Helen Mirren as the possibly insane heir to the Winchester Rifle fortune, has built the Winchester Mansion, a 7-story maze that is forever under construction and "the most haunted house in history." Jason Clarke is a shrink I'm assuming sent in to determine her sanity. Looks like some jump scares and some decent creepy atmosphere stuff.
That looks interesting; I'm curious to see if I'll be able to suspend my disbelief, having been in it. The only thing it was haunted by was insane admission prices and low ceilings in some spots.
