'Insidious: Chapter 3' Plot Spoilers, Release Date [PHOTO]: Next Horror Movie Franchise Film Is Prequel, 2014 Production Starts - Expect Official Teaser Trailer Soon

Another popular horror movie franchise is getting the prequel treatment, though it won't be a standalone film. Insidious: Chapter 3 will apparently predate the previous two horror films about demonic interference in a family's life, and tell a completely different story as the next chapter of the series.

We recently reported on the trailer for Annabelle, a spinoff prequel to The Conjuring. Read more on this HERE!

The news of these plot details comes from a press release from Focus Features. Here is an excerpt:

Insidious: Chapter 3 stars Dermot Mulroney (of August: Osage County) and Stefanie Scott (of Blumhouse's upcoming Jem and the Holograms) alongside Lin Shaye, Angus Sampson, and Mr. Whannell, with the latter trio reprising their roles from the first two movies in the franchise. In Insidious: Chapter 3, a twisted new tale of terror begins for a teenage girl and her family, predating the haunting of the Lambert family in the earlier movies and revealing more mysteries of the otherworldly realm The Further.

Along with the plot details announced this week, Focus Features also revealed details of a contest to win a chance to visit the set of Insidious: Chapter 3. Running from Tuesday, July 22nd, to Friday, July 25^th, fans of the movies can enter to win HERE!
