Close Encounters of the Third Kind (1977)

Continuity: The film starts in Muncie Indiana. There is a scene in the hills near the town. There are NO hills near Muncie, it's flat as a board.

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 *45* 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.

Other: In the climactic scene at the end of the movie when the alien mothership flies over Devil's Tower and the base, there is a shot of the mothership's shadow creeping along the ground, enveloping the shadows of the crew there. It's a dramatic shot, but since the mothership was not between the ground and the light source (the stadium lights of the base) it should not be blocking out the light, or creating a shadow.

If you have a trained eye you can see Darth Vader's ship and R2D2 from Star Wars, and several other bits of Spielberg-Lucas memorabilia.

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.

When the aliens release the humans from the mothership, we see a man walking towards it wearing a goatee and pipe. He is Dr. J Allen Hynek. He coined the term Close Encounters of the Third Kind. Hynek also worked for the Air Force debunking UFO reports.
