Skyfall star Rory Kinnear has signed on to play enigmatic aristocrat Lord Lucan in a new British Tv drama.

The actor's two-part project will mark the 40th anniversary of the 7th Earl of Lucan's mysterious disappearance following the death of his children's nanny in 1974.

Former Doctor Who Christopher Eccleston and Sir Michael Gambon will also appear in the drama, which is based on John Pearson's book The Gamblers.

Filming will begin in London in August, according to the Bbc.
