"Earlier this year we were contacted by the estate of the Benson family who had briefly rented the infamous house on Long Island, New York. The family has since disappeared and the estate is determined to prove that the Bensons did not abscond to avoid paying their debts (as their banks and other creditors have claimed). Watch The Amityville Haunting on December 27, 2011 and decide the truth for yourself."
From this trailer it appears to be sort of a first-person shot/found footage type film. Seems sort of fun. We'll see I guess.
