Continuity mistake: When they all walk into the liquor store in the exterior shot, there's parallel parking at the curb outside the store, but in the interior shot looking out we can see that there's perpendicular parking with steel sidewalk barriers.
Other mistake: When Baz decides to speed through the area surrounded by police cars, there's a closeup of the vehicle's rearview mirror showing the reflection of a state police patrol car that's behind them, but the problem is that Baz's vehicle does not have a rearview mirror, as seen in all the exterior shots.
Continuity mistake: After Claudia says that the tornado's coming, when they're all loading the chopper with the propane bombs there's a closeup of someone's hands lying the bombs side by side - it's a flipped shot, note the backwards writing.
Continuity mistake: When the captain of the shark finning boat climbs below deck and finds the cabin empty, the flask is lying on its side on the table, but then the flask stands itself upright.
Continuity mistake: The characteristics of Nova's large, long, raised scar change considerably from when we first see her at Fin's bar, to later in the day when Matt asks her about it while they're in the surplus warehouse, and it's not even noticeable in many shots where we can see her left thigh between her cutoff shorts and knee.
Continuity mistake: At Fin's house, Baz's watch suddenly vanishes from his left wrist when the water rushes into the house, and then it reappears when he runs from the shark and reaches the stairs.
Continuity mistake: During the school bus rescue Fin rappels down on a rope tied off on the bridge, but the method of how the rope is secured to the bridge keeps changing, and inexplicably there's a pulley with a cable leading from the bridge to somewhere off camera down below.
Continuity mistake: When they're all in the 'movie car', Baz is wearing his leather necklace and bead necklace, but when they get to the flight school the bead necklace vanishes, yet when they all walk into the surplus warehouse that bead necklace is back round his neck, and when they're outside it's gone again.
Continuity mistake: During the scene at the start, the fishing boat engaged in shark finning changes to an entirely different vessel in some shots - note the sails, helm, etc.
Continuity mistake: At the flight school, when Matt, Fin, and the others are hiding from the high winds, one of the magazine pictures is pulled off the wall beside the doorway, but when they all exit after the wind dies down that picture is back up on the wall.
Continuity mistake: After George buys it, while the others are driving to April and Claudia there's a piece of plastic stuck to one of the wiper blades as it swishes back and forth, which keeps vanishing and reappearing depending on the angle of the shot.
Continuity mistake: In the exterior shots of Fin's car, the rearview mirror's style and how it's mounted keeps changing.
Continuity mistake: When Nova and Matt are in the helicopter, the chopper's windshield, cabin, and gauge panel style keep changing.
Continuity mistake: Near the end, after Fin pushes Claudia out of harm's way, the bandage that Fin has wrapped around his left hand vanishes in closeups.
Continuity mistake: When Fin drives the vehicle to blow up the last tornado he's wearing his watch, but after he presses the nitrous button as he jumps out and lands his watch has suddenly vanished. Then when Fin runs back to his family shouting, "Get out of there," he's watch-less, but after pushing Claudia out of the way his watch is back on his wrist.
Continuity mistake: The style of the chainsaw that Fin uses at the end changes between shots, in the shot from the perspective of inside the shark's mouth - note the second black handle. (Both chainsaws can be seen on the table earlier, in the scene at the surplus warehouse).
Other mistake: During the scenes at the liquor store and in the surplus warehouse, most items on the shelves have tape covering their brand names, and even all the liquor bottles and other items have been turned around to hide their brands.
Continuity mistake: When the first girl is rescued from the school bus, as she exits the back of the bus she's wearing dark pants, but when she's being hoisted up she's wearing light stone wash jeans.
Continuity mistake: When Fin heads back up the rope to the bridge, the watch on his left wrist vanishes in his closeup, after he says, "I've had just about enough of you," and he cuts the rope to drop the shark.
