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."

"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."
