Continuity mistake: In the scene where they're leaving the school, there are a ton of cars behind them on the highway and then all the cars just disappear.
Suggested correction: Our heroes are in the last bus. There are a few cars exiting behind them, but you see at least one of the cars pass the bus and get ahead of it. In the first aerial shot of the highway, you can only see two cars behind the last bus. When the tower falls, it lands just behind the second-last bus, cutting off 3 cars, then our heroes' bus, then the Titus and another 2 cars. At no time is there a line of cars behind the last bus that disappears.
Other mistake: They had two cameramen, one meteorologist, and one driver who ran the imax camera. One camera man dies before they get in the church then when they talk about why he died you see another camera man or crew member holding a camera. He's seen twice then never seen again.
Suggested correction: Lucas, the 3rd cameraman, is in the background throughout (or we're seeing through his camera). He goes with Allison and the others after the church (Pete: "Suit yourself"); he gets out when they reach the industrial park, but is filming instead of helping rescue Donnie and Kaitlyn; he's behind Pete when they're all crammed in the Titus; he gets back in the Titus with Pete at the school (Pete: "Lucas, you getting this?"); and he's there in the storm drain and when they come out at the end.
