In both movies, 2001 and 2010, we see people walking in the pod hangar bay aboard the Discovery One. The only part of the ship that has artificial gravity is the centrifuge wheel, so how can people walk in the pod hangar bay?
David Bowman and Frank Poole seem to walk normally through the hangar. They don't need to steady themselves as they walk in a supposedly zero gravity environment.
(Sorry about posting a link to the entire movie. I could not find a clip of just that scene. Fast forward to 1:02:30.)
Their walking motions are very unlike the slow and cautious walking motions of the woman in this scene from the movie, 2001. Kubrick made a point of showing us her "grip shoes" so we can how she walks on a surface while in zero gravity.
In the movie, 2010, Heywood Floyd also walks normally through the octagon hallway into the hangar bay. (Fast forward to 2:37.)
We know Kubrick was a stickler for getting the details right. Was this an oversight on his part?
