Visible crew/equipment: When Helen's storm chasing crew begins to take shelter in the building, there is a shot of everyone running down the stairs to the basement. This shot shows Preacher run into something. It looks like a hand-held camera.
Continuity mistake: When Bill and Jo are in the truck, Jo looks at the dashboard, which is shown, and then Jo looks away and covers her eyes. Bill then floors the gas, and the dashboard is shown, and this time, the airbag light is on, unlike the previous shot of the dashboard two seconds earlier.
Continuity mistake: During a scene in the middle they drive the red Dodge solo into the hills to face a twister. As they bail out they find that they can't free the "Dorothy" from the back of the truck, so they have to run for it. As they look back they watch power poles start blowing up. Finally the one next to the truck goes and falls across the bed of the truck, smashing Dorothy onto the roadway and spilling the sensors. As they come back to the truck, because the twister has disappeared, they realise the twister is "jumping" and pile into the truck for their escape. The power pole is no longer resting across the truck and there is no damage to the bed.
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?
Other mistake: While in Wakita, in northern Oklahoma, the crew see the report of the F-3, and it was 30 minutes away. They meet the tornado in Texas, several hours away.
Suggested correction: The tornado is actually 30 miles away, not 30 minutes. Quite a difference for time.
Other mistake: Near the end after Bill and Jo have jumped out of the truck, their crew sees the truck and Dorothy go up in the tornado, they are receiving telemetry, then one of them notices the tornado shift direction and the crew still tries to notify Bill and Jo by radio, knowing they're no longer in the truck nor have radio communications.
Suggested correction: Jo still has her headset on. The crew can probably communicate with her that way, but she may not have been able to hear them since they were so close to the tornado in the cornfield.
Visible crew/equipment: When Jo and Bill are driving through destroyed Wakita, Jo looks at a family hugging on the side of the road. As the camera pans along them, the shadow of a boom mike is visible, gliding along them.
