The War Game was banned. "The effect of this film," said the BBC, "has been judged to be too horrifying for the medium of broadcasting."
The then chairman of the BBC's Board of Governors was Lord Normanbrook, who had been Secretary to the Cabinet. He wrote to his successor in the Cabinet, Sir Burke Trend: "The War Game is not designed as propaganda: it is intended as a purely factual statement and is based on careful research into official material ... but the subject is alarming, and the showing of the film on television might have a significant effect on public attitudes towards the policy of the nuclear deterrent."
In other words, the power of this documentary was such that it might alert people to the true horrors of nuclear war and cause them to question the very existence of nuclear weapons.
The Cabinet papers show that the BBC secretly colluded with the government to ban Watkins' film. The cover story was that the BBC had a responsibility to protect "the elderly living alone and people of limited mental intelligence."
Most of the press swallowed this. The ban on The War Game ended the career of Peter Watkins in British television at the age of 30. This remarkable film-maker left the BBC and Britain, and angrily launched a worldwide campaign against censorship.
Telling the truth, and dissenting from the official truth, can be hazardous for a documentary film-maker.
In 1988, Thames Television broadcast Death on the Rock, a documentary about the war in Northern Ireland. It was a risky and courageous venture. Censorship of the reporting of the so-called Irish Troubles was rife, and many of us in documentaries were actively discouraged from making films north of the border. If we tried, we were drawn into a quagmire of compliance.
The journalist Liz Curtis calculated that the BBC had banned, doctored or delayed some 50 major TV programs on Ireland. There were, of course, honorable exceptions, such as John Ware.
Roger Bolton, the producer of Death on the Rock, was another. Death on the Rock revealed that the British Government deployed SAS death squads overseas against the IRA, murdering four unarmed people in Gibraltar.
A vicious smear campaign was mounted against the film, led by the government of Margaret Thatcher and the Murdoch press, notably the Sunday Times, edited by Andrew Neil.
It was the only documentary ever subjected to an official inquiry -- and its facts were vindicated. Murdoch had to pay up for the defamation of one of the film's principal witnesses.
But that wasn't the end of it. Thames Television, one of the most innovative broadcasters in the world, was eventually stripped of its franchise in the United Kingdom.
Did the prime minister exact her revenge on ITV and the film-makers, as she had done to the miners? We don't know. What we do know is that the power of this one documentary stood by the truth and, like The War Game, marked a high point in filmed journalism.
I believe great documentaries exude an artistic heresy. They are difficult to categorize. They are not like great fiction. They are not like great feature movies. Yet, they can combine the sheer power of both.
The Battle of Chile: the fight of an unarmed people, is an epic documentary by Patricio Guzman. It is an extraordinary film: actually a trilogy of films.
When it was released in the 1970s, the New Yorker asked: "How could a team of five people, some with no previous film experience, working with one Eclair camera, one Nagra sound-recorder, and a package of black and white film, produce a work of this magnitude?"
