Silent Running

Everything About Fiction You Never Wanted to Know.
Running Silent in my sleep

Silent Running is an environmentally-themed Science Fiction Movie from 1972 directed by Douglas Trumbull and starring Bruce Dern.

In the future, the environment of Earth has been destroyed, with the only plant and animal life left being preserved in domed forests aboard American Airlines space freighters in orbit around Saturn. Freeman Lowell, a botanist and apparently the only remaining environmentalist in the world, tends to the forests religiously and hopes that they can one day be returned to Earth and used to restore it to its natural state. When the decision to reassign the freighters and destroy the domes is made, Freeman becomes obsessed with protecting them. He kills his crewmates and escapes with the last dome, assisted by three robot drones he names Huey, Dewey, and Louie. He must then escape discovery and survive a collision with Saturn's rings.

Not to be confused with the song of the same name by Mike and the Mechanics.
