Eddie Redmayne wins Oscar as Birdman named Best Picture

Oscar winning actress Julianne Moore has been praised for helping to "confront the stigma and isolation" felt by Alzheimer's sufferers, in her award acceptance speech.

Ian Kremer, executive director of the American organisation Leaders Engaged on Alzheimer's Disease, thanked the actress on Twitter saying: "Thanks to @_juliannemoore for confronting #stigma & #isolation of #Alzheimers/#dementia in #StillAlice speech."

Moore, who won the Best Actress prize for her role as a professor who develops a rare form of Alzheimer's at the age of 50 in the film Still Alice, accepted her Oscar by paying tribute to those who suffer from the illness and highlighting the fact that "so many people with this disease feel isolated and marginalised."

The British Alzheimer's Society also posted their congratulations to the star for her role on Twitter:

Stephen Hawking has said he is "very proud" of British actor Eddie Redmayne after his Oscar win.

Redmayne scooped the Best Actor award for his portrayal of Hawking in the film The Theory of Everything which tells the story of the physicist in his younger years.

Hawking congratulated Redmayne by posting a message to the actor on his official Facebook page:

On the red carpet Eddie Redmayne told ITV News he is still struggling to come to terms with his Oscar win, saying: "I don't think I've managed to make any sense of it just yet,"

Actor Jared Leto was back to his photobombing ways at the Oscars, this time striking a wacky pose behind Birdman producer James W. Skotchpole.

While it was a good effort, it did not beat Leto's efforts at last year's Vanity Fair Oscars party when he photobombed every single one of actress Anne Hathaway's pictures.

Eddie Redmayne has paid tribute to everyone who worked with him on The Theory Of Everything, for which he won his Oscar and expressed his disbelief that he won the coveted award.

He told Good Morning Britain: "Can you believe it?...It's this extraordinary thing when you're lucky enough to tell a story like this. The amount of people involved that help make you be able to tell that story is extraordinary."
