Ralph Fiennes has admitted he felt a lot of responsibility to get his portrayal of Charles Dickens right in The Invisible Woman.
The Skyfall actor plays the famous writer in an adaptation of Claire Tomalin's book about his romance with a younger woman, Nelly.
Ralph told Vulture: "I felt a responsibility to get Dickens right - that was the biggest thing. I didn't want him to be easily judged in this.
"I guess what's most intimidating to an actor is if there's someone else who's played the part before and been hugely successful. If someone has made their mark and defined a role and later on you take it on, you're under the shadow.
"I can't find a film where Dickens has been portrayed at all - on some British TV things, I think, but I've not seen them. That cuts you a bit of slack. You haven't got that in your head. But there are massive scholars and people who know Dickens inside out."
Ralph said that his co-star Felicity Jones, who played Nelly, also wanted to make sure audiences saw the true nature of their relationship.
He explained: "I felt a responsibility to Dickens, and to Nelly. Felicity [did] also. We felt a responsibility to the complicated nature of the relationship - the funny little compromises and shifts, coming, going, Nelly retreating from Dickens and then falling for him. All those things that happen, I think, in relationships, in evolving relationships."
The Invisible Woman is due to be released in cinemas on February 7.
