I'm Salvadoran, a Few Facts about this Film
Everything was accurate on the film, the roads, the violence, the army incidents, even roadside advertising posters depicted in the movie, but there were also gross and preposterous falsehoods, here are a few:
--Mexican accent being spoken by every "Salvadoran" in the movie (this doesn't look bad nor matters among anglo viewers since they can't tell the difference between the spanish of one country to another but for bilingual viewers it was very sad).
--The film was overtly pro-leftist. The guerrillas were portrayed as homely liberators getting themselves rid of a tyrannical government, that's far from the truth, half the rebels were common criminals and others joined just to get rich quick and to steal with their new-found power of carrying weapons.
--The army was portrayed as brutal, it was brutal, but so were the rebels who blatantly killed many innocent people, in some instances just to take over their ranches and houses.
--The movie depicted a cavalry battle, oh my gosh, is Oliver Stone for real? There isn't a single instance in the war where horses were used to charge against tanks or army bases, not even one instance.
--The scene of the Archbishop being killed was distorted, in the movie he was shot point-blank by a guy who had just taken the oyster in his mouth kneeling before him, in reality the Arhcbishop was killed by a sniper that was on the last bench near the back exit of the cathedral. He used a long-barreled rifle.
Hope this clears a few things up :)
