Downton Abbey star Hugh Bonneville is to play Roald Dahl in a biopic about the author and his wife.
The currently untitled film will focus on Dahl and his marriage to actress Patricia Neal and will show the triumphs and tragedies of their marriage in the 1960s.
British actor Bonneville, who featured in Paddington and Notting Hill, is to depict the author at a time when he was struggling to write some of his most notable children's books.
The author lived in Great Missenden with Neal when he produced classic tales such as Matilda, Charlie and the Chocolate Factory and James and the Giant Peach.
Producer Elliot Jenkins told Variety: "Personally, I can't imagine anyone better than Hugh Bonneville to give the ambivalent nature of Roald Dahl's life.
"He was such a man of wounded parts below his polished veneer of self-confidence."
The 1960s was also a successful decade for American actress Neal, who won an Oscar for Best Actress in 1963 after starring in Hud.
The superstar couple, who married in 1953, had five children, one of whom died at the age of seven, and they filed for divorce in 1983.
The untitled production has been described as a similar film as Saving Mr Banks, which depicts the story of Walt Disney convincing PL Travers to let him produce a film of Mary Poppins.
Currently, the role of Neal in the upcoming biopic has not been cast.
