Dylan then pulls on the handkerchief and keeps pulling on it to reveal more coloured handkerchiefs until it stops and a timer is heard ticking. When the clicking sound is heard, Dylan is shown holding onto the knot between a purple handkerchief and a blue handkerchief. The shot then cuts to Agent Cowan saying "What is this?", but when the shot cuts back to Dylan, he is suddenly holding the knot between a blue handkerchief and a yellow handkerchief. Then in the next shot, his entire hand is held onto the blue handkerchief. (01:33:25)
Visible crew/equipment: When Drebin chases the doctor out of the hospital, the doctor gets a car, while in the background, Drebin falls from the ladder. Drebin then emerges from under the car. The doctor drives off, and Drebin enters the foreground. Look in the windscreen of the car Drebin emerged from. The top of a man's head with grey hair appears at the end of the shot, thinking it's over. This is the stunt double that dropped from the ladder. (00:32:25)
Revealing mistake: When Jack is hanging out of the truck you can see him standing on the hood of the car which Lydia is driving. At some points we get camera view from the back seat of the car.

Continuity mistake: After Inspector Todd is shot, Axel chases after De Wald and fires at the truck. When the guy at the back of the truck is shooting at Axel, we see multiple bullet holes near the truck's back right window, but in his close-ups the bullet holes are gone. The window frame's scratched paint differs as well in the close-ups. We know it's the same window because we also see him in the shot of the truck's interior.
Visible crew/equipment: After Phil drives the truck off the cliff, and it explodes in a burst of flames, there is a shot of Andie MacDowell and Chris Elliot staring in shock at the disaster.

Revealing mistake: When Bruce Wayne is heading to the hearing at the courthouse, he checks his revolver to make sure it's loaded. His intent is to execute Joe Chill for killing his parents, so he would need a working gun. But when he opens the cylinder of the revolver to make sure it's loaded, you can see that all of the bullets have had the primer removed (the end of each bullet casing has a hole in it.) This is done to make each round impossible to fire, for safety on the set. (00:22:55)
Revealing mistake: The stunt double's hairline is quite different than the actor's, when Bud White holds him over the balcony. (01:53:40)
Revealing mistake: When Jill and Cynthia meet by the water towards the end, Jill produces her gun and is told to throw it in. As she's holding it you can see the base of the grip and there's no magazine in it - hardly the most effective weapon... (01:26:45)
