Rory Kinnear will portray infamous aristocrat Lord Lucan in a new two-part ITV drama.
The series hopes to shed some new light on the circumstances surrounding the unsolved murder of his children’s nanny in 1974 and his subsequent disappearance.
Lucan, which begins filming next month in London, explores his colourful life with his friends in the exclusive Clermont gambling club, the breakdown of his marriage to wife Veronica and his battle for the custody of his children.
The series has been written by Mrs Biggs author Jeff Pope.
Rory, whose powerful thriller Southcliffe starts on Channel 4 this Sunday and who plays M’s Chief of Staff in the James Bond films, will star in the drama alongside Christopher Eccleston as John Aspinall, who ran the club, while Sir Michael Gambon also stars.
