Alternate Endings and deleted footage not included in Blu ray
I was expecting more footage than what we got in the Blu ray.
Paranormal Activity 2 trailers
Chandelier swaying, furniture being thrown across foyer, Toby behind Ali on couch, Hunter rising up in crib, Daniel and Martine burning photo of Katie with religious stuff on table, Katie standing by Hunter's crib in the doorway with Hunter in mirror but not in the crib.
And apparently there were multiple endings filmed.
Paranormal Activity 3 trailers
Kristi knocking on mirror then Toby knocks back, Kristi throwing water at Toby, Psychic opening 'door' in Katie and Kristi's room to see it completely trashed and a drawing of a stick figure with red eyes, and the words 'HUNTER' scribbled backwards, Psychic getting his head slammed on table then pulled away, Julie dragged away to bedroom, House fire.
Ghost Dimension
Children walking towards camera with 'spirits' around them, possibly related to The Marked Ones.
They were done so well, but they weren't even included as Extras.
