Continuity mistake: In the boat chase scene with Dirk, Al and Rudi, the glass at the front of the boat gets shot out and then appears intact in the next scene, but is shot into pieces seconds later.
Continuity mistake: Dirk, Al, and Eva are trapped in the Civil War ironclad. Dirk sends Eva to find fuses for the 150 year old cannon on board the ship. She runs across the room, falls through rotten decking to the deck below and is completely covered with sand. In the next shot as Eva gains her composure from the fall, the sand has disappeared.
Continuity mistake: When Eva is being choked, at one point the guy is choking her on her bare skin and in another shot, she is being choked over her shirt collar.
Continuity mistake: When Dirk is talking to the rebel leader, while he is loading up the truck, his arms go from being down by his side in one shot to instantly having his hands on his hips in the next.
Continuity mistake: In the first boat chase scene a truck comes along the bank of the river with a machine-gunner on the back. When the driver of the vehicle is shot by Rudy with the flare gun, the truck is seen and smoke pours out of the truck's cab to the point where it's hard to see the machine-gunner on the back. Then in the shot where the truck is seen from the boat, there is no smoke at all. Then in the shot of the truck, the smoke is pouring out of the truck's cab again.
Continuity mistake: The guard sitting on the back of the train has sweat covering the front of his shirt. In the next shot, the sweat is gone.
Continuity mistake: When the Admiral's friend from the CIA leaves after pouring the water for the bad guy at the restaurant, he gets on the elevator and takes his tie off. When the angle changes to the bottle of water and the elevator goes down, his tie is back on.
Continuity mistake: When the boys are tied in the pickup truck, the truck is moving forward. In the first top down shot of the boys, if you look closely at the ground the truck is moving backwards.
Continuity mistake: In the scene where the Admiral is asking his CIA friend for a favor, in one shot it isn't raining, the next shot has rain, and a third shot goes back to it not raining.
Continuity mistake: At the end of the film the waiter/agent serves up a glass of bottled water and gets in the lift, once in there we see him remove his bow tie but when we see him go down in the lift he's wearing the bow tie.
Continuity mistake: When Rudy shows up to the dirt house with the other guys after the Panama boat scene he walks in barefooted. As the shot goes back to include his feet he magically has sandals on. (00:46:11)
