Today, Wondercon fans were treated to the first clip from Insidious Chapter 3, the third movie in the horror trilogy from writer/director Leigh Whannell, and cast members Dermot Mulroney, Stefanie Scott, Angus Sampson, Leigh Whannell and Lin Shaye. In the clip Lin Shaye's character, Elise Rainier, warns, "if you call out to one of the dead....all of them can hear you." Watch the all-new footage below.

In addition to the new clip, Focus Features has also unleashed a brand new poster for the film, which you can see below. A distressed Stefanie Scott embedded within, the poster claims "This Is How You Die."

The newest chapter in the terrifying horror series is written and directed by franchise co-creator Leigh Whannell. This chilling prequel, set before the haunting of the Lambert family, reveals how gifted psychic Elise Rainier (Lin Shaye) reluctantly agrees to use her ability to contact the dead in order to help a teenage girl (Stefanie Scott) who has been targeted by a dangerous supernatural entity.
