Quote MessageThank you to the Academy for recognising the message of what the film says, that the most vulnerable people are treated by this government with a callous brutality that is disgraceful. It's a brutality that extends to keeping out refugee children that we promised to help, and that's a disgrace too.

The other nominees were American Honey, Denial, Fantastic Beasts and Where to Find Them, Notes on Blindness and Under the Shadow.
Image source, PAStephen Fry has got things off to a great start, appearing on stage at the end of a terrific performance by Cirque du Soleil.
He's on fine form with his opening monologue, joking that the Royal family are still recovering from finding out they were related to Danny Dyer (which was revealed in a recent episode of Who Do You Think You Are).
The Duke and Duchess of Cambridge are in attendance tonight to present a special award to Mel Brooks.
Fry joked as he looked out to the audience that he could see "row after row of the most overrated people on the planet, in their beautiful borrowed evening wear".
There was also some fine wordplay on display - Fry said: "The arrival of Arrival left us wondering if we could find a rival to rival Arrival."
Spotting Casey Affleck in the audience, Fry joked: "Affleck is without a doubt one of the finest actors in his family" - a reference to his famous brother Ben.
He also joked that British people had enjoyed watching Emily Blunt in The Girl on the Train - "Particularly commuters in southern England who have never seen a moving train."

The duchess is wearing a floral off-the-shoulder Alexander McQueen gown teamed with sparkling chandelier earrings.
The duke has been president of the academy since February 2010.
Before the first award is given out, it's important we give you a big bright red spoiler warning.

The ceremony is officially under way... stay tuned to this live page for all the latest.
The Duke and Duchess of Cambridge have arrived on the red carpet, accompanied by a flurry of flashbulbs.
They are going to be presenting a fellowship award to Mel Brooks.
Image source, PAOne of the most hotly-tipped contenders for awards glory tonight is Emma Stone - nominated for best actress for La La Land.
She told the BBC's Lizo Mzimba she doesn't know what the key to the film's success has been.
"I'm not ever really sure what parts are the most resonant, I think it's different things for different people," she said.
The moment she knew the film was special?
Quote MessageWhen we went to the Venice Film Festival , that was the first time I saw it with an audience. That was an overwhelming moment. And very hot! The director Damien Chazelle and I were sweaty and teary.
Nicole Kidman is also nominated for best supporting actress, for her role in real-life story Lion. She plays the adoptive mother of Saroo, who is looking for his birth family in India.
"I read it and I was really moved by it," she told the BBC's Lizo Mzimba. "And then I found out it was a true story and I was gob-smacked that it had actually happened."
More A-listers, including nominees Emily Blunt and Naomie Harris, are heading in to the Royal Albert Hall.

You would never know from Amy Adam's broad grin that the temperature in London was in the single figures. Then again, maybe the outfits worn by those on the other side of the barrier give it away...
Meryl Streep just whizzed up the red carpet without stopping to talk to the press. If her speech at the Golden Globes is anything to go by, maybe she's saving her thoughts for the stage...

Ken Loach, the director of I, Daniel Blake, has just arrived on the red carpet.
He told the BBC: "It's a film about people whose lives are thrown into chaos by the social security system, so it's strange to find it amongst this event of glitz and glamour."
But, he said, the movie's nomination "gives the film prominence, it gives it a profile".
"We've been very lucky with awards this year, so more people know about it, maybe more people will go and see it," he added.
Hayley Squires (below), one of the stars of the film said her reaction to finding out she was nominated was one of "shock and excitement".
Dev Patel is nominated for Lion too. He revealed he became so obsessed with wanting to star in the film that he kept knocking on the screenwriter's door, trying to get an audition.
He said of his experience shooting the film in India and Australia:
Quote MessageIt really nourished me as a human being. It took me to places in the world I had never been and I made a lifelong friend in our director Garth (Davis).
Dev Patel
Stop what you're doing right now and look at this just adorable photo of Mel Brooks.

JK Rowling tells the BBC's Lizo Mzimba she is "genuinely over the moon" about Fantastic Beasts and Where to Find Them's five nominations tonight.
"It's amazing, even if we don't win that is a huge nomination to get so i really am thrilled," she said.
Speaking about returning to the Harry Potter universe for the franchise, she said: "You know the expectation is massive, the bar is very high, the only reason to return was if you had a story you still wanted to tell, and I did have and its been incredible."
She also said she is currently in the process of casting the young Dumbledore for the next film. "He is my favourite character in the whole series. We're right in the middle of that right now," she said.
