Factual error: Rico lives in Buenos Aires, which has no hills within a couple of hundred miles. The city shown in the film has hills.
Factual error: When Rico is whipped, the guy with the whip is shown about 15 feet in the background. The lashes leave huge 18-inch stripes on Rico's back, implying that the whip is about 17 feet long. But the maximum effective striking length of a whip is only 12 feet, at most.
