In the movie Leprechaun, the titular character is played by Warwick Davis and is depicted as a sadistic, violent creature who is obsessed with his pot of gold coins. The movie opens with an elderly man finding the Leprechaun's gold and stealing a single coin, which unleashes the creature's fury. The Leprechaun begins killing anyone who gets in his way, using his magic to torment and terrify his victims.
The plot centers around Tori (played by Jennifer Aniston in her feature film debut), a young woman who has recently moved to the town where the Leprechaun is wreaking havoc. Along with her friends, including a dim-witted repairman named Ozzie (Mark Holton), Tori finds herself pursued by the Leprechaun and desperately tries to find a way to defeat him.
Throughout the film, the Leprechaun uses his powers to transform into different objects and animals, including a tricycle, a pogo stick, and a gruesome giant spider. He also uses his charisma and trickery to confuse and deceive his victims, often pretending to be harmless before revealing his true intentions.
As Tori and her friends search for a way to defeat the Leprechaun, they learn that the only way to kill him is by finding a four-leaf clover and sticking it in his mouth. This leads to a tense and terrifying final showdown, in which the Leprechaun unleashes all of his powers to try and prevent the group from getting the clover.
Overall, Leprechaun is a horror-comedy that combines traditional Irish folklore with elements of slasher films. The film spawned six sequels, with Davis reprising his role as the Leprechaun in all of them.
