This is the first I've heard of WINCHESTER. I guess any publicity is good publicity for a movie like that.
The film or the house, which is better known as the Winchester Mystery House, upon which the film is loosely based, as there are also Winchester Houses in the U.K., Kentucky, Mississippi, and--yes--even in Florida.
As long as I lived in southern California, I wanted to go up to to San Jose, California, where the house was located, but, I never got there. Though, it is still on my bucket list of places to visit.
This is not the first film to deal with the subject, as in 2009 Asylum Films came up with Haunting of Winchester House, which--apparently--went straight to video, and earlier in 2002 Stephen King's TV miniseries, Rose Red, was even more loosely based on the the original House. + it has been part of Roessner's novel Vanishing Point and Powers' novel Earthquake Weather.
Though, it is said none of these can be compared with the strangeness of the house itself--with stairways that go nowhere, doors that open onto nothing, and interior windows between rooms. All built by the widow of firearm magnate William Winchester, who it is said built it this way to confuse all the ghosts of those who were killed by her husband's Winchester Rifle.
And, if I should live so long, I'm going to get to see it.
