A few years ago I needed to make a bunch of bodies for a meat-locker type room. I came up with a method for making super-cheap, durable, yet fairly realistic body forms. The premise for the room was the guests will walk thru a room that is literally filled with hanging bodies. The room is lit only with a strobe light, creating confusion as the bodies swing when the guests travel thru the room. Because of the limited line of site, there are many places for actors to hide. The overall effect was a stunning room with lots of scare factor for very little cash.
