It was made with a very limited budget but has since achieved a cult following . The movie depicts a dystopian future, in which all plant life on Earth is extinct and only a few specimens have been preserved in greenhouse-like domes attached to a fleet of three American Airlines "Space Freighters" positioned just outside of the orbit of Mars. Lowell, a crew member aboard one of these ships, the "Valley Forge", is in constant disagreement with his other, human crewmates, who are anxious to return to a bleak and deforested yet familiar Earth. However, Lowell does have a better relationship with humanlike drones who are also aboard the ships. The science and technology depicted in Silent Running are not always plausible, and Trumbull's special effects are low quality even by the standards of the time (he had a larger budget in his later film Blade Runner), but the melancholy message is powerful. The soundtrack songs are performed by Joan Baez and the film score was composed by Peter Schickele. America Race Walking Athletes Spoiler warning: Plot or ending details follow. When orders come from Earth to jettison the domes that contain the plants, blow each of them up via nuclear explosions and return, Freeman Lowell decides it is his mission to save the plants on his ship, the "Valley Forge.
