The 92nd Academy Awards ceremony is over, with Taika Waititi claiming the Best Adapted Screenplay Oscar for his Jojo Rabbit, while Parasite won a historical haul that included Best Picture.
Live updates have now finished for this article.
5:24pm: The big one! Parasite has won Best Picture in a groundbreaking upset, edging 1917, the odds-on favourite.
The Korean thriller from Bong Joon Ho also won Best Director, Best Original Screenplay and Best International Film.
It's the first time ever a film not in the English language has won the top Oscars gong. And this is after it already made history as the first Korean film to win Best International Film.
Parasite won the Cannes Film Festival’s Palme d'Or last year, among several other international awards; but it's an unprecedented delight to have it clean up at Hollywood's biggest awards ceremony.
5:12pm: Renée Zellweger wins Best Actress for Judy. She won Best Supporting Actress in 2004 for Cold Mountain.
Zellweger has already won the Golden Globe, BAFTA and Screen Actors Guild (SAG) for her role in Judy, in which she plays legendary performer Judy Garland.
5:04pm: Best Actor goes to Joaquin Phoenix for Joker.
"I don't know what I'd be without it," Phoenix says of being an actor, before making an impassioned speech about animal rights and injustice.
"Whether we're talking about gender inequality or racism or queer rights or indigenous or animal rights, we're talking about injustice."
He ended the speech on the verge of tears with a lyric written by his late brother, River Phoenix.
His speech comes a week after he used his BAFTA speech to call out white privilege.
It's Phoenix's first Oscar, but he's previously been nominated for Gladiator, Walk the Line and The Master.
4:52pm: And we're into the big four awards, and it's another unexpected delight - Best Director goes to Bong Joon Ho for Parasite.
He's emotional onstage, saying he thought he was done after winning Best International Film. He pays a really sweet tribute first to Martin Scorsese, then Quentin Tarantino, and finally the other two nominees in his category, Sam Mendes and Todd Phillips.
The win means Parasite now has a really, really good chance of taking out Best Picture - breaking records in the process and perhaps saying clearly that a new, more inclusive age of Oscars is here.
4:45pm: And Best Original Song goes to Elton John for 'I'm Gonna Love Me Again', taken from the movie Rocketman, about the pop star's life. He chokes back tears on stage beside his longtime collaborator Bernie Taupin.
It's John's second Oscar, following his win in 1995 for 'Can You Feel the Love Tonight' from The Lion King.
4:41pm: Hildur Guðnadóttir wins Best Original Score for her work on Joker. The Icelandic musician and composer has previously won acclaim for her work on HBO show Chernobyl.
4:36pm: Taika Waititi is on stage again, where he acknowledges the indigenous people of the California area where the Oscars ceremony takes place. At one point, he uses te reo Māori phrase: "mauri ora", which is often used to mean "life force".
Waititi then introduced three other presenters - Sigourney Weaver, Gal Gadot and Brie Larson.
4:25pm: Another win for Parasite, this one Best International Feature. Filmmaker Bong Joon Ho called it a "great honour", especially seeing as he was the first winner of the award with its new name - now omitting the word "foreign".
4:17pm: Bombshell wins Best Makeup and Hairstyling. The film is based on the true story of female Fox News stars taking on the network's head, Roger Ailes, and the toxic culture he presided over.
Charlize Theron played Megyn Kelly and Nicole Kidman played Gretchen Carlson in the film, each helped with highly convincing makeup and hairstyling work.
4:14pm: 1917 wins Best Visual Effects - beating New Zealand's Weta Digital, which was nominated for its work on Avengers: Endgame.
The award was presented by Rebel Wilson and James Corden, two stars of the notoriously bad Cats. "Nobody understands the importance of good visual effects," they said.
4:08pm: New Zealand's Prime Minister Jacinda Ardern has congratulated Taika Waititi for his Oscar glory during her weekly post-cabinet press conference.
She said we should all be proud of New Zealand's newest Acadamy Award winner.
"I do want to acknowledge our newest Acadamy Award winner, Taika Waititi, who has won the Oscar for Best Adapted Screenplay for Jojo Rabbit," Ardern said.
"I know we are all incredibly proud of him. I don't see many films, but I have seen that one.
"I just can't think of anyone else who could have made this film [and] played Adolf Hitler.
"I think most people thought it couldn't be done. We should all be proud of him."
3:56pm: Jojo Rabbit misses out on Best Editing - that goes to Ford v Ferrari instead.
3:51pm: Best Cinematography goes to Roger Deakins for his work on 1917 - his second win and 15th nomination. He previously won with Blade Runner 2049.
