Clark, hailed as a modern-day Samuel Pepys, wormed his way into the public's affection through his diaries and their withering observations of political backbiting and cabinet inertia. The six-part series was shot on Digibeta and graded by Pepper colourist Dan Coles who achieved the programme's look by using various filter techniques to give it a rich, warm and stylised grade. The director of photography was Ian Moss and the director was Jon Jones. Kate Lewis was the producer and Michael Robins the associate producer. The Alan Clark Diaries airs on BBC4 from today (Thursday 15 January).
