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: Dave exited the ship for an EVA to replace the 'flawed' AE35 unit. Unfortunately, Dave would've received five times the lethal dose of radiation during that brief jaunt. This is typical when in that proximity to Jupiter. Even though Dr. Floyd says "they can't be exposed to that radiation for any longer than four minutes", they'd still die from it within a few weeks of that brief exposure.Nicki
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: 2001 is the only space-based film that correctly portrays 'space' as a soundless vacuum. No whooshes, no THX explosions...
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 David Bowman is travelling through the space portal, many streaks of light can be seen passing him on both sides yet when we see David Bowman himself, the streaks are reflected in his helmet and they don't seem to be moving at all.
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: In the scene where Bowman is attempting to force entry into the Discovery by using the pod's robotic arm to manually open the exterior door, the error is that the force needed to turn the door opener in a weightless environment should have twisted the pod in the opposite direction as it wasn't physically locked to the mother ship anywhere else by the other arm.
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: 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: When they try to hide from HAL, Dave comments that there is a malfunction in the "C" pod. HAL should protest because it doesn’t detect anything wrong, but it doesn’t say anything.
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: During the trip to the Moon, the spacecraft's captain makes a friendly call on his passenger, Dr. Floyd. Although they are weightless, the captain leans onto Floyd's chair under his full body weight.
