Michelle Yeoh has become the first Asian star to win the Oscar for best lead actress for her role in the movie, "Everything Everywhere All at Once."
Yeoh, who was born in Malaysia, received the prize at the 95th Academy Awards ceremony in Hollywood in the US state of California on Sunday.
She said, "This is a beacon of hope and possibilities," and "dreams do come true."
Ke Huy Quan, born in Vietnam, won this year's Oscar for best supporting actor for his role in the same movie.
As a boy, he starred in a 1984 "Indiana Jones" movie and "The Goonies" in 1985.
The actor said, "My journey started on a boat. I spent a year in a refugee camp. Somehow I ended up here on Hollywood's biggest stage."
He went on to say, "They say stories like this only happen in the movies. I cannot believe it's happening to me. This is the American dream." He called on people not to give up their dreams.
"Everything Everywhere All at Once" won in a total of seven categories, including best picture and directing.
The Oscar for best documentary feature film went to "Navalny." The film portrays Russian opposition leader Alexei Navalny -- a leading critic of President Vladimir Putin.
