If you've seen the previews for Guillermo del Toro's latest horror film "Mama," you know you'll probably never call your mother this endearing derivative again without the creepy child-whispered version crossing your mind. You also know that the scrambly movements of a wraith-like character in unreal bodily positions makes it appearance in this film as well.

In fact, characters such as this, usually portrayed as a female, have been cropping up in horror movies for the last few years. The video for a motion test from "Mama" with actor Javier Botet gives you an inside look at their making -- if you can handle it.

The male actor providing the movements for the ghostly character, from which the film gets its name, is effective in part due to his extremely thin frame, which is the result of Marfan syndrome, according to io9.

The NIH describes Marfan syndrome as a genetic disorder that prevents the building of connective tissue and also causes very lengthy long bones, like legs and arms.
