President Richard Nixon - or, to give him his full title, disgraced president Richard Nixon - recorded almost all conversations he held in the Oval Office and it is these transcripts that provide the basis of the dialogue for Sky Arts' Nixon's The One.
Harry Shearer, of The Simpsons and Spinal Tap fame, takes the lead role - one he has honed over many years for the US cult comedy show Saturday Night Live - with Henry Goodman lending support as Henry Kissinger.
Nixon brags, rambles, whines and holds forth, while Kissinger fawns, flatters and, in one memorable scene, fumbles an uncomfortable and not wholly convincing explanation as to why a foreign journalist quoted him as calling his boss "a cowboy". Such is their depth of friendship that Nixon forgives Kissinger, and then orders his entire outgoing phone calls traced.
Those who prefer their viewing a little more visual might go away disappointed - the characters are largely chair-bound, it is filmed on a single set and the only discernible action is outside the window when a gardener shambles past. But for anyone wanting a fascinating, funny and slightly disturbing insight into the mind of the former leader of the free world, Nixon's The One is the one.Harry Venning, The Stage, 5th February 2014
