Other mistake: In addition to the brake lights, there are no lights at all on the back of the car when you see it driven from behind. However, you can see that the lights are on from the front of the car.
Other mistake: Jason seems to be able to teleport in this film. Most notably towards the end when Mr. McCulloch is running from him down an ally, Jason is behind him, then in a matter of seconds he's on the top floor of a building, without ever entering it, in time to throw McCulloch out the window.brianjr0412
Other mistake: In the beginning of the scene where Gage is killed by the Orinco truck, the truck leaves the plant. The number on the trailer is marked T-80. In the scene, the truck rolls over in the accident. In later scenes where Rachel hitches a ride home with another Orinco truck, the number on the trailer is also marked T-80.
Other mistake: When Nicole is getting attacked near the of the movie, they are seen struggling in silhouette behind a sail. You can see they are facing off to the left of the camera shot. When Ben shoots an emergency flare at Ben through the sail, it somehow ends up in his mouth. Also the sail should have stopped the flare then caught on fire. In the movie it puts a perfect burn hole in the sail and no fire.
