Editing Silent Running (section)

==Production==
Trumbull was involved with creating effects for ''[[2001: A Space Odyssey]]'' (1968), whose director, [[Stanley Kubrick]], had wanted that film's Stargate sequence to be about [[Saturn]]; however, technical difficulties prevented completion of the sequence's special effects within the limited time available. The Saturn idea was scrapped, and Kubrick substituted [[Jupiter]] instead. Trumbull developed the sequence after production, and it was recreated for Saturn in ''Silent Running''.{{Citation needed|date=March 2012}}

The interiors were filmed aboard the decommissioned [[Korean War]] aircraft carrier [[USS Valley Forge (CV-45)|USS ''Valley Forge'' (LPH-8)]], which was docked at the [[Long Beach Naval Shipyard]] in [[Long Beach, California]]. Shortly after filming was completed, the carrier was scrapped. The forest environments were originally intended to be filmed in the [[Mitchell Park Horticultural Conservatory|Mitchell Park Domes]] in [[Milwaukee]], but the production budget forced the sequences to be shot in a newly completed aircraft hangar in [[Van Nuys, California]]. Trumbull stated in the commentary accompanying the DVD release that the geodesic domes containing the last forests of Earth's future on the ''Valley Forge'' were based on the [[Missouri Botanical Garden]]'s [[Climatron]] dome.{{Citation needed|date=March 2012}}

Three freighters are shown in the film: the ''Valley Forge'', the ''[[Berkshires|Berkshire]]'' and the ''[[Sequoia National Park|Sequoia]]''. Five other ships that carried domes—the ''[[Yellowstone National Park|Yellowstone]], [[Acadia National Park|Acadia]], [[Blue Ridge Mountains|Blue Ridge]], [[Glacier National Park (U.S.)|Glacier]],'' and ''[[Mojave Desert|Mojave]]''—are also mentioned. Each ship features a designation on the hull that notes the area from which some of its [[flora]] and [[fauna]] samples were taken. The ''Valley Forge'' is listed as "[[Bahia Honda Key|Bahia Honda]] Subtropical," indicating at least some specimens were taken from this area of the [[Florida Keys]].{{Citation needed|date=March 2012}}

The model of the ''Valley Forge'' was {{convert|25|ft}} long, and took six months to build from a combination of custom castings and the contents of approximately 800 prefabricated model-aircraft or tank kits. After filming was completed, [[American Airlines]] expressed an interest in sending the model on the tour circuit, but this was not feasible due to its fragility. (During filming, pieces of the model frequently detached.) It was subsequently dismantled after sitting for several years in Trumbull's personal storage facility. Several pieces, including the domes, wound up in the hands of collectors. Several domes survive, including one that now rests in the [[Museum of Pop Culture#Science Fiction Museum|Science Fiction Museum and Hall of Fame]] in [[Seattle, Washington|Seattle]], and another that was sold at auction in 2008.{{Citation needed|date=March 2012}}

The three drones were played by four bilateral [[Amputation|amputees]],<ref name="canby72" /> an idea inspired by [[Johnny Eck]], a sideshow performer of the early 20th century who was born without lower limbs.<ref>{{cite web |url=https://www.thehumanmarvels.com/johnny-eck-the-half-man/ |title=Johnny Eck - The Half-Man |date=August 7, 2006 |publisher=The Human Marvels – Circus Freaks and Human Oddities}}</ref> The {{convert|20|lbs|adj=on}} drone suits were custom-tailored for the actors. The suits are in Trumbull's personal collection.

The sound effects, including the drones, were created by uncredited composer [[Joseph Byrd]]. They were generated on a modified [[ARP 2600]] synthesizer with added [[Oberheim  SEM|Oberheim Synthesizer Expander Modules (SEMs)]].{{Citation needed|date=March 2012}}

Footage from the film would later be reused in [[Universal Pictures]]'s 1978's ''[[Battlestar Galactica (1978 TV series)|Battlestar Galactica]]'' and its sequel ''[[Galactica 1980]]'', notably depicting the [[Battlestarwiki:Agro ship|agro ships]]. Shots of the internal domes would also be re-used, with Dern making a fleeting cameo appearance in "[[The Magnificent Warriors]]" due to re-use of footage from the film.

===Soundtrack===
The soundtrack was written by [[Peter Schickele]], a [[bassoon]]ist who also composed comedy music under the name [[P. D. Q. Bach]].<ref>{{cite book |first=Tammy |last=Ravas |date=2004 |title=Peter Schickele: a bio-bibliography |page=7 |publisher=Greenwood Publishing Group |isbn=0-313-32070-5}}</ref> It contains two songs written by Schickele and Diane Lampert, which were performed by vocalist [[Joan Baez]]: "Silent Running" and "Rejoice in the Sun".<ref>{{cite book |last1=Nash |first1=Jay Robert |last2=Ross |first2=Stanley Ralph |last3=Connelly |first3=Robert |title=The motion picture guide |date=1987 |volume=7 |page=2920 |editor=Nash, Jay Robert |editor2=Ross, Stanley Ralph |publisher=[[Cinebook]] |isbn=0-933997-00-0}}</ref> The two songs were issued as a single by Decca (32890). An LP was released by Decca in 1972 (DL 7-9188) and later reissued by Varese Sarabande on black (STV-81072) and green (VC-81072) vinyl. In 1998, a limited-release CD by the Valley Forge Record Groupe included an additional track with the spoken introduction "God Bless These Gardens." A CD with audio restoration was released in 2016 by Intrada, Special Collection Volume 369.<ref>[https://www.amazon.com/Silent-Running-Original-Soundtrack-Schickele/dp/B01N6AGRLS Silent Running (Original Soundtrack)] Retrieved December 26, 2019 Amazon.com</ref>
