"Insidious: Chapter 3" hits theaters today and is the latest installment in the hit low budget horror franchise. Directed by Leigh Whannell, writer of the first two movies, it is a prequel to the previous films. It shows how Lin Shaye's character, Elise Rainier, came to meet Specs and Tucker and the trio dealing with their first haunting together.

Looks like Blumhouse and Focus were the only ones revealing much at WonderCon to the public. Last night they showed off the first teaser trailer from “Sinister 2” and today they revealed the first clip from “Insidious: Chapter 3,” two supernatural horror franchises the studio hopes to eventually connect ala the Marvel shared universe model (points for originality of course). The third chapter in the “Insidious” series is a prequel and stars Dermot Mulroney, Stefanie Scott, Angus Sampson, Leigh Whannell and Lin Shaye. The directorial reins of the series have been passed on too.

Focus Features just recently pushed back the release of Insidious: Chapter 3 to the summer of 2015, but we only knew one cast member and didn't have any story details. That changes with the beginning of production and a first look photo announcement revealing that Dermot Mulroney will also be joined by Stefanie Scott (of Blumhouse Productions' Jem and the Holograms) and returning cast members Lin Shaye, Angus Sampson and Leigh Wannell (who is also directing in place of James Wan).
