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.

Other: 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?
