Other mistake: When the Tree gets blown under the red truck and they get stuck on it. Why don't they ever put the truck in 4WD? You can see the front differential and 4x4 markings so the truck definately HAS 4WD. That particular year of truck doesn't even require you to get out and lock the hubs.
Suggested correction: Character mistake more than anything. In a panic situation you don't tend to think of the obvious solution. The other issue to is that even if the truck was in 4wd that it might not have been enough. Keep in mind that the rear tires did burnout on a few attempts so the issue wasn't that the wheels weren't stable on the ground but that the tree trunk might have been too big to get the wheels over it by driving across (especially from the angle they were at).
Factual error: If an F-5 has enough suction to pick up a full gas tanker, why did it not pick up Bill's red pickup at the same time? It definitely had enough power to lift the tanker again, so it should've taken the pickup too as the tanker passed over it.
Other mistake: When Jo readies Dorothy IV on the back of the truck, she switches it on, but she never releases the rubber catches holding the lid in place.
Suggested correction: The rubber catches weren't needed to open the machine; they were only there to secure the entire lid in place. As seen when Jo is first showing how Dorothy works, the lid could be opened manually or automatically, depending on which button you pressed. As long as the pack was "set up" (sirens on and buttons activated), the pack would open automatically when close enough to the tornado, as shown when the pack lid opens at the end.
Continuity mistake: As Bill and Jo pass the camera position, the red lights on Dorothy are flashing. A moment later, Bill actives Dorothy, including the lights.
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.
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.
Continuity mistake: At the beginning of the drive-in scene Jo and Bill give each other a long look. During this you can see that Jo passes the same Pepsi sign twice.
Continuity mistake: When Bill & Jo leave the aunt's house in the red truck, it shows the truck has a back sliding window - the next shot there is no back sliding window.
Factual error: When the team is attempting to intercept the second tornado, Bill floors the gas pedal in the Dodge Ram after Jo expresses disgust at how slow he's driving. The next shot shows the dashboard, where the speedometer moves from 50-70 MPH, the engine is heard accelerating in the background, but the tachometer stays around 1500 RPM. The truck is an automatic and so it would have downshifted when Bill pressed the accelerator to the floor, and therefore revved much higher.
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.
Revealing mistake: The weather really is unusual in Oklahoma, as in some scenes, the cornfields were ripe and brown, and in others, they were fresh and green. Obviously shot at different parts of the season.
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.
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 see a red tab on the paper that she missed. In the next scene it's gone and in the next it's back again.
Continuity mistake: After the first twister they chase, Jo's hair is covered in mud and dirt. Then minutes later in the red truck her hair is clean and fixed nicely.
Continuity mistake: When all of the crew are heading to the F5 tornado, in the truck, you can see that the dog is in the front of the truck and at the same time, under a table on the back of the truck.
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.
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. (00:12:25)
Visible crew/equipment: When the crew is leaving Jo's aunts house, as the Red Dodge truck pulls out of the scene you can see the reflection of the camera and entire boom mic and pole in the 2nd window on the driver's side.
Continuity mistake: In the scene immediately before the gas tanker blows up in front of the truck, the passenger window of the truck is wide open. As the truck clears the explosion, the window is closed.
