Ju-On: The Grudge is a 2002 Japanese supernatural horror film written and directed by Takashi Shimizu. It is the third installment in the Ju-On series and the first to be released theatrically (the first two being direct-to-video productions). It stars Megumi Okina, Misaki Ito, Takashi Matsuyama, and Yui Ichikawa.

However, the sequel to the first film, The Grudge 2 is not a remake and follows a different storyline albeit still drawing inspiration from several Ju-on films. The most recent sequel The Grudge 3 picks up after the events of the second film.
