James Marsh has revealed that he was plagued with doubts while in the director's chair of British movie The Theory of Everything.
The Theory of Everything is one of the most celebrated films of 2015 so far, as Marsh brought the story of Stephen Hawking and his relationship with first wife Jane to the big screen.
The movie triumphed at the Baftas on Sunday night, as it scooped the Best Actor, Best Adapted Screenplay, and Best British Film gongs.
Marsh admits that this was a project where he had to keep the standards high and says he had doubts all the way through the project.
Speaking at the British Academy Film Awards (BAFTAs) at London's Royal Opera House last night (08.02.15), Marsh was asked whether he had any doubts while making the film, to which he replied: "Every day."
"You're doing something which if you don't get right all the details, the whole thing is going to fall apart. That's as much down to the cast as to what we do.
"So, you're kind of in this situation every day where you keep your standards very, very high and if you don't, then the film is just going to disintegrate around you."
Despite the doubts of the director, The Theory of Everything has been both a critical and commercial smash. Eddie Redmayne takes on the central role of Hawking, in what is a career defining performance.
He has already won the Best Actor Golden Globe, Screen Actors Guild Award and Bafta and is the favourite to now scoop the Oscar. Redmayne saw off competition from Benedict Cumberbatch, Ralph Fiennes, Michael Keaton, and Jake Gyllenhaal to win the first Bafta of his career.
The movie is also in the mix for Best Picture Oscar. Marsh already has an Oscar under his belt for documentary for Man on Wire. This is Marsh's first film since Shadow Dancer back in 2012.
