Factual error: Near the end of the film, after Ditch and Krista use the reserve parachute, they fall in a windfarm. The windmills are spinning fairly slowly. After the fight Ditch pulls Pinkwater's parachute out. The wind pulls Pinkwater back towards the fan. Before he gets chopped up there is a shot of the fan blades spinning very fast and powerfully. A light breeze would not cause these blades to spin in this fashion. A hurricane would be needed for those blades to chop up a human.
Continuity mistake: At the end the amount of blood around Ditch's mouth changes from shot to shot.
Factual error: When the car is loaded on the plane near the end it is not secured in any way. Upon take off this would have smashed through the back of the plane or badly damaged the rear loading doors causing the plane to land, we know this as Ditch jumps in it later and drives forward, pinning the bad guy to the bulkhead, then he reverses out of the plane.
Continuity mistake: After smashing through the giant fish tank, both men land on the floor and are wet. Although there were several hundreds of litres of water in the tank there is none on the floor, or when Ditch runs out, the floor does not even look wet.
Continuity mistake: In the fight with the bad guy at the dead girl's apartment, Ditch gets thrown into a glass top coffee table and a close up of his face shows a big pane of glass resting on him and the side of the table. In the next shot when the bad guy pulls him out, the glass is gone and Ditch has not moved.
Continuity mistake: When they meet the girl at the junkyard, Ditch walks over to her when she gets out of the plane. The bad guy with him puts his right hand in his coat as if to pull out a gun, it cuts to see the two men from behind and the bad guy has his right hand down by his side, cut to a front shot and his right hand is back inside his coat.
