The Hecklers (1967)

A picture of politicians under pressure, shot during the 1966 elections in Britain. The camera goes to meetings up and down the land, with an eye on angry audience excitement. The result, dramatically and cogently edited, suggests the heat, rather than the light of a campaign. It is crammed with offbeat observation and fascinating sidelights on the techniques of leading politicians in combating commotion
