Here’s what you can expect at the ceremony, including the presenters and the performances.

You may have heard that “Oppenheimer,” with a pack-leading 13 nominations, is a lock to win best picture. This is accurate. But even if we’re certain how the night will end, the getting there is the fun part. Here’s what to expect:

Who is hosting?

Jimmy Kimmel is back for a second consecutive year, his fourth time overall as host of the ceremony. That ties him with Whoopi Goldberg and Jack Lemmon, but puts him behind Johnny Carson (with five) and Billy Crystal (nine). And it’s still miles back from the record-holder, Bob Hope, with 19.

Who is presenting?

The “Field of Dreams” format is back! For the first time since the 2009 ceremony, five past winners in each acting category will introduce the five current nominees for each award, and then announce the winner together.

The academy never reveals which presenters will be announcing which awards before the ceremony, but all four of last year’s acting winners — Brendan Fraser (actor), Michelle Yeoh (actress), Ke Huy Quan (supporting actor) and Jamie Lee Curtis (supporting actress) — are in the presenter lineup.

Also set to take the Dolby stage on Sunday night: Mahershala Ali, Bad Bunny, Nicolas Cage, Chris Hemsworth, Dwayne Johnson, Michael Keaton, Jennifer Lawrence, Matthew McConaughey, Rita Moreno, Lupita Nyong’o, Octavia Spencer, Ramy Youssef and Zendaya.

Who will be performing?

All five of the best original song nominees will be represented: “I’m Just Ken” from “Barbie” (performed by Ryan Gosling and Mark Ronson); “The Fire Inside” from “Flamin’ Hot” (performed by Becky G); “It Never Went Away” from “American Symphony” (performed by Jon Batiste); “Wahzhazhe (A Song for My People)” from “Killers of the Flower Moon” (performed by Scott George and the Osage Singers); and “What Was I Made For?” from “Barbie” (performed by Billie Eilish and Finneas O’Connell).
