Corrected entry: In the scene at George and Martha's house, Carnegie calls for Eli to throw out the book. A wrapped object is thrown out of the second story window and lands a few feet in front of one of the gang's cars. Redridge picks up, unwraps, and opens the object, and, hearing a click, throws it back on the ground in front of the car, running away from it. . In the next shot, there is an explosion, not where the object lays in front of the car, but from the side of the car opposite the camera.

Correction: Actually, if you watch the scene again, after the guy unwraps the book and hears the click after opening it, he drops the cloth straight on the ground, and while turning to run, he does indeed toss the explosive behind the car in question. If you look while he opens it, they are between the set of vehicles, so I would have to declare this "Mistake", NOT a "Mistake"
