(at around 1h 21 mins) Near the end of the movie, the police car they take has a light bar and the word "Sheriff" on the rear fender, yet when they arrive in Louisiana, there is no light bar or printing on the car.
(at around 5 mins) When Sergeant Andrew Scott shoots the Vietnamese boy at the beginning of the film, the boy is wearing a green shirt. But when we see him from the back as Scott shoots him, his shirt is blue.
(at around 48 mins) Luc decoys the soldiers with the wooden "gas station attendant" mascot. But when the truck pulls up, the mascot is still standing where it was when we first saw it. As the UniSols approach, it isn't there any more.
(at around 1h 20 mins) In the canyon scene the weather is partly cloudy, however when the mobile command center falls off the cliff, the sky is clear blue. In the next shot, the sky is clear and taken near sunset, not in the afternoon.
(at around 1h 17 mins) When Andrew kills the prison bus driver, the bus goes out of control. During one of the scenes showing the bus weaving back and forth you are able to see the stunt driver steering it.
The Colonel commanding the Unisols is wearing a Special Force Green Beret incorrectly. An officer wears their rank on the flash on the front of the beret, the Colonel is displaying the Special Forces branch insignia like an enlisted soldier.
(at around 24 mins) Luc and Scott are sent to apprehend Veronica, the problem is that moments before they were sent to get her, they were naked and having their memory clearance injections. By the time they got kitted up to go get her, she would have already left and they'd have no hope of catching her.
(at around 42 mins) When Luc and Veronica make their escape from the motel, they drive through the office and interrupt the motel owner's mother reading a newspaper. Are we to believe she sat and happily read the paper during the previous sequence when the motel was shot to pieces by 4 heavily armed men?
(at around 1h 2 mins) In the diner, when Luc punches Hank (the cook), Brenda (the waitress) is inches away, laughing and distracted, but she manages to duck in perfect sync when the punch is coming, revealing that the fight is an obvious choreography.
