Set production and television news crews got an early start on Sunday (March 10) morning, putting finishing touches on the famed red carpet before Hollywood's glitterati arrive for the 96th Academy Awards.

Television reporters and production crews were already broadcasting live at 5am Pacific Time (1200 GMT), filming stand-ups and other on-camera promotions, while outside workers ironed and stapled the carpet into its final place.

"Oppenheimer," the three-hour drama directed by Christopher Nolan, leads the field with 13 nominations. The movie is the frontrunner to win the prestigious best picture prize, capping its sweep of other major awards this year.

After 2023 was marred by actors and writers strikes, the Oscars give Hollywood a chance to celebrate two global hits. "Oppenheimer" and feminist doll adventure "Barbie," another best picture nominee, brought in a combined $2.4 billion in a summer box office battle dubbed "Barbenheimer."

Oscar producers said they have planned unannounced cameos and other surprises to entertain audiences at home.

Talk show host Jimmy Kimmel returns for the fourth time to emcee the film industry's highest honors from the Dolby Theatre in Los Angeles. The live broadcast on ABC starts at 4 p.m. PDT (2300 GMT), an hour earlier than usual.
