Continuity: Right before Ernest falls into his trash truck you can see that it is full of a good mixture of trash, i.e. white trash bags, food containers, etc. But when the camera angle cuts and he lands in the trash, it has now changed to all cardboard boxes.

Visible crew/equipment: When Kenny's dad drops Kenny off at the party, you can see a crew member in a ball-cap reflected off of the glass.

Continuity: When the troll eats the shells from the Sherrif's gun, he only eats about five or six, yet he fires over twice that many.

Revealing: When Ernest's jack flies out from under his truck it breaks the back windshield of the mayor's car. Watch closely and you can see the glass shatter before the jack makes contact with it.

Continuity: When Kenny and his friends enter the store on the bikes, Jimmy the employee calls Kenny "Kenny Barton" even though he knows that his last name is "Binder" in the film.

Visible crew/equipment: While Ernest is falling out of the back of the garbage truck in the beginning, the crew member's leg kicking the block of garbage on top him is visible for an instant.

Revealing: At the end, when Trantor shoots flames out of the ground to stop the crowd, the ground is split apart wide enough for the flamethrower to shoot flames out. The ground never shook apart or anything, because they show the ground before the flames shoot out and it's already split.

Revealing: When Trantor scratches the roof of the truck trying to get to Ernest, you can see that it is cloth ripping instead of the metal on the roof.
