The third chapter in the Insidious story has its release date. Insidious: Chapter 3 is set for release on April 3, 2015. This is yet another addition to a very crowded 2015 release year. With this date it will be in direct competition with Passengers which stars Keanu Reeves and Rachel McAdams.
As of right now we know that Leigh Whannell is set to return to write the script and possibly re-appear as Specs. However, we have no potential plot and it is extremely unlikely that James Wan will return to direct. Wan is currently directing Fast and Furious 7 and announced this summer that he wants to move away from the horror genre. Wan had two horror releases with Insidious: Chapter 2 and the record breaking film, The Conjuring.
I feel like this is both good and bad news. I think Whannell and Wan know better than anyone how far a horror franchise can go. Look at what happened with Saw. I don't want the same to happen with Insidious.
