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: When the assistant coach is grabbed everyone runs to help him. In the shots from outside we can see Izzy right inside the doorway holding onto the bar, but in the shots from behind he's disappeared and there's no one holding the bar. (00:30:40)
Continuity mistake: As the assistant coach is grabbed from the bus doorway, the same reaction shot (Izzy standing up as Chelsea and Rhonda fall backwards) is played twice from different angles. (00:30:15)
Continuity mistake: When Dante finds the flare gun it's obvious that a lot of material has been cut on either side (as you can see in the DVD extras), since the flares are at the front of the bus and he isn't visible up there in any other shot during the whole exchange. (00:33:55)
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 the bus driver lights the flare she holds it in her left hand. When the Creepers grabs her it's in her right hand. (00:27:40)
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 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 the creature flies over Kimball and he looks up for it, Kimball changes from facing his left before the shot change to facing right in the closeup. (00:18:10)
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)
Continuity mistake: When the birds suddenly fly away, it startles Big K and he falls over and yells. In the next shot, all the people look up to see what happened. It then shows Big K fall over again in the next shot. (00:18:25)
Continuity mistake: When Double D takes a leak, he's standing there for a long time and you can hear the sound of urine. The Creeper flies above, and he looks up. Look at the ground, and you'll see it's completely dry. (00:18:10)
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 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)
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.
Continuity mistake: When Rhonda grabs a javelin and spears the Creeper through the head to save Bucky, he loosens his grip and they all back away. The javelin is left sticking out of the hole, jerking around for a bit, and then is suddenly lifted out of the roof. In the next shot of the Creeper on top of the bus the javelin is still in the hole, and then he lifts it out slowly.
Continuity mistake: Through most of the movie when the Creeper smiles, you can see his yellow teeth. But at the end when he is attacking Double D he has white teeth.
Continuity mistake: The first time Bucky is grabbed by the Creeper, Double D and Big K are the first two to run to help him but when the angle changes Double D and Izzy are the first two to reach him. There's no way he'd be able to overtake Big K in the two seconds it takes to run up a bus. (00:49:10)
Continuity mistake: When Minxie is beginning to having her "dream," she looks to her left because she is on the left side of the bus. But before and after this, she is on the right side of the bus. The vision occurs on the right side of the road, so she didn't change places in the dream. (00:22:00)
Answer: The car explodes a while after it crashed, too fast for Izzy to get away.
