Rebecca Rubin Film and Media Reporter Ke Huy Quan, a child star who returned to the spotlight after decades for “Everything Everywhere All at Once,” won the Oscar for best supporting actor. Earning the first standing ovation of the night, Quan took the stage and shouted out his 84-year-old mother, who is watching at home. “Mom, I just won an Oscar!” For Quan, the victory marks an especially emotional coda to awards season. He rose to fame before his teenage years, playing Harrison Ford’s sidekick in 1984’s “Indiana Jones and the Temple of Doom” and appearing in 1985’s “The Goonies.” But Quan quit acting shorty after because he found there weren’t many substantial film roles for Asian people. He didn’t return to acting until 2021 in “Everything Everywhere” as Waymond Wang, the goofy husband to Michelle Yeoh’s multiverse-straddling laundromat owner.
