Duel

Continuity mistake: On the truck cab's rear window, there is some sort of air conditioning unit installed. In some shots, such as the gas station scene where David Mann is on the telephone, or the railroad crossing scene, the air conditioning unit has a support structure to hold it in place. In the rest of the film however, there is not any support structure to be seen.

Continuity mistake: During the entire movie each time the camera pans on the car's speedometer, the odometer clearly show completely different numbers in the cars mileage which are thousands of miles apart.

Continuity mistake: As David Mann starts fuming at the guy who he thinks is the trucker, the first shot shows him taking a sip of his beer; it is almost empty. As he says "What are you talkin' about?" its almost up to the brim.

Continuity mistake: At the end of the film, David Man comes to a dead end, so he spins the car around and waits for the truck to appear. When the truck appears from over the hill, take a look at the very next shot of the truck from the front, and you will notice that the large exhaust on the side of the truck has moved from left to right and back to left again. (01:21:00)

Continuity mistake: There are moments in the film, notably during the railroad and pushing sequence where the car's appearance - such as being dirty or clean, changes somewhat; the truck changes during that sequence as well. (The film was first broadcast on TV, then later released to theatres, and the push sequence was specifically filmed for the theatrical release. An identical '71 Plymouth Valiant was used, but a very different truck.)

Continuity mistake: When David Mann is at the service station, window cleaner is sprayed on his windshield from the driver's side (camera shot from inside the car). Within a milli-second of the spray stopping, the service attendant is seen on the passenger side of the car. We are only shown one attendant at this station.

Continuity mistake: Near the start of the film, David stops at the gas station. We see him get out of the car and he asks the attendant if he has got change for the telephone. We can see David take out his wallet and pull out a note with the other hand, then puts his wallet away. Then the camera angle changes and his wallet is back in his hand again and he puts it away again. Also you never see the attendant take the note out of Davids hand. It just disappears. (00:10:45)

Continuity mistake: When David Mann crashes his car against the truck near the end of the movie, the car's frontal bodywork inexplicably returns as brand new in one shot and back smashed again.

Continuity mistake: When David crashes his car into the fence at Chuck's cafe, it shows that it was the passenger side that crashed into the fence. The driver side is undamaged. However when David exits his car to help the bus driver, there is significant damage to the driver's side of his car. (00:26:40 - 00:44:25)

Continuity mistake: When David Mann is flagged down by the bus driver, the window of the rear driver's side door is up. After Mann's 'just bounce it loose' speech, the window is down and remains down for the rest of the scene.

Continuity mistake: When David Mann is at the cafe, the waitress brings over his sandwich and water. He immediately drinks all of the water, yet when the shot changes to above the table, of him looking at his sandwich, the glass of water is completely full again.

Suggested correction: There is an empty glass next to the full glass.

The mistake is valid. David drank all his water before getting his food and asked the waitress for another glass of water and aspirin. She then brought him the food, aspirin, and 2nd glass of water. He drinks all the water after taking the aspirin and sets the empty glass down. In the next shot he's holding a glass with water. There should be two empty glasses.

Continuity mistake: After the incident where the truck driver told David Mann to pass, when there was a car coming the other way, watch the rear view mirror, it changes angles in the following shots.

Continuity mistake: Mann's '71 Plymouth Valiant has the ignition slot in the steering column. But in one insert shot of his speedometer as he races the truck at 100 mph, an older model's dashboard ignition slot is visible - with no key in it. (01:10:00)

Continuity mistake: When David drives away from the petrol station near the start of the film, you will see the truck catch up with him in the next scene. Take a look at Davids parcel shelf in his car when you see the truck fly round the bend, and you will notice a white baseball cap and a pair of sun glasses on it. They were not there before and also not there for the rest of the film. (00:14:20)

Continuity mistake: When David has the accident and crashes his car against the fences, he steps out of it and closes the door, but when he comes back to go on his own way, the car door is inexplicably open. (00:26:49 - 00:42:52)

Continuity mistake: In the first scenes when Weaver first encountered the truck he is pictured in various states of seatbelt wearing. In some scenes it's down and across, in others nothing.

Continuity mistake: Towards the end of the movie where David begins to take advantage over the truck driver, and he turns on right towards the climb also breaking the cartels and fences, the weather changes in two shots: it's cloudy before and sunny immediately after.

Continuity mistake: After the truck tried to make David's car hit by the train dabbing it from behind, the car has a dent on the right rear light, but in a following scene, the dent has vanished. (00:53:09 - 00:54:30)

Continuity mistake: Visible on the theatrical release. After David has overtaken the truck, you can see from the interior shot that David has his seat belt on. A few seconds later in the external shot David is no longer wearing his seat belt. (00:08:10)

Duel mistake picture

Continuity mistake: When David returns on his way after sleeping, he first wears his glasses in a shot, but when he suddenly brakes after seeing the truck stopped on the side of the highway, his glasses are gone. (01:03:07)

Visible crew/equipment: When David's car gets stuck on the bus bumper, the next shot is of the bus' black bumper and the side of the car. At the top of the black bumper there are two people seen in the reflection. The person on the left turns and takes a step to the right.

Answer: It's never explained why but, judging from the numerous license plates from other vehicles attached to his truck, the truck driver is a serial killer and was just targeting people at random and decided to make David his next target.

Trucks used to have to be registered in multiple states if they were going to operate in them. It was very common to see semi trucks with a half dozen or so license plates on them, each from a different state.

Answer: According to director Steven Spielberg, the trucker was a serial killer, and each of the license plates were trophies from previous victims.

Answer: David pulled ahead of the truck not once but twice. He got to the gas station first, and got served before the trucker. For any normal person this would not be cause to try to murder someone, however the truck driver is an unhinged psychopath who doesn't need much reason to go into an obsessive rage. Add to that the fact that David is driving a much smaller car, and the fact that they're out in the middle of nowhere with nary a cop around, and the truck driver probably saw David as easy prey.

Answer: "It was very common to see semi trucks with a half dozen or so license plates on them, each from a different state." And that's how the psycho trucker got away with it. He could have those 'trophy' plates on the front of the truck in plain sight, and to anyone who saw it, the truck would look like just another big rig with multiple license plates. Nothing out of the ordinary or suspicious about it.
