The Best Picture award went to "Green Book" — civil rights dramedy about a celebrated black pianist who befriends his white driver as they tour the segregated American South in the 1960s which also won the Oscar for original screenplay earlier this evening.
The grand reveal of this ceremony was Alfonso Cuaron's "Roma" taking home three Oscars. Cuaron took the award for Best Director — the second time he has won an Oscar for directing since 2013's "Gravity".
"Roma," the black-and-white ode to Cuaron's childhood in Mexico City, also won the Oscar for best foreign language film — a first for Mexico — and Cuaron was also named best cinematographer.
"BlacKkKlansman" — another best picture nominee, was the winner of the Academy Award for best-adapted-screenplay.
The best actress went to Olivia Colman for her role in Yorgos Lanthimos' "The Favourite", where she portrayed Britain's 18th-century Queen Anne as an insecure, frail and tempestuous royal who treats her horde of indoor rabbits as if they were her dead children. This was the first Oscar and first nomination for the actress who is little-known internationally but very well-known in Britain.
Mahershala Ali was named best supporting actor for playing a black pianist touring the segregated US South in the 1960s, marking his second Academy Award in three years.
Regina King won her first Oscar for her supporting role as a mother fighting for justice in "If Beale Street Could Talk".
Ryan Coogler's big budget superhero movie "Black Panther" took several early awards: best original score, best production design, and best costume design.
The title of the best-animated film went to another superhero blockbuster, produced by Sony and Marvel — Spider-Man: Into the Spider-Verse, reflecting the huge impact of superhero movies, while the best short animated film award went to "Bao".
The hostless show opened up with a grand performance by the British band Queen, who kicked off with their signature songs "We Are the Champions" and "We Will Rock You", with singer Adam Lambert replacing the group's deceased frontman, Freddie Mercury. This is the first time in Oscars' history the ceremony was opened by a rock band.
Best documentary feature went to "Free Solo", short documentary — to "Period. End of Sentence".
The award for best visual effects was taken by "First Man", directed by 2017 best director Damien Chazelle.
The best make-up and hairstyling award went to best picture nominee "Vice".
The lack of a host did not deter presenters from cracking Hollywood and political jokes. Maya Rudolph, who appeared in the beginning of the ceremony with Amy Poehler and Tina Fey referenced US President Donald Trump's campaign to build a wall on the US' southern border. The trio ran through the kind of jokes, they said, they would have said in the Dolby Theatre if they were, in fact, hosting, saying "We are not your hosts. So just a quick update in case you're confused. There is no host tonight, there will be no popular movie category and Mexico is not paying for the wall".
