Now here's a drama that's causing a fair bit of bother off screen too... Written by Jeff Pope, it's based on the life of flamboyant aristocrat Lord Lucan. In 1974, with escalating gambling debts and his marriage collapsing, Lucan becomes obsessed with regaining custody of his children. On one fateful night in November that year, the youngsters' nanny Sandra Rivett is bludgeoned to death in the basement of the family home in London's Belgravia district - and the earl is never seen again. Rory Kinnear, Christopher Eccleston, Catherine McCormack, Michael Gambon, Paul Freeman, Rupert Evans, Gemma Jones and Leanne Best make for an impressive cast, eh?
