Continuity mistake: When the Creeper rips his head off to replace it, he throws it in front of the bus, hitting the windscreen and leaving a mark. Later on, there is no mark and no head in front of the bus. (00:59:10 - 01:17:05)
Continuity mistake: When Scotty asks Minxie if the Creeper will keep on coming for the ones he has picked (right before he tries to throw the marked kids out) she starts to turn away to the left, but in the next shot she is turning to the right. (01:02:15)
Continuity mistake: When they all decide to head for the farm, as Scottie gets out of the bus, the distance between the kids changes drastically between the shots. (01:02:45)
Revealing mistake: When the kids are running through the cornfield, how can it be they cast two shadows? At night in no mans land there is only one light source, the moon (and even the moon wouldn't shine so bright). (01:06:40)
Visible crew/equipment: When the farmer fires the hole puncher cannon at the Creeper the first time with the line attached, the screen changes to a higher view, from here you can see there are two lines attached to the cannon, but he only fired one. This would be for the crew to pull the truck around safely. (01:14:45)
Continuity mistake: When Izzy, Rhonda and Double D are running away in the car, there is a shot inside the car where Izzy tells Rhonda to get out, but there is not sight of Double D in the back window. When it cuts, D is leaning against the window. (01:20:30)
Revealing mistake: When the Creeper is chasing Izzy, Rhonda and Double D in the truck at the end, during the overhead shot of Izzy pulling off the road you can see the tire tracks from previous takes. (01:22:50)
Continuity mistake: At the end, when Taggart gets off the truck after he fired into the Creeper's head, the spear he is holding changes from pointing up to pointing down. (01:29:50)
Continuity mistake: When Bucky jumps on the hood of the bus to get back in, the Creeper flies from in front of the moon towards the bus causing all the kids to run away. Bucky can still be seen staying put on the hood when they run - however in the next shot of all the kids running you see him at the front of the pack which would have not been possible given that he didn't run right away.
Factual error: In the beginning of the movie, it states that every 23rd Spring, for 23 days it eats. I am no farmer, but isn't there that saying KNEE HIGH BY FORTH OF JULY? From the looks of that corn, it looks like it is October or even November...Definately NOT SPRING in TEXAS.
Revealing mistake: When the pickup truck stops short and the Creeper goes through the cab, the truck flips over frontwards. If you look near the rear axle when it flips over you can see the puff of white smoke and the cylinder that helped to flip the truck.
Revealing mistake: When the group is running on the field, before Scotty gets his hand stabbed to the tree, there is a shot of a girl running and behind her all the others are blurred, as if its a green screen.
Continuity mistake: Just after the man says 'he looks dead to me' (he means the Creeper) he walks past the girl who holds the black guy sitting/laying on the ground. The black guy is buried deep in her arms and he holds his right arm half over his face and on her left elbow. His fellow 'pupils' walk to him. Next shot: his fellow pupils walk to him, but now his right arm is lower, exposing his face and his right hand is now at his chin instead of on her left elbow.
Continuity mistake: When Izzy finds the javelins on the bus, Bucky is the only person at the front of the bus (because he is trying to call on the radio). In the next shot Scotty appears out of nowhere at the front of the bus and yells, "Sticks. You want to hang around here so that you can poke at this thing with STICKS?" with Bucky standing right next to him.
Revealing mistake: When Izzy pushes Rhonda out of the moving truck, if you watch in slow motion you can see him pretend to open the door and then just push Rhonda down to the seat, out of sight.
Revealing mistake: When the Creeper has been harpooned, he flies in the air dragging the pick-up truck with him. The pick-up truck moves towards the back of the school bus. If you look carefully you can see that the cable attached between harpooned Creeper and pick-up truck at times hangs too loose to be able to pull the truck, so obviously the truck is moving on its own (with hidden mechanics, which you by the way can't see).
Continuity mistake: The Creeper removes Dante's top clothes after decapitating him, but in several shots of the bus overviews from the outside, the clothes are not seen anywhere.
Continuity mistake: When Betty and Coach Hanna are going through the "lock-box", she pulls out the flare gun and the Coach's arms go from being pulled in to his chest in one shot and reached out for the gun in the next.
Continuity mistake: When Farmer Taggert and his older son are chasing the Creeper as he's dragging away the younger boy, the sun is at their backs. As they watch the Creeper fly away with the son a minute later, the sun is now in front of them, having moved 180 degrees.
Continuity mistake: When Minxie sees the Creeper running on the field and throws the shuriken at the bus tire it's still daytime, but when the shuriken actually hits the bus tire it's all of a sudden nighttime.
Answer: The car explodes a while after it crashed, too fast for Izzy to get away.
