Revealing mistake: In a scene where Frog is riding with the Bandit, she's resting her head on the center gearshift console. Although they're supposed to be cruising down the road, the automatic transmission shifter is in neutral.
Revealing mistake: When "Pop" dies, you can tell he is still breathing, especially if you fast forward the scene. He is just doing it very slowly, but you can see his chest move up and down.
Revealing mistake: While in the convenience store, watch the arcade screen the punks are playing, they are getting very excited about the game, however anyone who has played Street Fighter 2 will notice that they are merely looking at the demo version and even the words "insert coins" are displayed on the screen.
Revealing mistake: In the scene where Jane is trying to run over John with her car, she jumps from the driver's seat while John is in the back of the car. Right before the car crashes through the fence, you see John through the back window. You also see a head in the driver's seat, even though no one is supposed to be driving the car.
Revealing mistake: When Goldie Hawn pushes Kurt Russell off the boat you can see he has flippers on in the water.
Revealing mistake: Near the very end of the movie, when Magua has taken Uncas' love interest (Madeleine Stowe's character's sister) and he is taking a path through the mountain, Daniel Day-Lewis runs up a path and brushes against what seems to be a rock. But, the grey coloured "rock" seems to be a prop and moves like a piece of cloth.
Revealing mistake: Doesn't it seem odd to anyone that the crops hadn't been reaped by Thanksgiving in South Dakota?
Revealing mistake: The stepmother's arm disappears for a split second when she tells her daughters that there is still a chance for them to become the princess.
Revealing mistake: The professor has a blowout, but all four tires on the car are fine. (02:04:30)
Revealing mistake: When Natalie Portman's character is about to be executed, if you look at the wall behind the executioner, you can see a modern metal drainpipe.
Revealing mistake: When we first see Max, his paws are leaning on a balustrade and become transparent. Though it may seem like it's an optical effect because they're in the shadows, the next angle shows them fully lit and opaque.
Revealing mistake: In many scenes, particularly the dance scene in the bar, Michael's wings disappear and/or reappear. If you look closely throughout the movie, his wings are often completely gone.
Revealing mistake: In one scene, when Jack is in the dungeon talking to the fairy, you can clearly see that the "fairy" is nothing more than a light on a thin piece of wire. The wire can be seen quite clearly for two shots.
Revealing mistake: About 30 seconds into the movie, when the camera is panning down the flight status board, the letters are flipping through to form the correct words. However, the board is digitally animated, and some of the sequences of letters scrolling (such as one square going from L to M to N) loop without making any sense, like in the line above the yellow "The /Terminal" (U, V, W, U, V, W, U, V, W.). (00:00:30)
Revealing mistake: There is one scene where Alicia Silverstone is being taken away, and in the window, in the background, you can see a metro train with the letters on the side stating BC Transit and a picture of the British Columbia flag. Yet, the whole movie supposedly takes place in Washington state.
Revealing mistake: In the early part of the chase scene, when the person hanging the banner swings into the pane of glass, you can actually see it start to shatter before he touches it.
Revealing mistake: When the Charger hits the red truck, the truck turns over with the assistance of a 'pipe cannon' (note the sudden eruption of white smoke from under the truck). This device is like a large gun, pointed down that fires a cylindrical wooden 'bullet' at the ground, and the pressure behind it forces one side of the truck upward, causing the flip. Evidence of its use is seen when the passing cop drives away and in the street is a perfectly circular 'dent' in the asphalt with a burn mark surrounding it. (01:12:50 - 01:16:20)
Suggested correction: A cannon roll uses a large device, usually a metal pipe that is pointed down, but it does not fire a "bullet" wooden or otherwise. It is just the force of the explosive charge focused downwards that causes the cars to roll over.
A cannon roll shoots out a wooden log to flip a vehicle, it's not just shooting out air.
This is just nonsense, a wooden log would be too dangerous to use, would be highly conspicuous on screen, and would take up room inside a vehicle.
Then you don't know how they use to do car stunts. It does take up room, but even modern methods do. Cars have to be modified heavily and of course it's dangerous, they're flipping a car with a driver inside. Film makers do everything they can to avoid the stunt car from being detected (just the same way they do everything that can to avoid a dummy being detected). Here's a article that talks about car stunts before the pneumatic flipper.

Bishop73 is right. For example, from Raiders of the Lost Ark: https://www.moviemistakes.com/picture6238.
Revealing mistake: When McKay and Ramon are riding into Blanco Canyon to rescue Julie, you can see a diesel loading shovel with its bucket raised in the bottom of the frame of one of the scenic shots. Presumably the scene was shot in a quarry and they didn't get all the equipment out.
Revealing mistake: When Shrek and Donkey are sitting by the fire and looking at the stars, when Donkey asks Shrek about "our swamp" and Shrek says "We?" When Shrek blinks, his right eyeball is slicing through his upper lid. (00:46:30)
Revealing mistake: When Gary and Wyatt come home and see Chet turned into a pile of poo, Chet shoots his tongue from his mouth and catches a fly. Look closely, the tongue flies completely out of his mouth and is attached to a metal spring. (01:24:55)
