Continuity mistake: When Matrix is driving the red car and trying to run Sully's yellow car off the road, watch the front bumper of the red car. At some points it is hanging off the car, and at others is it attached onto the car.
Continuity mistake: At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide show, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the cost. Even if the boat was off camera during the landing scene, a few minutes was surely not enough to get that far, and that close to the shore.
Revealing mistake: When Matrix hits the button to blow up the village, you can clearly see that there are only cardboard stand-ups of men next to the buildings blowing up. Also, for some reason the top of the watch-tower blows up when Matrix never put a bomb there.
Continuity mistake: When Arnold lets go of the landing gear he lands in the water. A few seconds later we see him walking up towards the beach, and we can now see that he is only wet from his waist down. It's not likely that he would have been able to land standing on his feet and not not becoming completely soaked.
Continuity mistake: Rae fires a rocket at the police van, first she fires it back to front then the second time she fires it correctly only this time she is knocked back by the recoil, why wasn't she affected the first time and pushed forward? Also there should be no recoil with a rocket launch.
Continuity mistake: When Matrix first rips out the seat of Cindy's car and sits in its spot, his body sits very low to the the bottom of the car. You can even see in the next scene that his head is clearly lower than Cindy's. However, during the chase scene, his head is level with Cindy's.
Continuity mistake: At the end of the movie, Arnie puts on his flak jacket then his make-up, but when he takes off his jacket, he's got camouflage on.
Continuity mistake: After Matrix throws the police officer into the bunch of officers at the mall, he runs at Sully, and you see the guards are beginning to get back up on their feet, but then you see them again a few seconds later, and they are back on the floor again!
Visible crew/equipment: When Matrix and the girl are driving out of the parking lot you can see the camara crew in the reflection of the car.
Continuity mistake: When Sully flees the mall in his Porsche he runs into Matrix, knocking him up and over the car but also knocks off his wing mirror in the process. In the driving scenes that follow the mirror is back on the car.
Revealing mistake: Just before the guard in his tower gets killed and falls out, you can see the wooden sides have been precut. When he supposedly falls through the wood it parts along the cut line but remains hanging on string.
Revealing mistake: During the scene where Matrix is attempting to push his truck down the hill, pay close attention to the shot where the truck starts rolling and Matrix jumps into the cab - the cable controlling the truck is visible to the right of the rear tire.
Continuity mistake: When Matrix first abducts Cindy and is talking to her in the car, both of their windows are rolled up. When she backs the car out, the passenger side window is rolled down. In the next shot, as they exit the parking garage and pay the attendant, both windows are rolled down.
Continuity mistake: During the ridiculously overdrawn action sequence at the end, Arnie has a belt-fed machine gun which becomes lefty and righty through certain shots. Since Arnie isn't lefty, and it's unlikely that the army would just have a lefty belt-fed gun lying around, it's safe to say that the picture was reversed.
