Revealing mistake: Just after Aurora finds out that Jim woke her up, she runs around the ship. When she finishes the run, she comes across a dead end and the shot cuts to Jim sitting in front of CCTV monitors. If you look carefully, her movements on the middle monitor do not match the two either side of it - a badly-synced video rather than a live CCTV feed. (01:04:00)
Revealing mistake: When the stretcher is being lowered down on the line, the high tension steel wires can be seen under the hessian rope.
Suggested correction: I don't see this as an error, because just before they lower him down, it is obvious that they have rigged a tripod and cable at a much lesser angle than straight down the face of the cliff. Once the cleanup phase started, additions like this would have been normal to remove the dead and wounded.
I am 100% certain this is an error.
The stretcher is seen lowered down hung from ropes tied at each corner, which would have really happened. Obviously this wouldn't meet safety requirements for filming, so they've "hidden" steel cables in the rope. The error is that the cables and the screw-in anchors in the stretcher are visible. Also the rope on some of the corners is visibly slack as a result.
This doesn't refer to the tripod and cable rig. Just as the stretcher starts moving, the camera shows it moving off to the left with the other soldiers watching on. One of the soldiers is holding one of the ropes that attach to the stretcher. When he lets go, it reveals that the rope is frayed, revealing the steel wire that is threaded through the rope. It's the wire that's attached to the stretcher, not the rope.
Revealing mistake: When Fujiwara is about to have sex with Hideko, there is a shot with Hideko in the foreground of the shot, kneeling on her hands and knees and Fujiwara behind her kneeling down on his knees whilst holding onto her with his left arm. Fujiwara is shown removing his trousers using only his right hand, but it is apparent that he is just miming the actions of removing his trousers before throwing them on the floor. Attempting to remove a pair of trousers with only one hand would be extremely difficult and if he is kneeling on the floor, it would require him to lower the trousers down to his knees, lift his knees off the ground, pull the trousers around the knees and then fully pull them off his lower legs. While not impossible, this would be very hard to do, but he manages to do this in just a few seconds with almost little to no struggle. (02:02:53)
