Everything Everywhere All At Once has enjoyed a successful start to the Oscars with Jamie Lee Curtis and Ke Huy Quan taking home major awards.

The sci-fi epic, directed by Daniel Kwan and Daniel Scheinert, went into the night with 11 nominations after sweeping top prizes at other US awards ceremonies this year.

An emotional Curtis paid tribute to all the special people in her life, shouting “we just won an Oscar”, after collecting the best supporting actress gong – her first Oscar.

The US actress, 64, said on stage: “I know it looks like I am standing up here on my own but I am not. There are hundreds of people and hundreds of people. We just won an Oscar.

“To my family, my beautiful husband, Christopher Guest, my daughters, Annie and Ruby, my sister Kelly – we just won an Oscar.

“To all of the people who have supported the genre movies that I have made for hundreds and hundreds of thousands, we just won an Oscar together.”

Looking up to the sky, the actress, who was born into Hollywood royalty through parents Janet Leigh and Tony Curtis, added: “And my mother and father were both nominated for Oscars in different categories, I just won an Oscar.”

Quan received a standing ovation as he took to the stage and hailed “the American dream” after claiming best supporting actor.

“My mom is 84-years-old and she is at home watching. Ma I just won an Oscar!” he said.

He continued: “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.

“They say stories like this only happen in the movies. I cannot believe this is happening to me – this is the American dream.

“Thank you so much to the academy for the honour of a lifetime.”

Quan has stormed this year's award season, picking up best supporting accolades at almost every major ceremony.

The first Oscar of the night, animated feature film, went to Guillermo del Toro's Pinocchio.

Taking to the stage, the Mexican filmmaker said: “Animation is cinema, animation is not a genre and animation is ready to be taken to the next step.”

Host Jimmy Kimmel kicked off the night by entering the stage attached to a parachute, in a nod to best picture nominee Top Gun: Maverick.

“Give me a second I need to adjust my danger zone. My Banshees are caught in my Inisherin right now,” he said.

“I know that being here is a dream come true for some people, thank you for inviting me.”

He also made reference to last year's slap while praising the Irish talent nominated at this year's ceremony.

“Five Irish actors are nominated tonight, which meant the odds of another fight onstage just went way up,” he said.

The remark prompted laughter from the audience and cast members of The Banshees Of Inisherin.
