Revealing mistake: When Fin decides to help the kids on the bus and says, "Water's rising, I'm gonna go up to the bridge and rappel down," two shots later the camera zooms in on Fin's car up on the bridge, but the problem is that this shot is shown in reverse - all the vehicles in both lanes are going backwards.
Revealing mistake: While Matt and Nova are up in the chopper, Baz loads the vehicle then asks Bobby how the front end is looking, and in the next overhead shot we can see that one of the center spokes has been removed from the front of the vehicle, but when Luellyn pushes Bobby out of the way Luellyn is skewered by that non-existent spoke - which was digitally added. The real spoke is back on in later shots.
