Factual error: When trees fall over from storms, they pull out a large amount of roots and pull up a large circular dirt base from the ground. The trees that fell over after the storm in this movie only had a few roots and no ground pulled up.

Continuity: When the tentacle monster rips out a chunk of Norm's chest, a large spray of blood splashes on his right-side jaw and cheek. In every subsequent shot of him, this blood is gone and his jaws are completely clean. Submitted by Twotall

Continuity: When Norm is pulled out through the loading door, he is first pulled all the way out. (He sits up, bangs his head, falls straight back down and is pulled another meter or so.) In the next shot, which shows him from above, his entire upper body is still inside the door, before he is pulled through again. Submitted by Twotall

Factual error: There is a scene near the beginning of the movie when the mist has just begun. A firetruck roars by, and has Caddo Parish Fire Dept. on the side. This movie is set in Maine. Louisiana is the only state with parishes. All others, including Maine, have counties.
