Strangest part I always thought was, there was a movie I saw a few years back, I don't know what it was, what channel it was on, it kind of looked like a Lifetime mystery or something, and it was done either in the 80s or 90s and the front room with the two front doors in it looked EXACTLY like the front room in this movie and that's why I wondered whether it was a real house or not because that's kind of a hard thing for almost an exact room of that type to appear in two movies about 40 or 50 years apart just by coincidence.

It definitely looked like a miniature to me, but I agree it was extremely freaky.
