'Oppenheimer' dominates at the 2024 Oscars

Da’Vine Joy Randolph has won the first award of the night: the Oscar for best actress in a supporting role.

Randolph won the honor for her role in the film "The Holdovers."

In “The Holdovers,” Randolph delivers a heartbreaking performance as Mary Lamb, a boarding school cook in 1970 who is grieving her recently deceased son who was fighting in the Vietnam War. 

Randolph costars with Paul Giamatti and Dominic Sessa in the acclaimed Alexander Payne-directed film about people “holding over” at their snowy New England school with nowhere else to go during the holidays. 

This post has been updated with more details from Randolph's speech and about the movie.

Tonight's red carpet marked the beginning of what could well be another epic “method dressing” press tour — this time starring the cast of "Wicked." Cynthia Erivo wore a bewitching green custom leather Louis Vuitton gown with structured ruffle sleeves and train as a nod to her character Elphaba, while her co-star Ariana Grande wore a voluminous bubblegum pink gown by Giambattista Valli, perfect for the good witch Glinda.

We’ve seen the cast of "Dune: Part Two" go all out in recent weeks with their looks on the media circuit, with countless looks from Timothée Chalamet, Zendaya and Florence Pugh channelling the movie. (And though she may have showed up tonight dressed in black, the collection of classic Barbie doll-inspired looks put together by stylist Andrew Mukamal for Margot Robbie on the "Barbie" press tour were an always-apt embodiment of being pretty in pink.)

Jimmy Kimmel included Messi, the dog from "Anatomy of a Fall," in his Oscars monologue, and the camera panned to the animal as he sat next to his companion.

Kimmel praised Messi for his acting during a drug overdose scene in the French movie.

The stars have made their way from the red carpet to their seats and Hollywood's biggest night is underway at the Dolby Theatre in Los Angeles.

We'll bring you live updates on host Jimmy Kimmel's opening monologue, award winners, performances and more big moments from the show.

Kimmel opened the show with a short, pre-recorded sketch featuring "Barbie" star Margot Robbie, then took the stage to applause.

Kimmel took the place of the elder woman on the bench from a scene in the film, saying "I know," in response to Margot Robbie telling him, "You're beautiful."

"I haven't eaten in three weeks," he replied, saying he had to go host the Oscars.

This post has been updated with details from the start of the show.

The stars have arrived at the Dolby Theatre for Hollywood’s biggest night: the Oscars. As well as celebrating the year in movies, the annual extravaganza has long been the red carpet event of the year.

The 96th Academy Awards ceremony marks the culmination of a months-long awards season that has seen plenty of florals, cut-outs, sequins and sheer gowns. (And it’s not just Margot Robbie who’s contributed pops of “Barbie”-worthy pink.) But many of the night's attendees — or perhaps the designers and stylists who dress them — have clearly been saving their best for last.

The Awards’ categories are filled with stars who have produced moments of red carpet magic in recent months, from Colman Domingo (pictured above) and America Ferrera to Best Song nominee Billie Eilish. So too is the list of presenters and performers, which include Bad Bunny and Zendaya, among many others. Click through to CNN Style's recap of the red carpet to see all the best looks.

Jimmy Kimmel and the biggest movie of last year.

The later night talk show host kicked off his hosting appearing in a scene from "Barbie" which won both the box office and the hearts of moviegoers.

He also paid tribute to the film's director, Greta Gerwig, who made headlines when she wasn't nominated in the best director category.

Kimmel reminded those in the audience that they were the ones responsible for that.

He also teased many others in the audience including Margot Robbie, Ryan Gosling, Christopher Nolan, Robert Downey Jr., Robert De Niro, Jodie Foster, Bradley Cooper and even the dog Messi, who is one of the stars of "Anatomy of a Fall."

He also received all the love from the audience.

Kimmel pointed out that while the show began an hour earlier this year, folks can't count on it not ending late. "In fact, we are already 5 minutes over and I am not joking."

He got plenty of laughs in his opener as he weaved in everything from the actors' and writers' strikes to the abundance of award-nominating worthy projects.

He even brought out a group of people who represented those behind the scenes like the Teamsters and others who stood beside the strikers. He encouraged them to "Take a bow" and vowed to stand with them should they strike.

The 96th Academy Awards will take place Sunday and while the gowns and the guests will be beautiful, we’ll be watching to get in our feelings with moving acceptance speeches.

Honestly, the crazier or more emotional, the better.

Let’s look back at some of the more unforgettable Oscars speeches from ceremonies in recent decades.

Roberto Benigni, “Life is Beautiful” (1999): When the director and actor won the Oscar for best foreign language film in 1999, he jumped up, walked over neighboring chairs, clutched Steven Spielberg’s hand along his path, then, quite literally, bounced his way to the stage to yell:

Rewatching video of the moment is an instant mood boost.

Leonardo DiCaprio, “The Revenant” (2016): DiCaprio used his moment in the spotlight to urge people to work together to address the threat of climate change.

Lupita Nyong’o, “12 Years a Slave” (2014): There were few dry eyes in the audience when Nyong’o won for her performance in the drama “12 Years a Slave.” Her poignant speech concluded with a powerful message.

Annette Bening is meeting the moment.

The acclaimed actor is currently in the midst of her fifth campaign for an Oscar statuette, this time for her intense and very physical performance in “Nyad,” based on the life of legendary and determined swimmer Diana Nyad.

Bening isn’t, however, considered the favorite to win this year. When asked during a recent interview with CNN about whether she’s as mad about that fact as some of her supporters are, she laughed heartily.

Bening maintains that when it comes to the entertainment business, “you have to have a sense of humor about it.”

“One of the good things about this moment for me is that I can look back at 34 years ago when I first went to the Oscars and what that was like, and compare it to this time, so it does give me a certain perspective that allows me to just go with the flow,” she said. “I don’t really worry. I just am appreciative.”

Bening is referring to her first Academy Award-nominated role in 1990’s “The Grifters,” the Stephen Frears-directed crime drama in which she starred opposite John Cusack and Anjelica Huston. It was one of her first film roles, but Bening stole the spotlight and was soon landing lead roles, like in “Bugsy” (opposite her future husband Warren Beatty) and “The American President.”

Actress and singer Hailee Steinfeld has arrived on the red carpet, looking ethereal in a sea foam green Elie Saab Couture gown with golden floral embellishments on the bust and wrists, and a trailing floor-length neck sash.

As a teen, Steinfeld was nominated for the best supporting actress Oscar for her role in 2011's "True Grit."

Steinfeld's is one of a number of looks on the red carpet channeling mermaid chic, including Anya Taylor-Joy’s Dior Haute Couture dress (inspired by Botticelli’s "Birth of Venus," the actor explained) and Emma Stone’s shell-inspired custom Louis Vuitton gown with a flared peplum waist.
