Revealing mistake: When Bill and Jo are driving towards the first tornado together (arguing), it's clear there's no windshield in the red truck. There's no rear view mirror and it's perfectly clear. During the next few scenes, a rear view mirror appears and there is mud on the windshield around the wiper tracks.Ben's Mom
Visible crew/equipment: When Bill's fiance is driving over after the first tornado, when the truck lands, she swerves and she stops. As she is getting out, a camera is visible. When the camera backs up though, a crew-member pulling it back is visible in the door.
Factual error: We all know that when any tornado is on the ground and/or near moving towards us, things get blown around, like trees, grass, and other things. There are two things that I found that didn't look right. It's in the scene when the F-5 tornado is chasing Bill and Joe to the Barn. First the grass and cornfield are moving but not the trees. And second, when the tornado blows away the brown picket fence we see most of the pickets shoot upwards, which is impossible because they are nailed to horizontal boards. It would either take a far stronger wind than they're currently in to rip the pickets straight up, or the pickets were made out of far cheaper wood than they appear to be.Movie Lover
Continuity mistake: When Bill is walking over to see Jo for the first time, he passes Joey working on the hood of a truck that was previously shown in front of the blue Doppler van and next to the green tractor. Throughout this sequence, this taupe/brown pickup with camper flops back and forth between the two places. Lawrence finally drives it off.Sheri Hartman
Continuity mistake: In the first few seconds of the movie, there's a landscape shot of a fence. Right in front of the fence there's a little piece of grass blowing in the wind, and it's just so obvious that they looped the 1 second to make it last 5 seconds, because the grass keeps jumping back and forth. Minor but annoying.
Continuity mistake: After the pitstop, when Jo's team and Jonas's team have the encounter, Jo's team takes off to chase another tornado. When we hear Dusty holler, "Hey you guys, woohoo," we see Jo reach for the CB and dial from channel 22 to 18. But when Bill says, "Shi_," Jo reaches down to adjust the CB and the channel showing is 39.Sheri Hartman
Continuity mistake: At the beginning, when the guy comes back to have Jo sign the divorce papers, He says "you missed one", and you can clearly see a red tab on the paper that she missed. In the next seen it's gone and in the next it's back again.
Other mistake: When the twister hits the drive in theater, the sirens are wailing, but nobody reacts. Only when Jo screams at the waitresses they start panicking and run. The movie is set in Oklahoma, smack in the middle of tornado alley. The people there know what the sirens mean, they sure don't need no out-of-town big-shots to tell them to get under cover.Doc
Continuity mistake: When Bill is going over the divorce papers, he comes to the page missing Jo's signature. It only has one red arrow near top right. When he hands it to Jo, she starts looking at it, then flips up page to look at others, and the missing signature page is a completely different page with two red arrows, one toward the top and another, on the right, toward the bottom.

Audio problem: When the two storm chasing crews have stopped at the Hot Pit Bar-B-Q, in the shot where Bill runs over to beat up Jonas for supposedly stealing his design for Dorothy, Jonas's mouth is not moving and yet we hear him continuing to talk about DOT 3. (00:19:45)
Continuity mistake: When the red truck is driving to the tornado where the sensors spill, the scenery and pavement change between shots. First, they are driving down a road with trees on both sides. Then, they are driving down a large empty area where you can see the the horizon. Finally, they drive into a valley with forests on both sides. And this happens in a matter of seconds.
Factual error: With the last Dorothy, Bill and Jo burst open the door of the Dodge and make a run into the cornfield. This is not possible. Corn stalks are strong and would hold the doors back, no matter how hard they pushed. Bill Paxton and Helen Hunt were unable to open the doors during the scene, so it required them to open the doors before they entered the cornfield in order to jump. They filmed the scene of them driving through the cornfield and start opening the doors. Then they cut and restarted filming, this time with the doors already open so they can jump. Then careful editing was used to merge the scenes together to make it look like one.
Factual error: In the first sequence, the family is in the house with the child in bed. It looks to be night. When they run from the house to the shelter, they scatter a flock of chickens. Chickens don't go outside after dark, even during eclipses and such.
