Silent Running is a 1972 science fiction film directed by Douglas Trumbull and starring Bruce Dern, Cliff Potts, Ron Rifkin and Jesse Vint. It was made with a very limited budget but has since achieved a cult following. The science and technology depicted in Silent Running are not always plausible, but Trumbull's special effects are on par with those he created for 2001: A Space Odyssey, and the melancholy message is considered by some to be very powerful. Unusual for a science fiction film, the soundtrack contains two songs — "Silent Running" and "Rejoice in the Sun" — written by Peter Schickele and Diane Lampert and performed by Joan Baez.
