The most paranoid of presidents, Richard Nixon must have been feeling unwell when he allowed three of his closest aides to shoot personal Super 8 footage of their time in the White House. Bob Haldeman, John Erlichman and Dwight Chapin — all of whom later went to prison for their involvement in the Watergate affair — together shot more than 200 rolls of film between 1969 and 1973, the highlights of which form the backbone of a new documentary Our Nixon, and show us a team of go-getting young Republicans you wouldn’t recognise from Oliver Stone’s murky biopic.
