Fight For You from Judas and the Black Messiah.

This news was music to the ears of US singer H.E.R, who performed the track in the preview show.

"I'm so so grateful," she said.

"I just want to say this, you know, musicians, filmmakers, I believe we have an opportunity and a responsibility to tell the truth; and to write history the way that it was and how it connects us today, and what we see going on in the world today.

"Music is power... I'm always going to fight for my people."

It's a second win for Soul, which picked up best animated film earlier in the evening.

John Batiste, Trent Reznor and Atticus Ross are the men behind the music.

Sound of Metal - Mikkel EG Nielsen.

To help explain the importance of the editing process, Hollywood star Harrison Ford read out some nonsensical edit notes from his classic film Blade Runner.

The mind boggles.

Mank - Erik Messerschmidt.

Mank is on a roll.

It's a first win, external of the night for Mank, which led the field with 10 nominations.

It's based on the true story of screenwriter Herman Mankiewicz (Mank) played by Gary Oldman, as he was working on his masterpiece for Orson Welles, Citizen Kane.

Yuh-Jung Youn - Minari.

The South Korean almost went weak at the knees after being introduced by Brad Pitt.

"Mr Pitt, finally nice to meet you," she said, drawing laughs from around the room.

"How can I win [over] Glenn Close?" she added.

The actress, who plays the wickedly kind grandmother in the heart-warming tale of a South Korean family trying to make it in America, said the cast become "a family" themselves while making the movie.

The best director-winner dropped some Chinese wisdom in her acceptance speech.

"I have always found goodness in the people I met, everywhere I went in the world," she said.

"So this is for anyone who has the faith and the courage to hold on to the goodness in themselves and to hold on to the goodness in each other, no matter how difficult is to do that.

"This is for you - you inspire me to keep going."

Before Sound of Metal won the award for best sound, its star Riz Ahmed told the US media how working on the film had "broadened my horizons and opened my mind".

He said he hopes the movie, about a drummer who is going deaf, "will do the same for audiences".

"It's a privilege to be part of project that moves you but also means something," he said.

It will mean even more if he walks away with the best actor gong later. He would be the first Muslim actor to achieve the feat.

The Londoner had to get into shape for the part, as he had to beat the skins for real.

He joked he was ahead of the game regarding the "lockdown work-out".

"I knew the pandemic was coming, I'm just gonna do the push-ups and air squats," he laughed.

Tenet - Andrew Jackson, David Lee, Andrew Lockley and Scott Fisher.

Christopher Nolan's action thriller was one of the first blockbusters of the Covid era.

Colette - Anthony Giacchino and Alice Doyard.

The film follows French Resistance member Colette Marin-Catherine as she travels to Germany, where her brother died at the hands of the Nazis.

Today is her birthday, noted filmmaker Anthony Giacchino.

"When we got nominated she reminded us that the power of documentary filmmaking ensured that her brother, Jean-Pierre was, as she put it, no longer lost in the night and fog of the Nazi concentration camp system."

Soul - "a love letter to jazz", external, the winners say. Nice.

The Disney Pixar film is about a school music teacher who dreams of being a jazz performer, with voices from the likes of Tina Fey and Jamie Foxx.

But before the teacher gets his chance of a lifetime, an accident causes his soul to be separated from his body.

"We should take a lesson from jazz musicians... wherever we are, whatever we have, we turn it into something beautiful."

And the Oscar goes to... If Anything Happens, I Love You - a film about two grieving parents.

The directors Will McCormack and Michael Govier dedicated the win to anyone who has lost a loved one to gun violence.

Distant Strangers wins.

One of the directors, Travon Free, spoke about recent police killings of black people in his acceptance speech.

"On average, the police in America everyday kill three people, which amounts to about 1,000 people a year. And those people happen to disproportionately black people," he said.

"And now James Baldwin once said, 'The most despicable thing a person can be is indifferent to other people's pain'. So I just ask that you please not be indifferent. Please don't be indifferent to our pain."

Well said.

Sound of Metal - Nicolas Becker, Jaime Baksht, Michelle Couttolenc, Carlos Cortés and Phillip Bladh.

It had to be really, didn't it? Not least because lead actor Riz Ahmed announced the winner. That could've been awkward if not.

Ahmed plays Ruben, a drummer who is going deaf. Another "character" in the film is the bold sound design which toggles between Ruben's shifting hearing and non-hearing reality, using sounds taken from his throat and elsewhere on his body.

During the filming, Ahmed had audio blockers placed in his ears and white noise pumped in for certain scenes in which his character is feeling disorientated.

Speaking to the BBC earlier this month, director Darius Marder described the "point of hearing" perspective as "undiscovered cinematic territory".

Nomadland - Chloe Zhao.

First win of the night for the bookies fave. And Zhao becomes only the second female ever to win the award.

Last year's big winner, Parasite filmmaker Bong Joon-ho, introduced this one via an interpreter from a theatre in Seoul.

We're not sure they'll be thanking him though later...

In his victory speech the Londoner said he would be back to work on Tuesday morning, but that tonight was the time "to celebrate life, man".

"We're breathing in, it's incredible," he beamed.

"Like it's incredible - my mum and my dad had sex! It's amazing."

Can't really argue with any of that, although it did seem to surprise a few onlookers... including his mum.

"I'm so happy to be alive," he added. "So I'm going to celebrate that tonight."

Goes to Ann Roth, again for Ma Rainey's Black Bottom.

Earlier on the red carpet, Daniel Kaluuya spoke to the US press before picking up the best supporting actor Oscar.

He plays Fred Hampton, chairman of the Illinois chapter of the Black Panther Party in Chicago in the late 1960s, in Judas and the Black Messiah.

"All you knew was about how he was assassinated," said the Londoner.

"Not how he lived, what he cared about, what he loved - you know? The human being."

"It's like to humanise a hero," he added.

The film is also up for best picture, and he went to great lengths to prepare for the role, he said. That included taking up opera classes and smoking cigarettes because "they change the texture of your voice".

While that may be true, we still wouldn't recommend it.
