So I just watched Texas Chainsaw 3D in anticipation of the house. A few notes.
* Not a good movie - they especially whiffed on the timeline - the heroine looks like she's early-mid 20s, but the movie takes place 40 years after the first in timeframe (as noted on the files she sees from 1973 and the tombstone they pan past that says 2013...also there weren't android cell phones with cameras and flashlights much before 2013). So either it was bad casting from an age standpoint or, if they wanted it to be like 20 years later instead of 40, they screwed up with the tombstone and cell phones.
* The movie isn't nearly as good as the original in pretty much every way except there are a couple of good kills.
* Despite all that, I think an HHN house based on Texas Chainsaw 3D will actually be better than one based on the original, because there are more sets to work with. They COULD use the burning Sawyer house from the beginning, but I doubt it. I'd speculate that you might enter through the plantation style house and through the big door with the big key. From there you'd be ushered into the wine cellar, then down the creepy corridor and eventually into the killing room with all the bodies on slabs and hooks (especially the one cut in half) and the freezer where a girl randomly pops out as set pieces. Then, you'd be taken through the graveyard (they could start you in the graveyard, but I think the graveyard at night is scarier, and then you'd be chased into the barn, where you'd possibly escape from there into the carnival. From the carnival I think we segue into the slaughterhouse for the end scene complete with the chains & chipper, pitchfork, and of course chainsaw.
Just my thoughts on this. And, for me (many of you may disagree with my take on the movie and/or the house possibilities), this could be a prime example of a movie that's not very good that has the possibility to be a really good house.
