Revealing mistake: When Tori and others are fighting the leprechaun in the kitchen the wall phone rings and she picks up the hand set. It's the leprechaun on the line and in fear and anger, she slams the hand set back in place and tears the entire phone off the wall. As the phone rips away, it's obvious there is no phone line connector on the wall, only a nail the phone was hanging on.stevewaclo
Continuity mistake: After Ozzie and Alex leave the gold coin to be examined, when the shop owner looks through the book the back clasp of his suspenders is unclasped, then is clasped when he's at the stairs, only to be unclasped after he moves the tricycle, then clasped yet again.

Visible crew/equipment: Some equipment is reflected in the window of the cop car as it pulls out to chase the leprechaun. [It's a reflector screen.] (00:38:00)
Visible crew/equipment: The Leprechaun is on roller skates heading towards the white picket fence. As he gets close while the shot is over his shoulder, his shadow is cast on to the fence at the left edge of the screen. Problem is, a crew members shadow is right next to him for a split second right before the camera angle changes and he smashes into the fence.
Factual error: Although taking place in North Dakota, the Jeep and cop car have the older Illinois plates.
Continuity mistake: When the man opens the locker, the leprechaun jumps out and kills him by pogo-sticking him to death. He never pogo's on anything but the man's chest, yet the victim has big bloody welps all over his face.
Factual error: The movie takes place in North Dakota, but there are no tarantulas in North Dakota. (00:12:05)
Other mistake: After the Leprechaun has used the small car with the pitchfork and rammed the pick up truck, it rolls down the hill 3 or 4 times. The leprechaun opens the door and all 4 characters are not in the vehicle. They have not only managed to all exit the vehicle and hide behind a boulder but have all managed to not receive so much as a single scratch and Jennifer Aniston's hair is still perfectly brushed.The_Iceman
Visible crew/equipment: When the shop owner looks through the book for information about the gold coin, he hears the bike bell and when he walks toward the stairs, the crew's solid brown rug is visible on the blue floor - note its edges in front of the white bookcase. It is also seen when he walks back to the safe the second time. That rug is gone in all other shots. (This has nothing to do with the large patterned Asian-style area rug.) (00:35:45)Super Grover
Continuity mistake: When Nathan shoots the leprechaun after he entered out through the chimney, the leprechaun lies in different positions between shots. (01:05:30)
