Factual error: The school bombing in the beginning of the movie takes place in a local public school (public schools in the Philippines are designed with a yellow roof with green letterings written with the locality's name). Expats ARE NOT allowed to enroll their children in Philippine public schools for the obvious security implications.
Continuity: At the beginning of scene 20, when the soldiers are tucked down in the two dump trucks, two soldiers are shown lying in the bed of the truck with a very low rear gate on the truck (you can see the ground behind them, just above their heads). A little bit further in the same scene, it is apparent that both dump trucks have taller rear gates that are equal to the sides of the truck bed.
