Other mistake: Early in the movie, when Neville wrecks his car he takes the gas can out of his car and starts walking down the street. As he does they switch to a wide view of the city in which you see about three city blocks. When you look at the only "through" street in the shot, there is a car making a left hand turn about three blocks down that street and just behind the car is the freeway overpass with two or three cars passing on it, before the shot ends.
Other mistake: When the man at the start is thrown through the room and his head hits the wall, the picture briefly freezes.
Other mistake: When Cornelius and Zira should escape through the mechanical door that is opened by a knob in the guard's box there is no way that Cornelius could see which knob he should press, because one of the guards has his face turned to the window that they are hiding under.
