upon a Time... in Hollywood") and a cutthroat divorce lawyer ("Marriage Story").
"I see no scenario where any one of them loses," Deadline awards columnist Pete Hammond told AFP.
"People will say 'there's always an Oscars surprise'... but I think those four are going to win it," agreed Gray.
More fiercely contested will be the awards for Best Screenplay, Editing and Visual Effects, with movies from Nazi satire "Jojo Rabbit" to period drama "Little Women" and even superhero epic "Avengers: Endgame" all in the mix.
The ceremony will go on without a host for a second consecutive time, after last year's batch of bright guest presenters caused a trend-bucking uplift in TV ratings.
This year's presenter lineup is equally star-studded: Tom Hanks, Jane Fonda and Diane Keaton will appear alongside previous winners Brie Larson, Olivia Colman and Rami Malek.
Elton John, tipped to win the Best Original Song Oscar for "(I'm Gonna) Love Me Again" from "Rocketman," will perform, as will big Grammys winner and upcoming James Bond songstress Billie Eilish.
In a possible tip to the ongoing controversy over the lack of female nominees, Irish maestro Eimear Noone will become the first woman to conduct a segment of music during an Oscars telecast.
Cynthia Erivo was the only non-white acting nominee, for anti-slavery biopic "Harriet," and no women made the Best Director List.
"I wouldn't call it #OscarsSoWhite but I'd say it's #OscarsAsUsual," said Hammond.
"A British picture comes in at the end and wins a traditional kind of win, four white actors again. It looks like the Oscars could have been 30 years ago."
