A new behind-the-scenes still of Dermot Mulroney in Insidious 3 was recently revealed.

Insidious 3 To Be "Special," Like A "Specter Of The Further"?  

"We take you back to the beginning. Dermot Mulroney on set of the next #Insidious coming summer 2015," the tweet states on December 9.

The official trailer for Insidious: Chapter 3 released on October 22 and is tagged as "the darkest chapter" which goes back to "the beginning."

Fans "Will Love The Continuation" Of The Horror Franchise 

Mulroney is seen playing Sue's (Stefanie Scott) father, and the clip starts with her being wheeled in by her dad as she has a fracture. They settle into their new apartment appreciating the neighbors but all's not well, in this seemingly normal space. As Sue resigns for the night in her bedroom the eerie business begins as somebody knocks from the other side of the wall, which is followed by something freaking her out in the room. 

The trailer lets know that this one precedes the first two chapters and will take fans to the origins of "the further."

Lin Shaye who plays Elise and Specs and Tucker are also seen in the clip.

The first two films in the Insidious franchise were helmed by the writer-director team of Leigh Whannell and James Wan. But as Wan had his plate full with Fast and Furious 7 for Insidious 3 Whannell took over, and has both written and directed the project.
