Dermot Mulroney Joins 'Insidious Chapter 3;' Filming Starts In July

They story of the Lambert family concluded in Insidious Chapter 2, but the ending of that film teased a whole new world. What we saw there will expand in Insidious Chapter 3, written and directed by series co-creator Leigh Whannell. The new sequel is currently scheduled for release April 3, 2015.

That's pretty close, so casting has begun leading into a July start date. Dermot Mulroney is the first addition as the star of the film. Read more below.

Whannell announced the Insidious 3 casting on his Twitter account. What he didn't announce is who exactly the actor, best known for My Best Friend's Wedding, Zodiac, and The Grey, will play. The second film ended with a tease featuring the ghost hunter supporting characters of the first two movies visiting a new family. That family didn't have Mulroney as a member, so maybe he's the father of yet another family who finds themselves haunted, or with some connection to The Further.

I talked to Whannell, and director James Wan, about a sequel when Chapter 2 came out. Wan said the following:

I will say the expansion on this world that we've created [teases at a sequel]. I think if you're a horror fan you would know that the continuing aspect of potential future films is that we could create a potentially rich horror world, a very rich horror world that we can pull so many stories from.

With filming set to start in just a few weeks, expect some more casting in the coming days and more info on just how the world will be expanded.
