The House
I've been working on drawing up a floorplan of the house from NotLD for a roleplaying game I plan to run for Halloween this year.
So I watched the movie, stopping and starting to try to figure out the layout.
There were a couple of interesting discoveries...
First, that the flow of the action doesn't cheat. I was able to consistently follow the characters from room to room and they stayed with the floor plan... no one enters from the wrong direction for the sake of shot composition.
Two, the house is cramped and ugly... smaller than I assumed. I've read that it was going to be demolished so the owner didn't care about the film crew tearing it up, pounding nails into the walls.
Three, best as I can tell there don't seem to be any bathrooms on the ground floor. All the doors except one (the kitchen pantry I think) are opened and accounted for. The upstairs is pretty much a mystery but I suspect there may not be any toilets n the house at all. There are sinks in the kitchen and basement and what look like some pipes running down the walls in the living/dining room... but all the plumbing seems crudely implemented.
Once I'd figured out how the rooms were arranged I was even more confident that the plan for survival I've had since I was a kid was still a good one. The stairway is in a narrow hallway with only three doors, no windows. Much easier to solidly barricade the three doors with furniture and retreat upstairs... pile more heavy furniture onto the stairway and you'd be golden. No way the ghouls are getting up there, but you've still got exits/view ports from the windows.
