Other mistake: Immediately after the scene where Laurie is talking to Linda while she is being strangled by Michael, Laurie looks out the window and sees the LOWER level of the other house lights turned on. Michael was on the upper level and could not have gotten down the stairs to the first level in time (1 or 2 seconds) to have turn on the lights. (01:08:20)

Factual error: Some of the scenes show trees without leaves which is correct, but several of the scenes have Myers walking through fields of crops (probably beans) in Illinois, and the trees look full, neither which could be true in late October, as the crops would be harvested or wilted by then, and the trees bare.

Factual error: Towards the end of the movie, Gibson shoots padlocks with his pistol to break them to get into a truck. Mythbusters has proven this cannot be done with ordinary weapons, or even much more powerful weapons.

Factual error: A point is made in the movie, and it is well known, that the water temperature of the ocean where the Titanic sank is near freezing, and at the end after it sinks, the people in the water only last a few minutes before going into an unconscious stupor and then dying. but on the boat, as it is taking on water while it is sinking, Jack and Rose are running around in this freezing water for what seems about 30 minutes with no apparent ill effects. The water could not have been heated substantially, and they simply could not have lasted nearly as long as they did running around in this water as the movie showed without slipping into unconsciousness.

Plot hole: During the scene where Ramus is shutting down the power in the tunnel, he shoots off a padlock with a gun with one shot. Aside from being quite dangerous at close range, both Mythbusters and Masterlock have proven this cannot be done with an ordinary gun and ammo, and certainly would be unlikely with one try. I know this used to be run-of-the-mill stuff in movies, but it does not fit modern research that has been done concerning the strength of padlocks vs using guns to open them.

Continuity mistake: At the end of the movie, right before the truck goes over the cliff, Melissa drives the cab what seems to be a couple of miles before they get to the cliff. In the meantime, Bobby, left back in the truck part, manages to get out, busted kneecap and all, and hops those 2 or so miles, showing up what seems to be a short time later to be with Melissa as she peers over the edge. I've broken my foot before, and believe me, there's no way anybody cold hop any long distance with a busted kneecap, certainly not in any reasonable length of time, it's simply impossible.

Factual error: In the laser sight scene where lasers are coming into the building from all angles, you see the entire sight line of the laser. This is impossible in real life: you will only see the point where the laser hits a solid object - there must be something substantial to reflect off of besides air. There would have to be an incredibly dense fog inside the building to see the entire laser light, and even then it would be intermittent with the changing density of the fog layer.
