Corrected entry: When Roy starts collecting supplies to start his sculpture, he throws things through the kitchen window, breaking it. After he's done, he uses a ladder to climb through the same window, which he then slam shut behind him. It went from closed and broken to fixed and opened within a matter of frames.
Corrected entry: Throughout the shots of Roy speeding to catch up with the UFO all of his truck's exterior lights are on, but in the shot where he sideswipes the guardrail the truck's roof lights and tail lights are off. (00:24:20)
Corrected entry: In the scene where the abducted Earthlings are released from the alien mothership, the pilots of the TBF/TBM Avenger torpedo bombers all give their ranks as "captain." However, a Navy captain is equivalent to an Army/Marine Corps/Air Force colonel and the pilots are way, way too young to have attained this rank. Based on the insignia on their uniforms, they were really Navy lieutenants. (02:02:45)
Corrected entry: In the scene where Roy joins the rest of the potential travelers, they all wear jumpsuit uniforms. Each suit has an American flag displayed on the right shoulder sleeve with the stars on the left upper quadrant of the flag. By tradition, this is the way the flag is displayed on the left shoulder sleeve; on the right sleeve the stars should be in the right upper quadrant to represent the way the flag would appear if the wearer was moving forward, not retreating.
Corrected entry: Only the pilots reported in and Avenger bombers also had two enlisted men as crew members: the radio operator and the ball-turret gunner.
Corrected entry: The Richard Dreyfus character, having seen flying saucers, is haunted by this vision of a rock (Devil's Tower in North-eastern Wyoming). Then he sees it on TV and has to go there - he jumps into the family station wagon, roars out of the driveway, and we get a close up of the Indiana license plate. Next we see him in Wyoming south of Devil's Tower supposedly having driven straight through, yet he seems to have stopped off long enough to pick up Wyoming license plates.
Corrected entry: At the end of the film, when those people dressed in red leave the 'church' on their way to the spaceship, watch the blonde woman just in front of Roy Neary (Richard Dreyfuss). She is not wearing any sunglasses, but after a shot of a walking Roy you see the group walking again, and now she's wearing sunglasses, just like the rest of the group. (02:09:44)
Corrected entry: When the little boy is sleeping and he gets awakened by the strong wind, his toy monkey turns on, and then his toy record player turns on and then his remote control cars turn on. If his house was hit by an electromagnetic disturbance, wouldn't ALL of his electronic toys turn on at once, instead of one toy turning on right after another?
Corrected entry: In the desert at the landing site, I noticed that when the big alien ship comes and everyone screams and runs for cover, you can hear a bunch of women's voices shrieking and screaming. But there are no women there - except the one that came to get her little son, and SHE doesn't scream at all.
Corrected entry: When Roy and Jillian are driving to Devil's Tower, they see all the downed animals on the side of the road. In the shot where you see the cars' tires passing by the animals, you can see the ear of one of the animals move. (Technically, the animals aren't dead, they have been gassed with a heavy sleep agent. But it breaks the illusion of the animals supposed to be appearing dead). (01:25:15)
Corrected entry: In the Gobi Desert scene the camels are Dromedarys (one humped) from Arabia not Bactrian (two humped) from the Gobi Desert region.
Corrected entry: When the scientists decode the pulses broadcast by the aliens, Mr. Lacombe puts on a set of headphones and starts to play the notes on the piano in front of him. Numbers are written on the keys, ranging from 1 - 5, so he knows in which order he must play them. (00:46:35)