He's also been nominated for The Shawshank Redemption, Sicario, Skyfall, No Country for Old Men, Fargo, Kundun, The Reader, Unbroken, Prisoners, The Assassination of Jesse James by the Coward Robert Ford, O Brother Where Art Thou?, True Grit and The Man Who Wasn't There.
3:38pm: Ford v Ferrari wins Best Sound Editing, and 1917 wins Best Sound Mixing.
3:36pm: Just before he won! Here's a clip of when Newshub's Kate Rodger caught up with Taika Waititi just before he took off to the ceremony:
3:30pm: Eminem performs a song from 2002 film, for some reason.
3:17pm: Laura Dern wins Best Supporting Actress for Marriage Story. The Oscar trophy will join several others she's won for the role, including the Golden Globe, BAFTA and Screen Actors Guild (SAG) award.
3:10pm: American Factory wins Best Documentary, winning against stiff competition from the likes of For Sama and The Cave.
American Factory follows the opening of a factory in Ohio by a Chinese billionare, observing what happens when workers from profoundly different cultures collide.
"Working people have it harder and harder these days, and we believe that things will get better when the workers of the world unite," said director Julia Reichert during her acceptance speech.
Learning to Skateboard in a Warzone also picks up Best Documentary Short.
3pm: We're still buzzing from Taika's win! Wow! In the 15 minutes since, though, three other awards have been handed out:
Best Live Action Short: The Neighbour's Widow
Best Production Design: Once Upon a Time in Hollywood - (Jojo Rabbit was also nominated in this category and missed out)
Best Costime Design: Little Women - (Jojo Rabbit was also nominated in this category and missed out)
2:45pm: He's done it! Taika Waititi wins! He's landed Best Adapted Screenplay for Jojo Rabbit. He spoke about his mother in his speech and then, holding back tears, dedicated the award to indigenous kids around the world.
2:39pm: Oh, wow! First unexpected win of the ceremony - Bong Joon Ho and Han Jin Won have won Best Original Screenplay with Parasite.
This was not the odds-on favourite to win and means there's a greater chance of the Koran thriller landing an upset win for Best Picture, over 1917, which is the odds-on favourite.
2:23pm: To infinity, and beyond - again! Toy Story 4 wins Best Animated Film. This makes the Toy Story franchise the first to ever win two Academy Awards in the category, which has been part of the awards since 2002. Toy Story 3 also won in 2011.
Hair Love also picks up Best Animated Short.
2:15pm: The first winner of the ceremony has been announced: Brad Pitt has won Best Supporting Actor for his role in Once Upon a Time in Hollywood. And he kicked off his speech with a reference to the impeachement of Donald Trump.
"I only have 45 seconds [for this speech], which is 45 more seconds than the Senate gave John Bolton this week," Pitt said.
He's referring to the Trump-aligned Republican-controlled US Senate not allowing witnesses or new evidence in the impeachment trial, which resulted in a quick acquittal of the president.
2:05pm: Whoa! Janelle Monae kicked the show with a wildly energetic performance. The dancers were dressed as characters from Joker, 1917, Midsommar and other major 2019 films, and social media is abuzz.
Monae roamed through the audience during her performance, getting various A-list celebs to sing along with her.
1:50pm: Natalie Portman's Oscars gown is embroidered with the names of female directors many feel were snubbed in this year's Best Director category, including Lulu Wang (The Farewell), Greta Gerwig (Little Women), Lorene Scafaria (Hustlers), Marielle Heller (A Beautiful Day in the Neighborhood), Melina Matsoukas (Queen & Slim) Alma Har'el (Honey Boy), Céline Sciamma (Portrait of a Lady on Fire) and Mati Diop (Atlantics).
1:20pm: The odds-on favourite for the Best Actor winner, Joaquin Phoenix, has arrived. He ruffled feathers with his speech about white privilege at the BAFTAs last week - what will he say at the Oscars w̶h̶e̶n̶ if he wins with Joker?
1:05pm: Here he is! Taika Waititi has arrived on the red carpet. His latest film, Jojo Rabbit, is up for six awards at today's ceremony.
12:47pm: Billie Eilish walked the red carpet with two-tone green hair and "dripping" in Chanel. There were some very unimpressed reactions in the Newshub office to this outfit - but The Hollywood Reporter says she "nailed it", E Entertainment says she's "giving me everything I wanted" and The Cut called her "a whole mood".
12:30pm: The young stars of Jojo Rabbit, Roman Griffin Davis and Archie Yates, are winning hearts and loving every second of it by the looks!
12:25pm: The red carpet has been in full swing for a few hours now - here are some of our favourite posts so far:
