These are just some of the words you can use to describe this wonderful film. Although it's now thirty years since original release it is anachronistic neither in terms of story nor special effects, and one could argue even more relevant three decades later with America's reluctance to sign the Kyoto Treaty.
For ME it has all the hallmarks of what great art SHOULD contain; a relevance to one's life and the abilty to challenge psychologically and philosophically on a number of levels. Indeed lasting eighty minutes and with only one speaking protagonist for eighty percent of it's duration, much is left implicit for the viewer to interpret. The plot of the film is simple. Cut forward to a time in the future when overpopulation and pollution of the environment has forced the last remaining forests to be moved into outer space on craft orbiting Saturn, until such time that earth is ready to replant. The craft are inhabited by four men, three of which exemplify the socially ordered and homogenous population back on earth, the other Freeman Lowell (played to perfection by Bruce Dern) being more cerebral and less bovine. After eight years they receive an order to destroy the forests and return the craft to commercial service. To save one of these forests Lowell has to murder the other three crewmembers and resign himself to a life of enforced exile without human company. Alone in space, save for two robots for company, Lowell has ample time to reflect on his actions in a way similar to Raskolnikov in "Crime and Punishment". It is also gives an insight into the psychology of isolation and alienation. The answer being for me that some HUMAN contact (even though the robots have more character and humanity than Lowell's previous crewmates), even of the lowest common denominator is necessary for mental 'health'. This is reflected in the sad ending. The DVD version of the film offers nothing more than the tape version other than a dodgy trailer for the film pre-release circa 1972 and language choice. As a footnote look out for an early example of brand/product placing! Enjoy!
