Other mistake: The bear is lit by a flashlight before Cole actually picks the flashlight up.
Other mistake: When Ivan Ooze gives out those slimes to the kids, that boy is at the very back of that big crowd. As Ivan Ooze starts giving them out, it switches to the boy and he already has some slime, but it would have taken a few minutes for him to get one. (00:42:00)
Other mistake: The plot of this film can't seem to make up its mind whether or not the Cedar Creek virus is airborne or not. Several scenes show characters walking around in infected areas with and without protection in the same area. At one point Casey's suit breaks implying that he immediately contracts the virus within mere seconds without even having breathed it in yet we see other people walking around with either their face or eyes unprotected.
Other mistake: In the scene where they are 1st landing at Bangor it is known that there is no electricity at the airport. If you look closely during the landing you will see that the runway lights are on. (00:50:40)
Other mistake: In the beginning of the film when you're introduced to the younger, humanoid Sil in the laboratory, an extreme close-up of her eyes and face clearly reveals the young actor's contact lenses.
Other mistake: After the scene shifts from Rico busting out of the black body bag to the street scene, as the camera pans down and to the left, water running off the shading panels of the camera moves along with it.
Other mistake: When in the jungle, Elliot says to Amy "Let's turn your volume down" and makes an adjustment to Amy's backpack voice synthesizer. A few seconds later Amy "speaks" at exactly the same volume as before.
Other mistake: The first time Rebecca gets Keslee's arm stuck, he wipes his head with his hand, but she goes to punch him, her hand passes through the hologram. His hand should have gone through as well. Also, when she shoots the bucket at the end, it dumps water on him, and he coughs, though the water shouldn't have bothered him.
Other mistake: At the club, Sid likes the blue suit and takes it. But he is still wearing the suit he came in when Denzel's character shows up and is not carrying the blue suit as he leaves. If he somehow had it concealed on him it would have been shot up when he was thoroughly shoot. Yet when we next see Sid he is wearing the blue suit and there is not a mark on it.
Other mistake: When Durant and his men chase Lauri out on the streets, they are waving around their guns and causing great commotion and panic amongst bystanders. However, in certain wide shots, you can see some of the extras are standing still, and not reacting to the chaos as they were in previous shots.
