Everything Everywhere All at Once dominated the field at this year's Oscars, winning seven awards including Best Picture.
Michelle Yeoh won Best Actress for her role as Evelyn in the film. Ke Huy Quan won Best Supporting Actor and Jamie Lee Curtis took home her first ever Oscar for Best Supporting Actress for their roles in the film.
The film - which was nominated in seven categories - also picked up awards for Best Director, Original Screenplay, and Editing.
The sci-fi adventure film follows the story of a Chinese-American family who run a laundrette, coming to terms with their identity and family connections.
Michelle Yeoh, 60, is the first woman of Asian descent to win the Best Actress Award.
"For all the little boys and girls who look like me watching tonight, this is a beacon of hope and possibilities," she said in her acceptance speech.
"This is proof that dreams dream big, and dreams do come true."
"And ladies, don't let anyone ever tell you you're past your prime", she added.
Ke Huy Quan is only the second actor of Asian heritage to win the Best Supporting Actor prize. In an emotional speech, the 51-year-old Vietnam-born actor thanked his mother and spoke about his family's journey as former Vietnam War refugees.
"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," he said.
"They say stories like this only happen in the movies. I can’t believe this is happening to me. This is the American dream.", he added.
Jamie Lee Curtis won Best Supporting Actress for her role in the same film, which has been a big winner throughout this year's awards season.
Several English and Irish filmmakers have also picked up Academy Awards. Tom Berkeley, from Gloucester and Ross White, from Belfast, won in the Best Live Action Short Film category for their film An Irish Goodbye. The film follows the story of two estranged brothers who reunite after their mother's death.
The pair used part of their speech to get the Hollywood crowd to sing happy birthday to James Martin, who plays Lorcan in the film.
British cinematographer and London Film School graduate James Friend picked up the award for Best Cinematography for his work on First World War epic All Quiet On the Western front.
Also taking home an Oscars trophy is Mexican director Guillermo del Toro. The 58-year-old won Best Animated Feature for his Netflix film Pinocchio. It is the third Oscar he has won in his career.
Irish actors Paul Mescal and Colin Farrell were nominated for the Best Actor award for their roles in Aftersun, and The Banshees of Inisherin respectively, but lost out to Brendan Fraser who took home the prize for his lead role in The Whale.
Also among the winners were Indian composers Chandrabose and MMM Keeravaani win best song for Naatu Naatu from film RRR. It was the first song from an Indian film to be nominated.
Navalny - a film about jailed Russian opposition leader Alexei Navalny - won Best Documentary. Mr Navalny's wife Yulia Navalnaya was in attendance, and went up on stage to accept the award.
"My husband is in prison just for telling the truth", she said.
"Alexei, I’m dreaming of the day when you will be free and our country will be free.
Charlie Mackesy and Matthew Freud were two of several English and Irish winners in Hollywood. They won for their adaptation of Mackesy's book The Boy, the Mole, the Fox and the Horse.
The pair referenced the UK in their acceptance speech.
"I’ve never made a film before, so this is bewildering," Freud said.
"I know the protocol is to say thank you a lot, but I’m British, so I’m more comfortable saying sorry", he said.
Jimmy Kimmel hosted the three and a half hour ceremony, a year after Will Smith slapped comedian Chris Rock, who was presenting an award. Neither Rock nor Smith are in attendance this year.
Kimmel referenced the slap in his opening monologue.
"We want you to have fun, we want you to feel safe, and most importantly, we want me to feel safe," Kimmel said.
"So we have strict policies in place. If anyone in this theater commits an act of violence at any point in this show, you will be awarded the Oscar for Best Actor and permitted to give a 19-minute long speech", he added - referencing the fact Smith was awarded the Oscar for Best Actor shortly after the slap.
