EXCLUSIVE BREAKING: Bloody Disgusting has learned that Ghost House Pictures and Mandate are currently developing another remake of the Japanese Ju-on franchise.
Before the 2004 American remake, The Grudge, Ju-on was originally released as two low-budget straight-to-video Japanese television movies in 2000. Three years later, due to the success of the videos, Takashi Shimizu, director of all, made a theatrical version based on the videos, titled Ju-on: The Grudge.
Now, it gets tricky as that version spawned a sequel titled Ju-on: The Grudge 2. A year later Takashi Shimizu directed The Grudge, an American remake. It is based on the theatrical version of Ju-on, but it contains scenes re-enacted from all of the Ju-on movies. (Wikipedia)
Continuing the franchise into infamy, Ghost House released The Grudge 2 theatrically in 2006 and The Grudge 3 direct to video in 2009.
Next up, another reboot, although it's unclear to Bloody if this is to go direct-to-home video or hit theaters. A Grudge 4 was originally debunked back in 2009. This will mark the eighth film in the franchise.
