Continuity mistake: In the beginning, when Mike and Jody raise the hood on the car, Jody's hand holding on to the hood alternates between his right and left hand over three shots. (00:13:10)
Continuity mistake: As Brenda leaves the table asking "Does anyone need anything?", we see Bobby sitting by the table. When it cuts Bobby suddenly got something between his lips which weren't there before.
Continuity mistake: When Lionel's mum gets bitten at the zoo, the colour of her sleeve material changes from black/dark blue to light blue. (00:17:45)
Continuity mistake: In the scene where Jessica is in the shower crying and the power goes out, she gets out, puts on a white t-shirt and goes walking around the house. When she walks through the garage door and grabs a hammer, there is blood on the front of the t-shirt (right at or a little lower than her waist and looks like someone grabbed the shirt with a bloody hand). Where did it come from? She didn't run into anything or anyone. [There's a deleted scene showing her step on a piece of glass. She gets blood on her hands when she pulls the glass out, then presumably wipes her hands on her shirt. Still a mistake, as removing that scene means the blood appears from nowhere, but there's the reason.]
Continuity mistake: When the windows on Nick's truck are smashed, Elizabeth has protective gloves on when she covers her face from the glass, they are then gone when the truck comes to a halt.
Continuity mistake: After Nathan pours the gasoline and throws the match in the well, we see a canister and shotgun sitting by well. But when the well explodes, they've disappeared. (01:23:50)
Continuity mistake: When Jason throws Linderman to the wall he gets impaled by a sharp object stuck to the wall. However as Linderman is flying against the wall before hitting it the object isn't there. (01:13:40)
Continuity mistake: Before Bonnie's operation to remove her scars they can be seen across her back and down one arm, yet in at least two scenes before the operation she is seen wearing sleeveless or very short sleeved tops with no scars visible.
Continuity mistake: When De Niro first meets Nolte's lady-friend, they are having a conversation in a bar or restaurant. As the camera goes from De Niro to the woman, the woman's top blouse button is open in one shot, then closed, then open, etc.
Continuity mistake: When Miroslav is massaging Whitney in the hot springs, the amount of body scrub cream on them drastically changes during shots.
Continuity mistake: As Mike scrolls through the microfilm, we see his view as the pages scroll from right to left. The shot then reverses to show his face through the scrolling film, but while the film is now properly reversed, it's still moving right to left in our view. But this reversed angle should show it moving left to right. (00:12:05)
Continuity mistake: During the sheriff interview scene with Abbey, the time is listed as 3:45am, but later in the scene, the clock reads 2:15am.
Continuity mistake: When the Leprechaun is telling his slave who tried to run away that it was his 1000th birthday. The scene is set a very long time before the first film, but in the first film he tells the cop that he is 600 years old.
Continuity mistake: After Emily burns her home it's night time, then she follows the police cars and it seems like evening, and when she comes out from the water the sun shines in the background.
Continuity mistake: The guard rail disappears when the camera cuts then is back again before the bus goes off the road.
Continuity mistake: When looking at the dog from the bedroom window, there are 2 windows in the room facing the dog. When we see the window from outside only 1 window is lit up, despite both being in the same room. (00:11:30)
Continuity mistake: The mini Puft makes a hole in the marshmallow bag between the letters H and M. In further shots the hole is fixed and it's now between the A and the L.
Continuity mistake: The duct tape placed over the cut on the Janitor's left cheek is inconsistent in appearance many times. Initially, the piece of duct tape torn off the roll has a small piece missing on the lower right-hand corner that isn't there afterwards. Sometimes the lower edge of the duct tape is rippled (wavy), other times it is flush with the skin. (00:23:11 - 00:27:11)
Continuity mistake: When the main characters first decide to go diving, they are all wearing ordinary bikinis. By the end of the film, the surviving characters are wearing diving suits.
Continuity mistake: On the airplane, the shark bites off April's hand at about the wrist area, but when Fin pulls the gun in April's hand out of the dead shark, the severed limb is an entire arm up to the elbow.
