Continuity mistake: During the opening scene when the family is driving down the road, a newer McDonald's can be seen on the right-hand side.
Continuity mistake: The helicopter that they use to rescue "dad" gets its windows entirely shot out. That is why the helicopter is put on autopilot so that the prison tower can be blown up. Later, everyone is sitting in the back of the helicopter talking and all the windows are intact.
Continuity mistake: The blue car gets pushed through multiple cars and is damaged. Shortly after in the same scene, the car magically appears undamaged.
Continuity mistake: When the ordered helicopters get close, there is a set of iron stairs in one shot blocking the door. A split-second later, when the door closes the stairs are gone.
