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,"
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."
British Oscar winner Eddie Redmayne dedicated his award to all those people battling motor neurone disease (known as ALS in America), the illness which has left Professor Stephen Hawking in a wheelchair.
Redmayne paid passionate tribute to the Hawking family after he won the Best Actor award for his portrayal of the famous physicist in The Theory of Everything.

Eddie Redmayne has won the Oscar for Best Actor for his role in 'The Theory of Everything'.
Speaking backstage after the ceremony in Los Angeles, Redmayne said: "For Stephen Hawking, the illness was of little interest to him. He lives forward, passionately."
On making the movie, he said: "When I watch a film, I believe what I see on screen. We felt a responsibility to tell their story."
The 33-year-old joked that the best actor win will give him some peace of mind about his future career.
"I've always had to fight for jobs. Retaining employment will keep me very happy," he said.

The Achievement in Costume Design Oscar was Jacqueline Durran's first win, although she's been nominated twice before - in 2006 for Pride and Prejudice and in 2008 for Atonement.
Coincidentally, all three of her nominated films have been directed by Joe Wright and starred Keira Knightly.
Durran's period costumes for Anna Karenina also took home awards at last week's Costume Designer Guild Awards and the BAFTAs earlier this month.
Although the film was set in the 1870s, Durran consulted the elaborate 1950s-era couture gowns of Christian Dior and Christobal Balenciaga for inspiration, and was largely favoured by the fashion industry to take home Oscar night's top costume prize.
The North London based designer said the win was "completely overwhelming" and paid tribute to her children who were "fast asleep in England".
