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.

Some of this year's presenters at the Oscars include Matthew McConaughey, Zendaya, Dwayne Johnson, Jennifer Lawrence, "Wicked" co-stars Cynthia Erivo and Ariana Grande, and more.

Last year's quartet of Oscar winners for acting -- Michelle Yeoh, Ke Huy Quan and Jamie Lee Curtis of "Everything Everywhere All at Once" and Brendan Fraser of "The Whale" -- will also take the stage.

While walking the red carpet, the filmmakers behind "Godzilla Minus One" showed off their Godzilla-themed shoes and miniature Godzilla figurines.

Writer, director and visual effects supervisor Takashi Yamazaki, along with 3D CG director Masaki Takahashi, visual effects director Kiyoko Shibuya, and effects artist and compositor Tatsuji Nojima were all smiles as they posed for photos with the Godzilla figurines in their hands.

"Godzilla Minus One" is nominated for best visual effects tonight.

Jimmy Kimmel is hosting tonight, marking his fourth time helming the awards show.

Ahead of the show, Kimmel opened up to "Good Morning America" about why he decided to return as host.

"There were some really good movies," he said in an interview that aired March 7. "I think they're all really good. I saw them all."

"It's a big part of why I decided to host the show this year, because I do know that there are movies that people have actually seen, which makes it a lot easier to make jokes about."

The talk show host's wife, screenwriter Molly McNearney, also returns as one of the ceremony's executive producers for the second consecutive year.

Kimmel previously hosted the 89th Academy Awards in 2017, the 90th Academy Awards in 2018 and the 95th Academy Awards in 2023.
