Stars coming out for the Oscars
Some of the biggest names in Hollywood have already hit the red carpet ahead of tonight's Oscars ceremony.
Patricia Arquette, widely regarded as a favourite to be named best supporting actress for her role in Richard Linklater's Boyhood, posed for pictures and told reporters the epic film was the work of a man who "really wanted to honour his mom".
Other stars already out and about include America Ferrera and Anna Kendrick.
The statuettes will be handed out in the early hours of tomorrow morning - UK time - in a ceremony at The Dolby Theatre, Los Angeles, hosted by How I Met Your Mother star Neil Patrick Harris.
Eddie Redmayne's awards season success will hit even greater heights if he carries off the best actor gong for his portrayal of Professor Stephen Hawking in the hit film The Theory Of Everything.
The actor, whose mantelpiece is already laden down with a Bafta, a Golden Globe and a Screen Actor's Guild award, is favourite to win the Oscar.
He is up against another Brit - and another portrayal of a pioneering scientist - in the shape of Ben edict Cumberbatch, who was nominated for his performance as codebreaker Alan Turing in The Imitation Game.
Also in the running are Steve Carell, nominated for Foxcatcher, American Sniper's Bradley Cooper and Birdman's Michael Keaton.
Redmayne's co-star in The Theory Of Everything, Felicity Jones, and Gone Girl's Rosamund Pike are both nominated for the best actress gong.
Jones, who got her big break in Radio 4's rural soap The Archers, played Professor Hawking's first wife Jane whose memoir of life with him inspired the film.
They face competition from Reese Witherspoon, Julianne Moore and Marion Cotillard.
Keira Knightley, who stars alongside Cumberbatch in The Imitation Game, is nominated for the best supporting actress award alongside Oscars veteran Meryl Streep - who is shortlisted for a 19th time.
The other nominees are Arquette, Laura Dern and Emma Stone.
The nominees for best supporting actor are Robert Duvall, Ethan Hawke, Edward Norton, Mark Ruffalo and JK Simmons.
Both The Theory Of Everything and The Imitation Game are in contention to be named best film along with American Sniper, Birdman, Boyhood, The Grand Budapest Hotel, Selma and Whiplash.
