All five songs nominated in the best original song category will be performed during the show.

In February, the Academy announced that Becky G, Ryan Gosling, Billie Eilish and more would take the stage. Becky G will perform Diane Warren's "The Fire Inside" from "Flamin' Hot," while Eilish will sing "What Was I Made For?" from "Barbie," which she co-wrote with her brother, Finneas O'Connell.

Gosling will sing the power ballad "I'm Just Ken" from "Barbie." The song was co-written and co-produced by Mark Ronson and Andrew Wyatt.

Also taking the Oscars stage are Jon Batiste, who will perform "It Never Went Away" from "American Symphony," and Scott George, who will perform "Wahzhazhe (A Song For My People)" from "Killers of the Flower Moon" with the Osage Singers.

Academy Award nominees America Ferrera, Billie Eilish and Finneas O'Connell were all smiles as they posed for photos together on the red carpet.

Ferrera, who is nominated for best supporting actress for her performance in "Barbie," stepped out in a pink gown, while Eilish wore a black blazer with a white button down shirt and a black and white skirt with a matching houndstooth purse. O'Connell wore a classic suit with a black bowtie.

Eilish and O'Connell's song "What Was I Made For?" from "Barbie" is nominated tonight for best original song.

Amid the ongoing Israel-Hamas war, "Anatomy of a Fall" actors Milo Machado-Graner and Swann Arlaud wore Palestinian flag pins on the Oscars red carpet.

The five filmmakers nominated in the best director category include Martin Scorsese, Justine Triet, Christopher Nolan, Yorgos Lanthimos and Jonathan Glazer.

Scorsese's nomination for the crime drama "Killers of the Flower Moon" is his 10th best director nomination. He won best director in 2007 for "The Departed."

Nolan, who directed and wrote "Oppenheimer," and Lanthimos, who directed "Poor Things," are up for best director at the Oscars for the second time in their careers.

Triet, who directed and co-wrote "Anatomy of a Fall," and Glazer, who directed and wrote "The Zone of Interest," are first-time Oscar nominees.

Christopher Nolan won the Oscar for best director for "Oppenheimer."

During his acceptance speech, Nolan thanked Universal Studios and the authors of the biography on which the movie is based, "American Prometheus," by Kai Bird and Martin J. Sherwin.

He also thanked all the cast members including Matt Damon, Robert Downey Jr., Emily Blunt, Florence Pugh and Cillian Murphy, as well as his wife, "the incredible Emma Thomas … producer of all our films, and all our children. I love you."

"Movies are just a little bit over 100 years old," he continued, adding, "We don't know where this incredible journey is going from here, but to know that you think that I'm a meaningful part of it, means the world to me. Thank you very much."

In addition to best director, Nolan was also nominated tonight for best adapted screenplay, which ultimately went to Cord Jefferson for "American Fiction."

This awards season, Nolan has won a Golden Globe for best director and BAFTAs for best director and best film.

Other nominees in the best director category at the 2024 Oscars included Justine Triet for "Anatomy of a Fall," Martin Scorsese for "Killers of the Flower Moon," Yorgos Lanthimos for "Poor Things" and Jonathan Glazer for "The Zone of Interest."
