Sometime in the future all the forests on Earth have been destroyed. The last forests are transported in giant greenhouses aboard space ships near the planet Saturn. Freeman Lowell, crew member of the space vessel Valley Forge, is an outsider and the only one who cares about what is left of our planet's nature. When orders reach their vessel to destroy the forests, he goes mad. He kills off the other crew members and starts a lonely odyssey...
There's something to be learnt in this movie. More than 30 years old now, it stands the test of time with its message, as mankind is still working on what possibly could end in a scenario like this. Bruce Dern may be overacting in some scenes, but his character is still much more likeable than his crew comrades. Scenery and music are beautiful, fitting well to the dark, moving and unique story. And this is the movie that made "Star Wars" possible. Director Douglas Trumbull and other SFX masters like John Dykstra and Richard Yuricich were chosen to work on "Star Wars" because of the state-of-the-arts special effects they did for "Silent Running". In 1971, they were ahead of their time. In fact, they are easily as good as today's CGI effects, but much more memorable for their time. Even the droids that help Lowell are predecessors of the ones in "Star Wars"... A must-see movie for SF fans and everybody interested in Hollywood classics.
