Other mistake: In one of the first scenes where Sylvester Stallone is sitting astride James Woods and pummeling him with his fists. His last blow is from his left hand and it goes over the head of Woods - a visible miss. Yet Wood's head jerks to the side.
In the first scene, when Sylvester Stallone is in Colombia, the city that is named is Bogota. But that is impossible, Bogota is a metropolis of 7,000,000 people, one of the largest and most developed cities in South America, not a jungle.
