Silent Running/YMMV


 * Fridge Logic: The movie makes it seem like what Lowell was doing was noble, but if by this point humanity could survive without Earth's environment, was killing humans to save the domes justifiable? Possibly a case of Protagonist Centered Morality.
 * Visual Effects of Awesome: Everything from the robots to the view of Saturn and its rings. After all, the movie was directed by visual effects legend Douglas Trumbull, who had also done the effects for 2001: A Space Odyssey.
 * The Saturn effects were originally meant for 2001 but weren't ready in time, so they were used in this movie.
 * In fact, the film was made with a budget of just one million dollars, and it certainly doesn't look that way.
