Factual error: When the Snowman is figuring out their schedule and he is typing on the calculator, you can clearly see that it's off. (00:18:15)
Continuity mistake: When sheriff Justice stops the kids in the van, his gun belt keeps appearing and disappearing. (00:22:25)
Continuity mistake: When Buford T. Justice's top gets knocked off his car, at the end of the shot his head starts to emerge from the car and some sunglasses but when the car stops a split second later Buford isn't wearing any glasses.
Factual error: When Justice is talking to Sheriff Branford of Deason County Arkansas, Justice is told that he is out of his Texas jurisdiction. But a sign behind Branford tells us that Branford is also a long way from home, as the sign indicates he is in Willow Bend, Clayton County, in Georgia (where this scene was actually filmed).
Continuity mistake: In the scenes where Sally Fields is removing her wedding dress and veil and throws them out of the car you watch the veil leave the car and fly away, in the very next scene the veil is back inside the car as she struggles to get it to fly out of the car again, as it is caught on the t-top.
Continuity mistake: In different scenes the rear view mirror is shown and then it is gone. This happens several times throughout the movie.
Continuity mistake: Every time they show how fast the car is driving, there's fewer miles on the odometer...
Visible crew/equipment: When Snowman is pulled over by "Mr. Evil Knievel" (the cop) two lighting reflections can be seen in his helmet.
Continuity mistake: While at the truck stop to refuel, the Bandit talks to Justice on the CB. During this scene, Justice is having his car worked on the front is up on a jack. When the bandit drives by them to leave, you can see Junior is wide awake (in fact, his head turns to look at the car) and then immediately in the next shot he is sleeping.
Continuity mistake: When Snowman plows into Sheriff Justice, he causes Buford's car to spin clockwise. In the very next shot, Buford is spinning counter-clockwise. If this were to happen in real time, Buford would have rolled over. (00:32:45)
Revealing mistake: In the chase scene with the cop taking a "10-100," the patrol car loses control and goes backwards into a lake. But if you look closely as it plunges in, you can see the backup lights lit, which is impossible if the car was in drive.
Factual error: When The Silver Tongued Devil contacts Bandit for a smokey report, he asks if the Bandit is "coming up on Fayetteville, on Interstate 82." Aside from the fact that Fayetteville, Arkansas is far off the direct route from Texarkana to Atlanta, Interstate 82 is about 1900 miles away from Fayetteville, in Washington state. In fact, at the time, there was no interstate highway at all near Fayetteville, Arkansas.
Continuity mistake: In one shot near the beginning the bandit is being chased by the first of many cops, he comes to an intersection and turns left. But if you look close you can see that he actually turns the steering wheel to the right .
