Jamie Lee Curtis won the Oscar for best supporting actress for her performance in "Everything Everywhere All at Once."

Curtis also shouted out her famous parents Tony Curtis and Janet Leigh in her victory remarks, saying, "My mother and my father were both nominated for Oscars in different categories -- I just won an Oscar."

Ke Huy Quan won the Oscar for best supporting actor on Sunday night for his performance in "Everything Everywhere All at Once."

Quan began his acceptance speech by sending a message to his 84-year-old mother, who he said was watching from home. "Mom, I just won an Oscar!" he said.

"My journey started on a boat, I spent a year in a refugee camp and, somehow, I ended up here on Hollywood's biggest stage," Quan continued. "They say stories like this only happen in the movies. I cannot believe it's happening to me. This... this is the American dream."

Quan also gave a shout-out to his wife Echo, who he said told him his time would come one day.

"Dreams are something you have to believe in," he said. "I almost gave up on mine. To all of you out there, please keep your dreams alive."

Other actors nominated in the category included Brendan Gleeson for "The Banshees of Inisherin," Brian Tyree Henry for "Causeway," Judd Hirsch for "The Fabelmans" and Barry Keoghan for "The Banshees of Inisherin."

Scheinert dedicated his win to his public school teachers in his acceptance speech, saying, "You guys educated me, you inspired me and you taught me to be less of a butthead."

Kwan, meanwhile, paid tribute to his mother, whom he credited for protecting his "inner storyteller." He also honored his wife, whom he said had protected him "from the most negative thoughts, especially when I'm writing."

Other nominees in the category included Martin McDonagh for "The Banshees of Inisherin," Tony Kushner and Steven Spielberg for "The Fabelmans," Todd Field for "Tár" and Ruben Östlund for "Triangle of Sadness."
