LOS ANGELES — Happy Oscars Sunday to all who celebrate.

Conan O’Brien kicked off the 98th Academy Awards Sunday night with a montage of clips from Best Picture nominees while taking on Amy Madigan’s Aunt Glady from “Weapons” as kids ran behind him.

O’Brien didn’t wait to hold back. He instantly joked about a Waymo hosting next year’s ceremony in a tux. He took a swing at Timothée Chalamet’s recent controversial remarks about opera and ballet. 

What else can we expect at this year’s ceremony?

No awards show is complete without a musical performance. 

Miles Caton and Raphael Saadiq performed “I Lied to You,” the nominated original song from “Sinners.” They were joined by a bevy of performers onstage — Misty Copeland, Eric Gales, Buddy Guy, Brittany Howard, Christone “Kingfish” Ingram, Jayme Lawson, Li Jun Li, Bobby Rush, Shaboozey and Alice Smith among them — for a near-recreation of the scene in “Sinners” where the song is introduced.

It is one of the more memorable moments in the film, where a blues song in a Mississippi juke joint opens up to showcase hip-hop DJs, rock ‘n’ roll guitarists, ballerinas and more, illustrating the Black music genre’s place at the foundation of American popular culture.

When the live tribute performance to “Sinners” wrapped on stage, there was a slew of applause, some of which came from people who stood for the ovation.

One of the most highly expected reunions of the night will be the cast of “Bridesmaids.” Melissa McCarthy, Kristen Wiig, Rose Byrne, Ellie Kemper and Maya Rudolph will come together to celebrate the film’s 15-year anniversary.

Did we get a “The Devil Wears Prada” reunion? Sort of … Anna Wintour and Anne Hathaway teamed up to present the costume design and make and hairstyling Oscars.

Billy Crystal opened the in memoriam segment honoring his best friend, Rob Reiner.

He ticked off a list of Reiner’s films, including “When Harry Met Sally,” starring Crystal and Meg Ryan, “Stand By Me,” “Say Anything” and “This is Spinal Tap,” among many others.

A photo of Reiner and his wife, Michelle Singer Reiner, appeared behind Crystal.

The Reiners were found dead in their Los Angeles home in December. Their son, Nick Reiner, has been charged in the deaths of his parents and has pleaded not guilty.

Having a slew of actors with longstanding ties to Reiner — Meg Ryan, Kiefer Sutherland, Fred Savage, Demi Moore, John Cusack, Ione Skye and many others — come on stage for the tribute was reminiscent of how the Academy did the same for director John Hughes at the Oscars 16 years ago.

Maciek Szczerbowski, who won with Lavis, said, “We just really want to thank our amazing neighborhood, and the amazingly talented community of artists that we’ve had the superb luck to work with. Thank you, the fantastic city of Montreal. Thank you, Canada.”

Yes, there was a tie and it’s not the first time this has happened at the Oscars. 

The most recent tie came during the 2013 Oscars honoring films from 2012, when “Zero Dark Thirty” and “Skyfall” tied for the sound editing category. There have been five other ties in Oscars history, making Sunday’s tie the seventh.

The first tie, which was at the 5th Academy Awards almost 100 years ago, was based on an old rule. Wallace Beery (“The Champ”) and Fredric March (“Dr. Jekyll and Mr. Hyde”) tied for best actor. They came within exactly one vote of each other, and in accordance with Academy rules at the time, they shared the recognition. That rule has since changed and only an exact match in totals would qualify as a tie today, according to the Academy.

  • “Sinners”

“I wrote this movie for my kids to say sorry for the housekeeping mess that we left in this world we’re handing off to them,” Anderson said as he accepted his Oscar.

“This is an adaptation, so I owe a huge debt of admiration and love to Thomas Pynchon. Any writer knows that…you either beg for forgiveness, or your special thanks is really to your family and the people that you share a roof with, who put up with what it means to live with a writer,” he added.

During his speech, he asked the “Sinners” cast and crew to stand up. “You’re all winners in my book,” he said. “I want to thank the Academy for thinking of our movie that came out almost a year ago. This is an incredible honor. I want to thank my fellow nominees.”

It has been another great year in filmmaking, and the only thing tighter than some of the Oscar races this year has been security for the 98th Academy Awards.

The unusually heavy security has been ramped up amid the ongoing Middle East war and concerns about retaliatory strikes by Iran. There have been no specific threats against the Oscars on Sunday, and last week, Gov. Gavin Newsom said the state has been working collaboratively with local law enforcement agencies and emergency services to ensure vital information is transmitted to keep communities safe.

The Los Angeles Police Department has set up a roughly one-mile security perimeter around the Dolby Theatre that includes uniformed officers, security cameras, K-9 units, and even surveillance drones.

For now, all is calm, and all is bright as heading into Hollywood’s biggest night.
