Oscars 2019: 'Green Book' steals best picture, Colman and Malek win best actors

Road trip movie Green Book won best picture at the Oscars today, while Olivia Colman and Rami Malek nabbed best actor awards.

In an upset, Britain's Olivia Colman got the best actress Oscar for The Favourite, beating presumed front-runner Glenn Close, who starred in The Wife.

"Glenn Close - you have been my idol for so long, and this is not how I wanted it to be," a delighted but shocked Colman told her fellow actress, sitting in the audience.

Rami Malek won for his role as late frontman Freddie Mercury in 21st Century Fox musical Bohemian Rhapsody. The film won three other Academy Awards.

"I may not have been the obvious choice, but I guess it worked out," said Malek, who had been favoured to win the award.

Roma, the black-and-white Netflix film in Spanish and the indigenous Mixtec language, won two other Oscars, including foreign language film - a first for Mexico.

But it was denied what could have been the first best picture Oscar for a streaming service.

Green Book, from Universal Pictures took two other Oscars - for best original screenplay and supporting actor Mahershala Ali, who played a black pianist touring the segregated US South in the 1960s.

The Academy Awards ceremony was held without a host for the first time since 1989 and instead was filled with powerhouse music performances.

They included an emotional duet by Lady Gaga and her A Star is Born director Bradley Cooper of their original song nominee 'Shallow', which brought Gaga her first Oscar.

Queen got the Academy Awards ceremony off to a rousing start with a performance of their hit songs 'We Are the Champions' and 'We Will Rock You' that brought the A-list crowd to its feet.

Regina King won her first Oscar for her supporting role as a mother fighting for justice in If Beale Street Could Talk.
