Revealing mistake: During the finale when Remo is hanging off the log on the cable, when he drops to the bottom of the log, the harness cable holding the stuntman to the log is visible.
Continuity mistake: After getting out of the wrecked truck, Chiun had a door handle in his hand. While talking to Remo, and tapping Fleming's wrist to silence her, the handle is nowhere to be seen. In the long shot after saying "Lesson twenty-two, Blessed Silence", he suddenly has it back in his hand and tosses it into the wreckage.
Continuity mistake: When Remo walks away from the wrecked jeep, the ground is fairly undisturbed. When he tosses the burning branch, there is now a obvious ditch filled with fuel that leads to the jeep.
Revealing mistake: Remo picks a dry branch off a bush and rubs it to start a fire. When the angle changes, the branch has been dipped in a burnable liquid and easily lights up.
Continuity mistake: When Remo pokes out Stone's eyes, there's blood on his hand. A second later, it's clean.
Factual error: About an hour into the movie, while Remo is choking the guy in the car,a meter maid comes up and threatens to hit him with her nightstick. Meter maids in NYC don't carry nightsticks or any other weapons. They barely want them to carry pens. Also, she's repeatedly called officer, they aren't officers either.
