Revealing mistake: During the ending boat chase when Jimmy and Tom reach a small waterfall and go over it, their boats ramp up when they go off. There's no reason for them to do this other than stunt ramps put in place. And in several shots they go from nose up to nose down between shots. (01:33:01)
Suggested correction: As they pass under the bridge they enter a part of the river that has concrete dams inserted just below the surface of the water, we see marker bouys warning of the danger and the flow of the river speeds up. When the first boat hits the top of the dam it acts as a ramp launching it into the air and into a lower part of the river. The hull springs a leak because of the impact.
Continuity mistake: We see Sarah Jessica Parker well-dressed in red without a bra. When Bruce Willis remove her red robe, she's wearing a bra.
Factual error: During the car chase at the beginning, they are chasing a car on Bigelow Blvd., less than a mile from downtown Pittsburgh and we see a big, brick hill they chase down. This hill is actually in Duquesne, PA more than ten miles south east of Pittsburgh. Then as you're watching they are still in the same area as Bigelow Blvd., in the Polish Hill section of Pittsburgh.
Continuity mistake: In the bridge scene, Willis is seen without his crutch as he looks over the bridge at his fallen cousin. They cut to him beside the bridge and he has his crutch.
Continuity mistake: If you watch in the beginning of the movie you will notice during the car chase that various parts of the suspect's car fall off or get torn off and then in other scenes the parts are back on.
Continuity mistake: When Hardy is in the boathouse working with the map, the pen he lies down on the map changes positions as the camera angle changes and he never touches it.
Visible crew/equipment: When Bruce Willis is shown on the boat for the first time in uniform, some of the crew are reflected in his sunglasses.
Continuity mistake: Keep an eye on Bruce Willis' seat-belt during the chase at the beginning. It alternates between being on and off him.
Continuity mistake: During the various police car chase scenes one minute they would be in Mount Oliver in Pittsburgh, and the next minute they are in Mount Washington.
Continuity mistake: In the beginning, during the car chase, the Ford LTD they are chasing loses its front bumper, grill and several headlights. It even runs over the bumper causing a large spark display. But in the next shot the car just has lost two headlights.
Revealing mistake: When Hardy goes to check out a victim with Christman, Christman gets in the water to flip the dead woman over and the dead girl blinks her eyes.
Continuity mistake: In the car chase, when the cars go into the tunnel, Bruce Willis passes a taxi cab and several other cars, but then in a shot from the front you can see through the rear windscreen and see that there are no cars behind him.
Continuity mistake: Immediately after Hardy puts the taser in Jimmy's mouth, Hardy is bald.
Continuity mistake: During the first car chase scene, you can see that 5 hubcaps are seen coming off the truck from the left side throughout the scene.
Continuity mistake: When Bruce and Sarah stop the drinking kids in the fast speed boat, they confiscate a bottle of scotch. BW opens the bottle to smell it, then the scene goes to the partner and back to him and he UNSCREWS the top and dumps the liquor over the side. He opens the bottle twice.
Continuity mistake: When Hardy is waking up in the boathouse, after Jimmy jumps off of the bridge, look at the table with the alarm clock and phone on it. When he first wakes up there are no keys on the table. Camera angle changes and a set of keys has appeared on the table.
Revealing mistake: In the scene in the beginning where Jimmy is about to jump from the bridge, he is holding the cables holding the bridge up, which move and flex from his weight. Cables on suspension bridges are extremely tight from the weight and do not move at all if a person pulls them.
Continuity mistake: At the beginning of the film, during the car chase, Willis is not wearing his seatbelt; it is hanging loosely next to him. A little later it's suddenly on, with no time for him to put it on.
Continuity mistake: Jo is wearing a shirt and shorts when she boards the boat with Tom Hardy. Then she's wearing a red bathing suit and shorts as they chase the teens in their boat. Then she's wearing the shirt and shorts when the pass the large tugboat.
Character mistake: At the start of the car chase scene the dispatcher identifies the stolen car as an '89 Ford, but the Ford LTD Crown Victoria shown in the chase is a 1986 or 1987 model.
