Being a fan of Argento's work and various giallo's, I would love to see a giallo inspired house. However, it would have to be inspired by since even some of the best giallo's run into a unique problem in terms of making a haunted house...the lack of a visible killer. A lot of giallo's can portray the killer as just a pair of black gloves, mainly due to the mystery aspect so you can't tell who it is. So that's a huge problem for a haunted house if you want the killer attacking you before they're revealed. There are a few exceptions like Torso, Blood and Black Lace, Stage Fright (which BTW, I would LOVE for this to be a house.), as well as Malignant where they do have a visible and/or masked killer. But they can be a tad far and few between.
