Continuity mistake: After chasing down Sully, the yellow Porsche is totally wrecked on the left side, until Arnie drives it away, and it's fine. Later, when Arnie and Cindy arrive at the hotel, the car is wrecked again. (00:39:50)
Audio problem: When landing the seaplane, Cindy says, "Ok, here we go," yet her mouth doesn't move. (01:02:20)
Continuity mistake: When Matrix is firing out of the sea plane, he shoots 2 people in a jeep. In one shot, they are both falling backwards having been shot, and in the next shot, the one in a sand-coloured top is jumping out of the jeep. (00:58:10)
Continuity mistake: When Cindy is about to shoot the police van, the damage to the van door changes between consecutive shots before the explosion. (00:54:50)
Revealing mistake: When Cindy fires the second rocket at the truck, you can see the explosive device on the road next to the truck just before it gets hit. (00:54:20)
Continuity mistake: Just as Matrix says about growing up in East Germany, his daughter has her hand on a glass of juice. However, as the shot changes, she is now holding her sandwich with two hands. (00:07:40)
Continuity mistake: When we see Cindy coming in to land at the island, her grip on the throttle changes from the back to the front angle. Note her thumb and the gap between her thumb and index finger. (01:02:30)
Continuity mistake: When the army helicopter lands, a person gets out on the left-hand side and moves in front of the glass window of the door that's open. Camera changes and he emerges from the helicopter again. (00:09:10)
Revealing mistake: Just before we see the boat explode at the start, a wire/cable holding the boat in place can be seen at the bottom of the screen. (00:04:10)
Continuity mistake: At the start, the way the right hand binman holds on differs between shots. (00:01:50)
Factual error: If the access hatch to the nose wheel well on an airliner was opened at any time during the flight, every alarm panel in the cockpit would light up like a Christmas tree. In this case happening within seconds of takeoff the pilot would immediately declare an emergency, turn around and land at the airport he had just left. (00:22:10)
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. (00:39:50)
Continuity mistake: At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide shot, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the coast. 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. (01:20:30)
Revealing mistake: When Matrix hits the button to blow up the village, you can 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 also blows up even though Matrix never put a bomb there. (01:11:00)
Revealing mistake: In the siege at the end, there is a shot where you can hear the squibs (small charges that explode on a stuntman to make it appear he was shot by a bullet) going off on one of the soldiers as Matrix shoots him. (01:13:10)
Factual error: The shot of Matrix landing in the swamp after jumping from the plane isn't consistent with the free fall. The final shot indicates he has not fallen more than a couple meters. On top of that, after jumping from a DC-10 doing over 150 mph, he has no forward momentum when he lands. (00:24:39)
Visible crew/equipment: When Matrix is holding Sully over the cliff, you can see the cable holding him up. (00:40:51)
Continuity mistake: During the shooting scene by the mansion, the same poor soldier gets killed from different angles, again and again and AGAIN.... (01:12:34)
Continuity mistake: At the start of the film we see two guys on the bin wagon. The one on the left of the screen already has his Uzi in his left hand, yet in the next shot we see him lean into the back of the bin wagon to pick it out. (00:01:45)
Continuity mistake: When Bennet and Matrix are fighting at the end. Bennet has his hand over Matrix's face. During instant camera cuts, the position of his hand alters on Matrix's face and neck. (01:18:55)
Answer: Possibly so any surviving enemies they encountered on previous missions and or tours of duty couldn't hunt them down and kill them for revenge.
