Corrected entry: During the scene when the photographer is taking photographs of the scientists next to the monolith on the moon, a flying insect e.g. a fly or moth, can quite be briefly seen against the dark background of the monolith itself.
Corrected entry: In the scenes with the lunar shuttle and the lunar buggy, we see a swirling cloud of dust as they are touching down. The dust would only swirl around like this within an atmosphere; it would not do this on the airless moon. (00:40:00 - 00:50:40)
Corrected entry: The initial scene shows a desert with Brazilian tapirs grazing in the background. Tapirs have never been recorded living in any sort of desert, either through live sightings, secondary evidence, or fossil record.
Corrected entry: In the montage of various Earth orbiting satellites, there is a shot of a device which is clearly illuminated mainly from underneath, whereas the Earth & Moon in the background are clearly lit from above.
Corrected entry: When Heywood Floyd was talking to his daughter on the video-phone, the camera at home was moving slightly (up, down and sideways) to follow the movements of the girl. In reality, the phone camera would have been in a fixed position.
Corrected entry: In the scene where Dave is replacing the AE35 unit at the antenna he is steadying himself only with his hand as he does his work. In reality every motion he made would have a equal opposite reactions so he would have been twisting in space and unable to do a basic task. He should be more firmly anchored to the antenna to be accurate.
Corrected entry: When the scientists are on the moon and approaching the monolith, the lighting from the floodlights changes from shot to shot.
Corrected entry: When Floyd is going to make his call to his home, the image of the Earth or the Moon seen in the window behind him changes the way it circles from clockwise to anticlockwise.
Corrected entry: The stewardess, in her 360-degree stroll to the control room aboard the spherical Aries lunar shuttle, is most certainly going through the wrong door, if you think about where the control room is relative to the rest of the interior (she should have been stepping through the access on the top of the set).
Corrected entry: As the Pan-Am shuttle is approaching the spinning space station there as a shot of it from within the hub based dock. The star filled background is spinning as it ought to, but the shuttle, which is not yet centered on the dock, is seen swinging across the sky independent of the background. To do this the craft would be tracing a spiral through space.
Corrected entry: In the zero-G sequence of the shuttle approaching the moon Dr. Floyd is served a meal in a zero-G tray with straws. While Dr. Floyd sips through the straws to eat from the zero-G food tray, the food puree falls back down the straws into the tray wells (leaving them "clear") after he finishes sipping, an effect of gravity. In zero-G, the food puree should remain visible in the straw, and not fall.
Corrected entry: How could there be dust clouds when the lunar probes land when there is such a thin atmosphere on the moon? It happens twice when Dr. Floyd is going to check out the monolith.
Corrected entry: When troubleshooting the AE-35 unit in the pod bay, the unit is resting on a console, unsecured. The unit should float, since the pod bay doesn't possess artificial gravity, only the main living space does.
Corrected entry: Poole takes a pod out to replace AE35. We see this pod spinning off into space. Bowman takes pod 2 out to retrieve Poole. He eventually blows the door to get back inside Discovery. There is no indication that he bothers retrieving this pod: He is occupied with HAL. Bowman takes pod 3 to check out Stargate. He and the pod are sucked in. So where did pod 4 come from in the movie 2010?
Corrected entry: In the scene where Dave is going into the room to shut down HAL, he is wearing his space suit and his sleeve becomes unattached from his glove when he is opening the door. This would be lethal, given that HAL messed up the pressure and drained the oxygen.
Corrected entry: There is a scene where one of the astronauts is drinking out of a juice box in space (zero gravity). When he is done drinking from the straw the juice falls back down the straw as if there was gravity.
Corrected entry: When the ship's computer and one of the crew members are playing chess, the computer stated a mate in 2, which is not true. It's mate in 3.
Corrected entry: The spacecraft Discovery has a rotating centrifuge-room that the astronauts use to avoid the detrimental effects of prolonged weightlessness. We see the rotation when Dave first enters the room and again later when he and Frank re-enter the room after inspecting the AE-35 Unit. But by Newton's laws the torque on the centrifuge must be countered by an equal anti-torque, so the surrounding body of the ship ought to be counter-rotating to conserve angular momentum.
Corrected entry: While Dave Bowman & Frank Poole are in the pod bay they lean against the workbench much as anyone would on Earth, yet the pod bay is a weightless environment.
