The first film from South Korea to be nominated in this category is now also the first to win!

It beat:

• Corpus Christi - Poland
• Honeyland - North Macedonia
• Les Miserables - France
• Pain and Glory - Spain

Bong Joon-ho applauded the recent name change to the award, which used to go under the rather more distant "best foreign language film".

"I'm ready to drink tonight," he said at the end of his speech, in perfect English! (He used a translator for the first section.)

Can he go on to cause a big upset in the main award for best picture later on tonight?

Stay tuned.

Fresh from his surprise rap performance, Mr Mathers has taken to Twitter to thank the Academy for his 2003 win for best original song.

Better late than never.

Kazu Hiro, Anne Morgan and Vivian Baker are the winners in this category.

Bombshell, which is about the 2016 sexual harassment scandal at Fox News, was heavily reliant on the hair and make-up team to make Charlize Theron and Nicole Kidman look more like the real-life news anchors they were portraying.

• Judy - Jeremy Woodhead
• Maleficent: Mistress of Evil - Paul Gooch, Arjen Tuiten & David White
• 1917 - Naomi Donne, Tristan Versluis & Rebecca Cole

The two stars of Cats are fully aware of how much help the visual effects team provided on screen in the poorly-received film adaptation of Cats.

They take to the stage dressed in full costume and make-up to match their on-screen characters as they introduce the category.

"As cast members of the motion picture Cats, nobody more than us understands the importance of good visual effects," the pair say.

Not surprisingly, there is much interest in the winners' room about the Obamas' connection with American Factory, the winner of best documentary feature.

The film is about a Chinese billionaire opening a factory in an abandoned General Motors plant in Ohio, hiring 2,000 American workers.

It explores the cultural clash between the American and Chinese employees as they try to work together to generate a profit.

Film-maker Julia Reichert said: "The Obamas took on our film at Sundance Film Festival because they felt it could help people listen to each other through stories and build relationships.

"That’s what we all do, we sit down and tell each other’s stories and it creates empathy."

She added that the name of their production company, Higher Ground, was a "beautiful sentiment".

The Harriet star will become the youngest *EGOT winner, external in history if she collects an acting award (or two) later.

Right now she's demonstrating her singing skills with Stand Up from Harriet, which she starred in.

She also wrote the song too.

What a woman. Ellen certainly enjoyed it.

*Emmy, Grammy, Oscar and Tony awards winner

• Joker - Jeff Groth
• Parasite - Yang Jinmo

Hard to argue with that one. A second win for 1917, which saw Deakins beat:

• The Irishman - Rodrigo Prieto
• Joker - Lawrence Sher
• The Lighthouse - Jarin Blaschke

• Once Upon a Time... in Hollywood - Robert Richardson.

The Brit is a bit of a legend in the movie world and won an Oscar once before for BladeRunner 2049, a couple of years ago.

He's mainly responsible for the incredible one-camera shot style of 1917.

"Thank you Sam Mendes for the most wonderful experience, we'll never forget it" he said.

This film is the first from Barack and Michelle Obama's production company Higher Ground, so it's not surprising he's tweeting about it. It won an Independent Spirit Award on Saturday as well.

The US singer-songwriter is treating the audience to a rendition of I Can't Let You, from best animated feature film-winner - Toy Story 4.

We were waiting for Eminem to return to the stage for a special Oscars bonus verse, but it was not forthcoming.

Maybe they'll discuss a collab later over a drink.

This is the first award of the night for Sir Sam Mendes's World War One epic, but it's unlikely to be the last.

The other nominees were:

• Ad Astra - Gary Rydstrom, Tom Johnson & Mark Ulano
• Ford v Ferrari - Paul Massey, David Giammarco & Steven A Morrow
• Joker - Tom Ozanich, Dean Zupancic & Tod Maitland

• Once Upon a Time... in Hollywood - Michael Minkler, Christian P Minkler & Mark

Cinema-goers in the UK will know the film better as Le Mans '66.

Donald Sylvester was out of his seat faster than a Ferrari then.

He beat:

• Joker - Alan Robert Murray
• 1917 - Oliver Tarney & Rachael Tate
• Once Upon a Time... in Hollywood - Wylie Stateman
• Star Wars: The Rise of Skywalker - Matthew Wood & David Acord

Lack of representation for people of colour at the Oscars has been a big issue this year, so Hair Love winning for best animated short is significant.

It follows the story of an African-American father who must do his daughter's hair for the first time, focusing on their relationship.

Film-makers Matthew A Cheery and Karen Rupert Toliver brought DeAndre Arnold, the teen suspended from school for having for dreadlocks, to the ceremony with them.

Cherry told the press room: "When we started this back in 2017, there wasn’t a lot of reprersentation in animation, I wanted to celebrate the joy of black hair and black families."

Toliver added: "Black hair is very close and personal to us, so freeing black hair is freeing ourselves. We want to be able to freely walk the streets - with our hair free. Now I'm in the entertainment industry where there's less policing of hair, hopefully we can make social change."

Eminem takes to the stage for a surprise performance of Lose Yourself, from his 2002 film 8 Mile.

The audience look delighted to be witnessing a performance from one of the world's biggest music stars that wasn't advertised in advance.

His rendition follows a speech from Hamilton creator Lin-Manuel Miranda about the importance of music in film.

After a string of decidedly funny speeches during awards season, such as naming his Bafta Harry because he was excited to take it back to the US, Brad Pitt's Oscars speech was something of a gear change.

He started by saying: "Our speeches here have to last 45 seconds" before adding: "That's 45 seconds more the US Senate gave John Bolton", referencing President Trump's Senate impeachment trial not seeking witnesses.

Pitt lightened up after that, saying "the view's fantastic" riding on Leonardo DiCapril's "coat tails", and made heartfelt comments about his children and parents.

But in the press room, he made no apology for taking a political stance, saying: "I was really disappointed with this week," adding: "It's a sad day and I don't think we should let it slide - I'm very serious about that."

He added that despite various reports he'd used a speechwriter for his speeches, "I definitely write them, I have some friends who help with the laughs but it's got to come from the heart".

"Historically I've always been really tentative about speeches - they make me nervous - so this round I thought I'd put some real work into it and get comfortable so I put some effort into that."

After so much recent press exposure, Pitt told the press room: "Right now I think it's time to disappear for a while and go back to making things."

She beat:

• Kathy Bates - Richard Jewell

• Scarlett Johansson - Jojo Rabbit
• Florence Pugh - Little Women
• Margot Robbie - Bombshell

Dern, who wins her first Oscar, actually played the divorce lawyer of fellow nominee Scarlett Johansson in Marriage Story - a story "about love and breaching divisions".

She gave a shout-out to her mother and fellow actress Dianne Ladd, who was actually nominated for the same award on three occasions.

Funnily enough, three proved to be more of a magic number for Dern than her mum, as she won at the third attempt.

It's a family affair.
