"His world looks like nobody else's."
Best documentary - Citizenfour

Julianne Moore is the favourite to win the best actress award, but Gone Girl's Rosamund Pike may prove to be the surprise winner in front of a homegrown audience that hasn't seen Moore's film, Still Alice.
Speaking on the red carpet, Pike said: "As an actor you are trained to come to terms with disappointment."
Outstanding British film - The Theory of Everything
Fry said: "Instead of blowing kisses to camera I've decided people should kiss me" - before walking down into the audience and receiving pecks on the cheek from Ed Norton and Michael Keaton.
Boyhood is the favourite to take home the best film title.
Best supporting actor nominee Ethan Hawke told the BBC he was attracted by the film's original premise - which was shot across 12 years using the same fictional family - and its gentle subject matter.
"It felt so original to create a character using time like that," he said.
"I'm always thrilled to get to make a movie about family... to be involved in something so gentle, something that doesn't involve shooting or blowing things up."
Stephen Fry on best actor nominee Benedict Cumberbatch: "If you pass his name through an Enigma machine it translates as 'red hot public school totty'."
Kasabian have kicked off the ceremony to a packed Royal Opera House.
Host Stephen Fry is splendidly greeting everyone "on the biggest night since this night last year".
Film critic Mark Kermode told BBC News there would be "an audible intake of breath if Eddie Redmayne doesn't take the trophy home" for his role as physicist Stephen Hawking in The Theory of Everything.
Best actor contender Michael Keaton, who plays a film actor trying to recover his career on the Broadway stage in Birdman, told the BBC the role was "extraordinarily challenging".
Referring to director Alejandro Gonzalez Inarritu's direction, which is designed to look like a continuous shot, he said: "Those kind of things force you to stay focused."

BBC News has been busy on the red carpet since sundown. Entertainment correspondent Lizo Mzimba caught up with a host of major stars as they walked the red carpet, including best actress nominee Felicity Jones.
She told him she was "so proud" of her role in The Theory of Everything, which she called "a love story between two extraordinary people".
"I could just keep talking about it forever," she added.
We love the individual table decorations designed for tonight's ceremony, like this one for the team behind The Grand Budapest Hotel. It's appropriately five-star service, but where's the Eau du Panache?!
