I may have to see Shutter Island. A portion of it was filmed in the abandoned state hospital in Medway, MA. I worked on a project there last year as one of the engineers for its demolition. The project ultimately got scrapped due to budget cuts, but I did inspect the place a couple times.
It is a creeeeepy place. Especially the lobotomy room. They also had rubber padded rooms, bars along the walls to shackle the inmates to, etc. The cops/fire/national guard also used the place for training exercises. So there are spent shells all over the place, kicked in doors, and blasted open doors.
I've worked in places that were hot, cold, cramped, smelly, etc. But I've never worked in such a spooky place.
