I was designing some costumes for our haunt this next year and among the "throw-aways" is this stretcher. The entire costume was to be used between two guys carrying a stretcher through the waiting lines. The body parts on the stretcher are moving and there is a living half man too.
The secret is an oldie but a goody. Each man carrying this stretcher is covered in a robe. One man, pictured, is bent over laying on the stretcher. Attached to his waist and legs is a support that holds up a fake (upper half) frame. The robe is over this frame. Fake face and hands should be well visible.
There is really nothing more to say about this. Yes, there is a hole for the actor to bend through. I hope this can be used by someone out there, we are passing on it here.
