The main menu music for the game has been taken directly from James Cameron's film, Aliens. If you own The Deluxe Edition CD of the movie's soundtrack, track 13 (Futile Escape) is the theme for the game's menu.
During the last quarter of the game, nearly all the sound effects for the radar equipment, assorted machines, generators, etc. are taken directly from Stanley Kubrick's classic film, 2001: A Space Odyssey. Pod Bay door effects, Pod radar beeps and alerts, and many other easily recognizable sounds are incorporated into the levels.
