Are there any mansions in Newport that people don't say are haunted? Belcourt Castle is another one that definitely promotes itself that way. And, of course, there's also our own beloved Seaview Terrace...
Sounds like a bunch of films we might want to avoid. Though that being said, very few horror films actually scare me. I would actually recommend 1994's Wolf because of its approach and because Michelle Pfieffer stars in it. But as I've posted before, I'd also recommend 2010's The Wolfman. I haven't actually seen any of the others...
