SILENT RUNNING opens. Directed by Douglas Trumbull, from a screenplay by Deric Washburn, Michael Cimino and Steven Bochco. In a huge bio-dome aboard one of 3 cargo vessels plying deep space, astronaut/botanist Bruce Dern obsessively tends to what is left of a post-apocalyptic Earth's trees & vegetation. Dated, still fascinating ecological sci-fi parable. With Cliff Potts, Ron Rifkin and Jesse Vint.
