Continuity: During a fight scene with the Leprechaun you can see a very noticeable difference in height between Warwick Davis (Leprechaun), and his stunt double.

Revealing: After the Leprechaun kills Mrs. O’Grady, she is leaned up against a table. After Mr. O’Grady shoots the Leprechaun, he walks over, past his dead wife, who clearly blinks.

Continuity: After Nathan pours the gasoline and throws the match in the well, we see a canister and shotgun sitting by well. But when the well explodes, they’ve disappeared.

Continuity: As the guys are searching for the Leprechaun in the basement, Alex removes his red cap twice.

Revealing: The ‘bear trap’ clearly has no spikes in it, so how could it have wounded Nathan. This is ever so clear when Tori prises the bear trap open to get his leg out, and it snaps back.

Continuity: O’Grady opens the cardboard box and pulls out the soft paper from inside, and throws it to the side, into the bush. In the next shot the paper is back on the table, behind the box.

Revealing: Near the end of the film, when the people are in the house fighting the Leprechaun, one of the characters is using a shotgun. The Leprechaun rides up and down a hallway on a skateboard and the character with the shotgun shoots at him, missing not only the Leprechaun, but everything else as well. Unless he was using a round full of confetti that I've never heard of, he should be shooting the wall and everything else in sight, yet nothing at all is hit.
