Leprechaun 2 (1994)

Continuity mistake: When the Leprechaun is telling his slave who tried to run away that it was his 1000th birthday. The scene is set a very long time before the first film, but in the first film he tells the cop that he is 600 years old.

Revealing mistake: When we see shots of the Leprechaun inside the safe, there is much more room than when he exits.

Revealing mistake: At the start of the movie where the Leprechaun makes the guy float up in the air with the gold thing around his neck, if you look up the top of the screen you can see two wires holding him up.

Morty: Didn't anybody ever tell you not to drink and levitate?

Morty: Nothing tastes as good as a free pizza. Now if I could only figure out how to get free beer.

Morty: They found this dead kid at Bridgette's, she's missing, everybody says you did it.
Cody: Me? That's crazy.
Morty: That's what I told the cops, now what the hell happened?
Cody: A leprechaun did it.
Morty: Maybe I should call the cops.
