Awards amid wars: The glamour of Sunday’s Oscars in Los Angeles unfolded against the backdrops of wars in Ukraine and Gaza and with the U.S. presidential election on the horizon. Some at the awards show made pleas for peace, as protests calling for a cease-fire in Gaza took place outside the Dolby Theatre. In his acceptance speech for Best Actor, Murphy said: “For better or worse, we’re all living in Oppenheimer’s world. I’d like to dedicate this to the peacemakers.” While accepting the best documentary Oscar for “20 Days in Mariupol,” journalist Mstyslav Chernov noted it was the first Oscar in the history of his country, but said he wished he had never made the film. “I wish to be able to exchange this to Russia never attacking Ukraine,” he said. Words from Russian opposition leader Alexei Navalny began the in-memoriam segment. Navalny was the subject of last year’s winning documentary. In some election-year politics, Oscars host Jimmy Kimmel came onstage late in the show to read a critical social media post from former President Donald Trump. “Thank you for watching,” said Kimmel, a critic of Trump. “Isn’t it past your jail time?” Key Oscar moments >
