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.

Visible crew/equipment: When the twister is heading for the drive-in movie theater, as Bill is running towards the garage, you can easily see the shadow of the Steadicam operator and a grip guy on the ground about 2 feet away from Bill's shadow.

Visible crew/equipment: When Jo is taking a shower you can see the reflection of the camera in the glass in one quick shot.

Visible crew/equipment: When Jo shuts her door after setting up Dorothy III during the final monster tornado scene, the heads of three crew members are reflected in the silver window frame.

Factual error: Notice that all of the cars passing and honking at them have the same horn that sounds like a 70's import, even when some of them are pickups and larger cars.

Factual error: When Jo and Bill drive through the house pictures are still on the wall, a chair is still upright and the towels are still hanging perfectly on the rack in the bathroom. Pretty cool considering the house had just been tumbling through a field.

Continuity: When we see Melissa at Aunt Meg's house, she is in the same 3-piece white suit she's been wearing since the start of the movie and it is still spotless - even after Bill, dirty, muddy and wet from the first tornado, hugs her.

Continuity: 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: When Bill and Jo are in the yellow pick-up going after the first tornado, there is a yellow raincoat with a visible metal snap hanging from a hook mounted on the rear window directly behind Jo. As the scene progresses, it moves to a position higher up and off the window when Jo says, "We're moving to intercept, guys. Get ready to set up." Then Bill gets off the road and down into the ditch, right before Bill says, "Are we having fun yet?" the raincoat is back hanging from the hook on the window behind Jo in a different position (no snap visible).

Continuity: In the scene where Bill is loading the newly modified sensors (with the aluminum can "propellers" on them) into Dorothy, Dusty hands him the first box and when Bill dumps them, Dorothy appears to be full - some sensors even pile up and spill out. But subsequent boxes are dumped with no problem; Dorothy is not nearly as full.

Other: During the movie the actors use radios all the time. They talk to each other and others talk and everybody hears it over the radio like they are all plugged in to a single radio. If everybody talks at the same time over a radio channel from different transmitters all you would hear would be a lot of garbage from all the mixed signals. Jo and a few others wear radio headsets for 47 MHz radios and we can hear them over the CB radios in the vehicles on 27 MHz. If everyone is supposed to be able to hear each other over the radio, why does Jo always have to change the CB channel, wouldn't they all be on the same channel?

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.

Continuity: In the first shot of the red Dodge trucks instrument panel, note the miles on the odometer, then LATER in the movie it is shown again, this time with fewer miles than at first.

Continuity: Towards the end of the film when they are preparing Dorothy 4, the twister behind them is about 5 metres away. Then it it much further back the next time we see it.

Continuity: In the first sequence, they 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: In the scene where 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.

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.

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: While driving the red truck through the rolling house, Dorothy is mounted on the back of the truck. There are some very sensitive and fragile instruments located on the top sides of Dorothy that stick up above the cab of the truck. These would certainly have been torn off while crashing through the walls of the house, turning Dorothy into a useless pile of junk.

Continuity: When they are driving in that jeep, the window gets shattered at one point, and then they literally DRIVE THROUGH a house and then as they come out, the window is intact again.
