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.
Continuity mistake: Right before the tree gets stuck on the axle of the red truck, there is a shot of the car turning. The tires are already chewed up from the scene coming up where they try to take off.
Visible crew/equipment: Near the beginning, Jo is in Beltzer's van fixing a wire. At the beginning of this shot, the camera moves down from high before she opens the door. As it's doing this, you can make out a reflection of it on the glass.
Audio problem: When Dusty is yelling for Melissa to look at the camera shot, he says "oh my God, oh my God." His mouth doesn't match up. He looks to be saying something far worse.
Continuity mistake: The sky changes multiple times when they turn onto "Bob's road", right after nearly running into Jonas' team. It goes from being very cloudy and gloomy to blue sky to cloudy and gloomy again in the space of seconds.
Continuity mistake: After Jo's truck is damaged, they switch to Bill's truck that has a cap on the bed, but the next scene shows Dorothy in an open bed of the truck. What did they do with the cap? You don't see it lying on the ground as the vehicles pull away.
Continuity mistake: During the movie theater scene all the vehicles except the bus and red truck are destroyed, but during the F-5 scenes all the vehicles are there.
Suggested correction: The vehicles remaining after the drive-in scene are Bill's red truck, Beltzer's van, Joey/Lawrence's Chevy truck, and Dusty's bus.
Continuity mistake: After the first tornado when Jo's truck is destroyed, you see Bill's truck with a shell on it. When their group is leaving the scene, the shell is gone and one of the Dorothys is in the bed. Where did the shell go?
Suggested correction: ANSWER; As some time elapses between the tornado aftermath and leaving the scene, there are plenty of reasons why the shell moved.
Visible crew/equipment: At Aunt Meg's house, Jo is taking a shower. There are two shots of her washing her hair. In the second one, the camera is blatantly reflected in the glass, left screen.
Continuity mistake: In the movie the antagonist Jonas has a vehicle fleet that includes the main vehicle, a Chevy truck, 4 black Dodge Grand Caravans, and a large recreational vehicle. At 37:15, a faraway camera shot shows the Chevy and 4 black minivans in a convoy, but the RV is nowhere to be seen. In the next shot, Bill, Melissa, and Jo arrive in the Red Dodge Ram, the RV is at the back of the convoy, and there are only 3 minivans between the RV and the Chevy at the front. (00:37:15 - 00:38:15)
Factual error: When they left Meg's house heading east towards Garfield county there are Texas county road signs.
Continuity mistake: The tornado before the one that destroys the drive-in theater rips power poles out of the ground. When Bill and Jo are arguing, we see a long shot of the road where the tornado was. The power poles are in place as if nothing happened.
Continuity mistake: When Dusty tries to get Melissa to watch a tornado through a camera, the way she holds her umbrella changes between cuts. Sometimes it's on her left shoulder, sometimes it's on her right.
Continuity mistake: When Dusty watches a tornado through a camera, the way he holds the camera changes between cuts.
Continuity mistake: When the tornado at the drive-in makes the sign with the titles of the movies fall, the arrow on the upper part of the sign is pointing to the left. However, when the upper sign detaches and heads into the garage, the arrow is pointing to the right.
Suggested correction: It's during a tornado. Things are going to be blown every which way.
Other mistake: During the movie, some characters wear a headset to communicate (Rabbit, Joey, Dusty, Jo, Jonas). Nothing wrong there, but they also use the CB radio/mic in addition to using the headset. And it's not so they can hear conversations better, since Rabbit and Jonas use the mic on their headsets 99% of the time. There are also instances where you can hear conversations from some of these characters when they don't use the CB radio, so the only mic that makes sense is from the headset.
Other mistake: How come it's the sunniest day ever a few feet from an F5 tornado?
