Following the previews, rather than seeing the opening to Pixar's latest animated film, moviegoers were treated to images of children being tied up and murdered, Jazmyn Moore, one of the parents at the theater, told Journal-News . Moore says after being terrified by the opening sights and sounds of Insidious: Chapter 3, the children were all scooped up and rushed out of the theater.The mishap was the result of a simple mix-up by an employee in the projection booth, according to the theater's manager.Attendees were given a free movie pass in addition to a free upgrade to a 3D showing of Inside Out. However, Moore says the reimbursement hasn't helped ease her children's fears. "I got our money back but the damage is already done… my children are terrified and keep asking questions."
