I’m calling bullshit on this, too. The US has fairly strict laws about what you’re allowed to do with human remains, regardless of how old they are and whether or not their previous owner said you could. There are many places in the US where it against the law even to scatter cremains. What happens to a body that’s been donated can be sort of up in the air- you may end up in a med school’s anatomy lab, you may end up a crash test dummy. But every industry that even thinks about using actual human remains must get express permission from the state in which they are operating, or from the US gov’t if they plan to cross state lines. They must provide proof of what they intend to do, and any regulatory agency can at any time deny them this permission for a variety of reasons, most of which have to do with health codes. I seriously doubt that any of this was real. And the anecdote about the shaman’s exorcism is a little too much for me. My guess is it’s some bit of publicity drummed up for the movie.
Also, I can’t see the link at the moment, so does anyone know if these skeletons are actual human remains and not plaster or plastic? Most schools use artificial models because they hold up much better, but they’re not necessarily cheap- quite a bit of work goes into making a realistic one, and seeing how it’s such a specialized market, they’ll be charging higher prices. But a movie studio could certainly afford some, or even make their own that would be much easier to deal with, both legally and practically, than actual human remains.
It just doesn’t make sense, and it smells like a publicity sham.
