There’s always a scary side to every holiday.

You can thank Jennifer Aniston for some of the St. Patrick’s Day horror.

In 1993, Aniston got her first starring role in the low-budget cult hit Leprechaun.

That’s right. The A-list star got her first major gig fleeing a sadistic leprechaun while he angrily hunts for his missing gold.

Originally intended to be a fright flick for kids, the studio escalated the film's intensity and landed it an R rating.

By the end of its theatrical run, the movie had nabbed more than $8.5 million.

Leprechaun has scared up a loyal following, and is now a St. Patrick's Day staple on cable channels like SyFy.

It's a career move Aniston has joked about many times.

She made her debut on Friends the year following Leprechaun's release.

Since 1993, there have been six sequels to the original Leprechaun. Aniston is absent from all of them.

Here’s the film’s synopsis from IMDB:

When Dan O'Grady returns to the U.S. after stealing some Irish leprechaun's pot of gold, he thinks he can settle down and enjoy his newfound wealth. He thought wrong. The leprechaun followed him and O'Grady barely gets away with his life, having locked the little monster in his basement. Ten years later, J.D. and his spoiled daughter Tory (Aniston) move in. By accident, the leprechaun is released and almost immediately the annoying creature starts to look for his gold, not displaying any respect for human life.
