Continuity: During the big falling debris scene, Paxton and Helen Hunt are in the red truck. The truck hits a tractor. The impact damages the windshield, and it is clearly broken, but a second later the windshield is perfect and untouched.

Continuity: During the scene when a cow blows by the truck, the truck is driving down an empty dirt road with water on both sides. During the shots of the occupants, the road behind the truck is paved, and in one of these rear shots a truck drives by in the opposite direction.

Factual error: In the begining when Jo's dad is bringing the family downstairs and say's "TV says it's big, might be an F-5" That scene was set in 1969. In reality he would not have known anything about an F-5 or any tornado with an F rating because the Fujita scale was not developed until 1971.

Deliberate "mistake": Although the film is set in Oklahoma (and north of Oklahoma City), the roads are marked by Texas road signs.

Continuity: When the solid water funnel comes and Bill, Joe, and Melissa are chasing it, if you look from when they are not up to the dirt road, surrounded by water, to when they almost get blown away, there is a red car driving by.

Visible crew/equipment: Near the beginning of the movie when Bill and Mellisa are on their way to get the divorce papers signed, you can see the reflection on the passenger side window of the helicopter and the cameraman. A few shots later when the camera angle is in front of the Dodge, you can see a brief reflection of the brake lights from the camera truck in the rear window of the Dodge.

Continuity: After Bill Paxton and Helen Hunt chase the first tornado they switch to Bill's new truck. They look at the speedometer once then they look at again about 3 seconds later and the odometer is hundreds of miles different than it was only 3 seconds before.

Continuity: In the scene where the telephone pole falls on the truck, you see Dorothy get thrown off of the bed and the tailgate gets broken off along with it. And a couple of scenes later, the tailgate is back and hanging there like it was untouched.

Continuity: When the good group is chasing the tornado, the bad group is following them (watching for skid marks on turns, etc.) anyway, the bad guys see skid marks at a turn about 10ft in front of them. They would have to turn immediately and they would still barely make the turn. The camera goes off the road and shows the driver's "what do I do??" expression for about 3 seconds, then the camera goes back on the road and the turn is the same distance away. In reality they would have passed the turn and been about 20 ft past it by then.

Continuity: When Bill and Jo are going through the house, the house is on its side horizontally. When they are crashing through the rooms though, the rooms are vertical. Also, in the same scene, you can clearly see them going up the stairs to the second floor. When they burst out, they are magically back down on the first floor. Right after that, the windshield is all cracked. A second later, it's perfectly fine.

Continuity: After the last tornado that passes directly over them, of F5 intensity, immediately afterwards, Helen Hunt still has her lightweight headphones casually draped around her neck.  A stiff breeze could have blown them off, but not an F5 tornado?

Continuity: After leaving Aunt Meg's the first time, Jo and Bill are in the red truck. Bill says, "Ok, let's get you wired." When Jo looks over at him you can see that she already has the headphones around her neck. Then they cut to Bill and when he goes to put the headphones on her neck is bare.

Visible crew/equipment: In the scene where they are trapped in the garage and the tornado is whipping through, if you look real close when the debris is falling on them you can see (very quickly) a crew member throwing trash in the background.

Plot hole: Throughout the entire movie, barns, houses, cars, 18-wheelers, etc. are demolished and lifted into the air like they were made of paper. And yet Jo and Bill pass through one tornado after another with nothing more than their hair getting messed up (a little.) You'd think just the debris flying into their faces at 100 miles an hour would be enough to give them a few injuries.

Continuity: In the scene where Jo's truck lands in the road, right after which Jonas' crew drives by, if you look quickly, you can see that the driver side (the truck was upside down) window is gone. Yet, when Jo goes to get her backpack out, she has to kick that window out. How did the window magically appear?

Continuity: In the scene where Jo's truck is lifted by the first tornado they encounter, it is dropped on the road in front of the red dodge driven by Bill's fiancée. When we see the truck drop, the drivers window is closed. As the dodge swerves to avoid hitting the other truck, the window is now opened. And finally, in the last shot where everyone is running to her aide, the window is closed again.

Continuity: They wouldn't be able to walk or run nearly so easily when near a tornado. In ametuer video footage of real tornados, the people could only move quite slowly, and were walking on an angle of 30 degrees from upright.

Visible crew/equipment: After the "sidewinder" tornado, Bill Paxton and Helen Hunt are driving through a cornfield. The cornfield merges into the main road and their truck almost runs into the evil storm chaser's van. As the car enters the road, you can see a crew member poking his head up from the corn across the road.

Continuity: In the scene at the Drive-In movie, when they all get hit by the "F4," you will notice that almost their entire fleet, including the Ford Pickup, and the Ford station wagon, are totally trashed, yet a few scenes later, after they rescue Aunt Meg, on their way to dump the sensors into the remaining Dorothys, the entire fleet is present and accounted for. By the way, where was the Dodge Ram during that entire garage sequence?

Visible crew/equipment: There's a shot late in the movie at Helen Hunt's Aunt's house - the camera shows all of her home made "wind chimes" blowing in the wind. As the camera pans in and shows a little man sawing or axing something, you see a human hand appear near the bottom of the screen as the camera leaves the scene.
