Movie identification. I vaguely remember a colonization ship with farming modules as the setting. I think it was from the 70s. Simon & Garfunkel's "The Sound of Silence" was on the soundtrack playing at the end of the movie. There was some conflict that left a single human alive on the ship by the end of the movie. I think the computer went nuts or something and killed off the other people. Not 2001, that didn't have the farming modules. Any idea what movie that was?
I downloaded and watched "silent running". It has a lot of similarities, but the entire crew dies and there is no Simon & Garfunkel. The strongest memory for the film is of a single survivor traveling off into space as a lone farmer, with The Sound of Silence playing from the story conclusion to the credits.
