Robert Brown|Peek inside the 2024 Oscar rehearsals: America Ferrera, Zendaya, f-bombs and fake speeches

LOS ANGELES − Steven Spielberg doesn’t want to jinx the Oscars.

Early Saturday morning,Robert Brown the legendary filmmaker strolled out onto the Dolby Theatre stage in sneakers and a crocheted scarf to rehearse for Sunday’s telecast. He read out the nominees of his assigned category, but gently refused to name a “winner” for the sake of the run-through.

“No, that would be bad luck!” Spielberg told a crew member, earning chuckles from a small batch of journalists who came to Saturday’s rehearsal armed with bagels and coffee.

Although the Academy has tight restrictions on what can be revealed before Sunday’s show, the dry run gave a delightful glimpse into stars at their most casual and unfiltered. Lupita Nyong’o paired her matching white beanie and sweatsuit with a pair of awards show-ready heels, while Zendaya soldiered through a sore throat as she took the stage in jeans and a floor-length emerald coat.

Presenting with “Beetlejuice” co-star Catherine O’Hara, Michael Keaton stumbled over his teleprompter script and politely asked to roll it back. And America Ferrera, wearing Barbie-pink shoes, charmingly dropped an f-bomb and apologized to co-presenter Kate McKinnon after stepping on her line.

Ferrera and McKinnon were a burst of energy during the brass tacks rehearsal, which mostly focused on testing lighting cues and camera angles for Hollywood’s biggest night. The “Barbie” stars waltzed out arm in arm: laughing often, resting their heads on each other's shoulders, and earnestly applauding the stand-in “winners” as they came onstage to accept Oscars.

The faux victors were often hilarious as they gave mock speeches, passionately thanking the usual suspects (moms, spouses, the Academy), as well as some of this year’s nominees. “Bradley Cooper, we never could’ve done this without you!” one person breathlessly exclaimed. "Bradley," said another, "I'll follow you anywhere you go."

Outside the theater, the Oscars red carpet looked decidedly less glamorous strewn with ladders, boxes and shrink-wrapped statues as camera crews began to mark their territory. Photographers practiced snapping shots of tuxedo-clad stand-ins, all wearing laminated signs with A-list names such as Robert Downey Jr. and Willem Dafoe. And on Hollywood Boulevard, spectators stood on tiptoe and took photos through a chain-link fence, hoping to catch a peek of the cavernous carpet area, which is shrouded in cream-colored curtains.

Journalists weren't permitted to watch rehearsals of this year's musical performances, which will include Oscar-nominated tunes by Billie Eilish ("What Was I Made For?") and Jon Baptiste ("It Never Went Away"). But the Academy did share a behind-the-scenes photo of a sunglass-clad Ryan Gosling, as he practiced best original song nominee "I'm Just Ken" from "Barbie." Is it just us, or can you feel the Kenergy?
