During the seventies, the growing environmental concerns of the general public were beginning to appear as plot themes in both mainstream and independent film making. The science fiction genre proved the most practical medium for this with films such as Zero Population growth and Soylent Green. Cornel Wilde’s No Blade of Grass takes a different approach using an ecological disaster as the premise for a survival movie. As with Wilde’s previous movies The Naked Prey and Beach Red, the message is delivered clearly and with all the subtlety of a kick in the groin. Yet the director’s honesty carries weight as he boldly depicts how the trappings of modern civilisation are quickly stripped away in the face of impending disaster. Perhaps it was this candour that upset sections of the viewing public, who didn’t wish to confront the fragility of their own society or dwell upon their own potential for violence. Certainly the film’s distributor MGM were sufficiently bothered by what they saw, that they re-edited the movie prior to release to tone down some of the stronger content.
