http://www.crispinglover.com/WIIPreview.html "Being the adventures of a young man whose principle interests are snails, salt, a pipe, and how to get home. As tormented by an hubristic, racist inner psyche."
Crispin Hellion Glover's What Is It? is a "bewildering, unnerving, surreal, blackly comic film" staring a cast entirely comprised of people with Down's Syndrome.
As listed in one IMDb user's comments, the viewer is able to see a scene featuring "a naked woman in a monkey mask masturbating a 60-year-old man who has cerebral palsy while he reclines naked on a large sea shell."
Think of me as you will but I have to see this even if it is considered exploitative. Where else am I going to see Shirly Temple depicted as the antichrist ordering the mentally challenged to kill snails?
