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 a contractor fires a grenade at an enemy technical, the truck visibly explodes and moves upwards before the (most likely) CGI projectile hits it. (01:02:00)
Revealing mistake: When the hiker's body is taken out of the cottage, it is so obviously a dummy - you can see the join in the neck.
Revealing mistake: When the ladies are being escorted by the police to NASA, their Chevy is in park.
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 Jerico is having his surgery the angle of the device that will be transmitting the memories is inconsistently angled in the real shot versus the monitor image.
Revealing mistake: Some scenes in the jungle involve heavy downpours of rain, but rain drops are not seen splashing on Mowgli or the jungle creatures.
Revealing mistake: Towards the end of the movie, the principal puts on his hat which turns his hair green. But you can see the green paint has already been applied before he puts his hat on.
Revealing mistake: The "snow" is obviously fake and it is largely absent on the left third of the screen and, to a lesser extent, the right side. Although it apparently recently started snowing, the snow was not melting when it hit the pavement, which would mean it was cold enough for snow to also "stick" onto metal vehicles (but did not) and the car pulling into the alley should have left tire tracks. At various spots throughout the movie, "snowfall" is spotty and irregular. (00:26:48)
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)
Revealing mistake: When Lockhart slices his cast open, his missing tooth is just cosmetically blackened. (01:47:00)
Revealing mistake: Right after the little girl sprays the monster with bug spray, you can see the costume of the monster, it's wearing a black cap. (01:19:00)
Revealing mistake: Set in Pittsburgh, PA, scenes were obviously filmed out of sequence. Many scenes were "out of sync" with the snowfall, whether in progress or amount (if any) already accumulated. For example, there was no snow downtown, but views from the helicopter showed snow-cover around the nearby parkway (Route 376). In another scene, it was snowing when Ryan turned his Jeep into a downtown road that was covered with at least one inch of snow; switching to a "live" newscast, the sun was shining outside.
