Trivia: After this movie, young Cary Guffey got to play the part of an alien himself - in the Italian movies "Uno Sceriffo extraterrestre - poco extra e molto terrestre" (English title: "The Sheriff and the Satellite Kid", 1979) and its sequel "Chissà perché. capitano tutte a me" ("Everything Happens To Me", 1980); both with the Italian actor Bud Spencer.
Trivia: When the mother ship arrives at Devil's Tower, an upside down R2 D2 can be seen on the rim of the ship as it appears in front of Gillian. This is confirmed by Douglas Trumbull who did the special photographic effects.
Factual error: The aliens broadcast a series of pulses which are decoded by the scientists to be a longitude and latitude. In degrees:minutes:seconds, the longitude is 104:44:30 and the latitude is 40:36:10. These numbers are what the computer display shows and are what the scientists say (except for one slip-up in the hallway early in the scene where 104:40:30 is said). The scientists grab a globe and declare these coordinates are in Wyoming. Everybody and his brother (and the aliens) then proceed to show up at Devils Tower, Wyoming. However, Devils Tower is at around longitude 104 deg 44 min and latitude *44* deg 36min, not the *40* deg 36 min pulsed out by the aliens. If everyone had gone to 40 deg 36 min, they would have ended up in Colorado, more than a couple hundred miles south of Devils Tower, Wyoming. (00:46:23)
