Dark House (2009)

Claire is plagued by repressed memories from her childhood when she witnessed the murder of seven children at a foster home.  Her therapist tells her the only way to recover is to face her fears by going back to the house.

In her college acting class, Walston Rey shows up and offers each student $300 to act for one night in his new haunted house attraction, which happens to be the sight of the murders.

The class of six joins the four person team who set up the house.  They are assigned roles and given a tour.  The house is rigged with two thousand laser projectors which react via an infrared sensor that can read excitement or fear.  Walston uses "the worlds most advanced hologram transmissions" to fill the house with creatures, mad scientists, zombies, killers and their victims.  So it seems odd that they want five students to play roles since the house is full of hologram creatures.  The holograms look real, appear solid, and can speak.

As is expected, something goes horribly wrong in the run through.  Mainly the spirit of the murderer takes control of the holograms.  Oh lordy, no!  It gets a little confusing at a few points due to Claire's flashbacks, but eventually that is straightened out.  There is a twist ending.  It's an average film and the hologram technology is a bit silly, but Jeffrey Combs is enjoyable as Walston Rey.
