AND that's a wrap for the 91st Academy Awards, where Green Book has caused a massive upset and taken home the big award of the night, Best Picture.

The Universal Pictures movie edged out a strong field to win the coveted golden statue, including front-runners Roma and The Favourite.

It also beat Black Panther, BlacKkKlansman, Bohemian Rhapsody, A Star Is Born and Vice.

Green Book, the story of a white chauffeur and a black musician, won three of its five Academy Award nominations this year, including Best Supporting Actor, Best Original Screenplay and of course, Best Picture.

Not everyone is happy with the result:

Another dark horse was also victorious, with Olivia Colman stormed a field of favourites including Glenn Close and Lady Gaga to win Best Actress for The Favourite.

LADY GAGA AND BRADLEY COOPER'S ELECTRIFYING PERFORMANCE

She also edged out Melissa McCarthy and Yalitza Aparicio.

The British actress, who's getting a reputation for hilarious, scene-stealing speeches, was clearly stunned.

"This is hilarious... got an Oscar!" she said. Grinning and fighting back tears.

"OK. I have to thank lots of people. If by the way I forget anybody, I will find you later and give you a massive snog. I'm really sorry if I might forget now.

"My kids who are at home and watching. Look. Well if you are not, then kind of well done. But I sort of - sort of hope you are. This is not going to happen again.

"And when I - I used to work as a cleaner and I loved that job. I did spend quite a lot of my time imagining this. Please wrap up. Right. OK.

"And thank you - my husband Ed. My best friend, I love you so much. 25 years you have been my best supporter. He's going to cry. I'm not."

Less surprising, the Best Actor award has gone to Rami Malek for Bohemian Rhapsody.

Malek beat out a talented field: Willem Dafoe, Bradley Cooper, Viggo Mortensen and Christian Bale.

"I may not have been the obvious choice, but I guess it worked out," he says of his casting in the film.

"We made a film about a gay man and immigrant, who lived his life unapologetically himself. And the fact that I'm celebrating him and this story with you tonight is proof that we are longing for stories like this. I am the son of immigrants from Egypt. I'm a first generation American and part of my story is being written right now."

HOW THE NIGHT UNFOLDED

Queen enlisted their regular touring frontman Adam Lambert to open the show with a medley honouring one of this year's most divisive films (audiences loved it, critics less so), Bohemian Rhapsody.

Comedians Tina Fey, Amy Poehler and Maya Rudolph team up to present the first award.

"Just a quick update for everybody in case you are confused. There is no host tonight, there won't be a popular movie category, and Mexico is not paying for the wall," quipped Rudolph.

"Roma is on Netflix? What next, my microwave makes a movie?" said Fey.

"Don't worry Bradley, after four kids I too have peed myself at the Grammys," said Rudolph, a Star Is Born reference which earned a big laugh from Bradley Cooper in the audience.

"Hey everyone, look under your seats, you're all getting one of those cheese sandwiches from the Fyre Festival!" joked Fey.

Seriously, can they stick around for the whole show?

Melissa McCarthy and Bryan Tyree Henry present the Costume Design award - McCarthy dressed up like a rabbit-covered Queen Anne from The Favourite.

Black Panther wins, but McCarthy and her many, many rabbits are the total scene stealers.

Singer Jennifer Hudson performed one of tonight's Best Song nominees, I'll Fight from RBG, with a big, loud performance that ends with a note that seems to go on forever (and ever). Take a listen:

Those on Twitter pointed out that Hudson's usually flawless vocals had sounded flat at times:
