FELICITY JONES was so good in her role as Jane Hawking, wife of world-famous physicist Stephen Hawking, in The Theory of Everything that she gave the real Jane some existential doubts.

While the film world marvelled at Eddie Redmayne's performance as Stephen Hawking - for which he scooped every acting plaudit available during awards season, culminating in the Best Actor Oscar on Thursday - Jane couldn't take her eyes off of the "astounding" Jones, joking:"I thought, 'How can I be on the screen and in a cinema seat at the same time?'"

Jones has previously paid tribute to the Hawking family's generosity in sharing their memories and time with the actors, helping her and Redmayne to achieve such believable and moving performances.

"My instinct was when you're playing a real person you want to get that person's blessing and that's just building up trust with each other," Jones told The Independent."Jane is incredibly open, she showed me photos of her and Stephen when they first met and I really felt I was getting this glimpse into an intimate side of their lives."

Jones lost out on the Best Actress Oscar to Julianne Moore, who - like Redmayne - scooped every acting award in the category this year.
