Continuity mistake: At the Gator Motel, after Cledus and Bandit get part of the money, when Bandit starts crying about Frog and blows his nose into the money, there is a side shot showing a wad of bills in Bandit's shirt pocket before he actually puts the bills into his pocket in a following shot. (00:12:45)
Continuity mistake: In the scene where they go to Elwood's apartment, Elwood puts on a 78 RPM Decca Louis Jordan record. The record is entitled "Saturday Night Fish Fry". But the song that plays is "Let The Good Times Roll".
Revealing mistake: When Carl is caddying for the priest during the bad weather, the wind is so strong that it is almost blowing them over but the trees are not moving in the background.
Revealing mistake: In the dance sequence, we see Elaine twirling Ted around and throwing him into the crowd. Watch the top-right-corner of your screen, as the stunt-double lands in the audience you can see Robert Hays (Ted Striker) in the top-right-corner waiting to pop out. (00:19:10)
Continuity mistake: When at the poolside of the Bonaventure Hotel, Adam looks at one of the express elevators ascending. Then he turns and runs for the elevators, followed by the blue team. Miraculously, both elevators are now at the bottom floor. (01:40:55)
Continuity mistake: Gene Wilder's pencil disappears in the classroom scene. (00:33:30)
Other mistake: Tony Danza inserts the 8-track tape into the player but doesn't push it in far enough to click in and work. He also inserts it with his right hand but then his left after a cut.
Deliberate mistake: At the end fight scene, when they are in the barn one of the men falls crashes through the wall when they get hit, spilling the fight to the outside. Unless the barn's walls were made of cheap plywood, the wall would not have given away so easily. Obviously done for dramatic purposes.
Visible crew/equipment: When one of them is using the bathroom - out of the bathroom window and it sprinkles on his neighbor's flowers, watch when the camera view goes up because you can see someone squeezing a rag onto the porch banister to look like his pee.
Factual error: A film about the making of a film. A car is filmed going off a bridge, and the footage is played back repeatedly. Throughout, the car is referred to as a Duesenberg, even though, in nearly every shot, the Mercedes tri-sected circle logo is visible above the radiator.
Continuity mistake: When Kate ask if Sam Boga is scared to admit he's made a mistake, Sam Boga is carrying his rifle in his hand. When it cuts Sam Boga has his rifle shouldered. (01:24:00)
Other mistake: At the end of basic training, Judy's platoon goes to the bulletin board to see what their M.O.S. will be. This is not how the U.S. Army operates, you must pass a qualification test for the M.O.S. that you enlist for before you ever enlist. You know before you ever get to basic training what M.O.S. you will be training for, not on the last day of basic training.
Factual error: The middle third of the film recounts Dr. Thompson meeting Laszlo at the 1972 Superbowl (VI) in Los Angeles, however, in 1972 the game was played in New Orleans.
Continuity mistake: In the bullfighting scene Herbie's driver-side running board is dented upward in the middle, but in the following scene it isn't there.
Continuity mistake: Popeye goes to Bluto's ship. He finds his pappy there: he's tied to the chair hanging in the ceiling. Popeye gets excited, and notice that before he hugs his pappy he takes his pipe out of his mouth. When we see Popeye again, the pipe is back to his mouth. Too fast to be real.
Other mistake: Near the end of the movie, Dave Speed jumps onto Torpedo's private plane and starts steering it to the ground. The plane is white with obvious red stripes. However, Dave Speed is supposed to lose his super powers when he sees red.
Continuity mistake: At the end, the buried biker digs himself out of his grave and shuffles to the smokehouse. When he attacks Farmer Vincent, all the soil and mud stains have vanished from his clothing. Guess he must have stopped off at Zombies-R-Us for some fresh new duds. (01:30:00)
Continuity mistake: When it's driving on the road (in several scenes), the bus has a license plate. In the parking lot in the final scene, the license plate has vanished.
Factual error: It is established early in the movie (Natalie's call) that the money ball event celebration is part of the -first - anniversary of the Valley River Center, the shopping mall where most of the movie is set, with the town of Eugene, Oregon, mentioned explicitly. However, the center opened in 1969, and the movie is set in 1980. The original script was written in 1971, so that line needed an update and slipped by.
Continuity mistake: When the ladies are speeding down the streets, on the way to the hospital, Jane Fonda's coat belt hangs out the bottom of the door, or isn't there, depending on the shot.
