"Poor Things" won the Oscar for best costume design.

After doing a bit with Jimmy Kimmel about the Oscars streaker at the 46th Oscars in 1974, John Cena presented the award to "Poor Things" costume designer Holly Waddington.

"Thank you to the academy, thank you to my fellow nominees," Waddington began. "It's an amazing privilege to be in the same room as you all. You're the people who inspired me to be a costume designer in the first place."

"'Poor Things' was a very rare opportunity to be really free and artistic in a creative process as a costume designer," she continued. "Thank you, Yorgos [Lanthimos], for that and for making such bold and brave work."

Other nominees in the category included "Barbie," "Killers of the Flower Moon," "Napoleon," "Oppenheimer."

Billie Eilish and her brother Finneas O’Connell delivered a moving performance of their Oscar-nominated song “What Was I Made For?” from “Barbie.”

Eilish sang while O’Connell accompanied her on the piano. The duo received a standing ovation from the audience after their performance.

“What Was I Made For?” may earn Eilish and O’Connell their second Oscar tonight. They previously won the Oscar for best original song in 2022 for “No Time To Die” from the James Bond film of the same name.

"20 Days in Mariupol" won the Oscar for best documentary feature film.

Filmmakers Mstyslav Chernov, Michelle Mizner and Raney Aronson-Rath accepted the award, which was presented by Kate McKinnon and America Ferrera.

"Probably I will be the first director on this stage who will say I wish I had never made this film," Chernov said about his film, which offers a harrowing account of the Russia-Ukraine war. "I wish to be able to exchange this [for] Russia never attacking Ukraine, never occupying our cities. I wish to give all the recognition to Russia for killing tens of thousands of my fellow Ukrainians."

"I wish for them to release all the hostages, all the soldiers who are protecting their lands, all the civilians who are now in their jails, but I cannot change the history," he continued. "I cannot change the past. But we, all together, you ... some of the most talented people in the world, we can make sure that the history record is set straight, and that the truth will prevail -- and that the people of Mariupol and those who have given their lives will never be forgotten. Because cinema forms memories and memories form history."

Other nominees in the category included "Bobi Wine: The People's President," "The Eternal Memory," "Four Daughters" and "To Kill a Tiger."
