Continuity mistake: When the Bandit first pulls over and picks up Sally Field, then he screeches off, if you look at the road you can see all the skid marks from all of the other takes of this scene, even down to the bit where the van pulls out of the junction and the bandit does his thing and then suddenly speeds off.
Continuity mistake: When the Bandit and Frog make the jump onto the field where the kids are playing football, the Trans Am goes through a chain linked fence then under a score stand. As it emerges through the wall, the antenna is broken, lying rearward onto the rear glass. The very next shot from the other side shows the antenna is fine and a few wood boards are around it. And when the boards fall off, this antenna falls off completely. The next time we see the car, a third antenna is in place again.
Continuity mistake: When The Bandit is getting ready to get in the convoy of trucks, right before he gets in between the trucks, all the trucks are close together. When they show a closeup inside the car, you can see the trucks are farther apart when you look out he back window. In the next shot when the cop car is pulling up, the trucks are close to each other once again. (01:16:35)TiggBoy
Continuity mistake: The odometer in the Trans Am is shown to have 1108.8 miles on it, rolling on up to 1108.9 during the shot. A little later during the movie, after they have travelled a considerable amount of miles, Bandit says, "We'll let's just see what he's got under the hood." A close-up of the speedometer shows the odometer is still on 1108.9.
Continuity mistake: In the scene where Buford T Justice is waiting in line behind a bunch of cars stopped at a car accident (in Alabama) there is a green Cadillac behind him, when he pulls off to the side to try getting through and gets stopped by the trooper, the same Cadillac is in the front of the line. At the very end of the film, when Bandit and Smokey are talking on CBs to each other, the same Cadillac is parked in the background, ahead of the red convertible that Bandit is driving...now in Georgia!
Continuity mistake: When sheriff Justice stops the kids in the van, his gun belt keeps appearing and disappearing. (00:22:25)
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.
