As far as fiction, almost all of my favorite films involve someone who would arguably have mental illness, or at the very least a personality disorder.

Blue Velvet for example, is my favorite film. Or, I mean, it was rife with sexual disorders. And sociopathy. Certainly there was mental illness, if it were to be analyzed, peppered in there. It shocked me at the time.

But most shocking video? I'd have to really think on that. I'll get back to you on that one. I could cheat and say the Luka Magnotta video, but the consensus is he had no mental illness and merely a personality disorder.

The obsessed Bjork fan video was pretty disturbing at the time. That was a very clear case of mental illness. Documented in video diary style.

I can say the latest sort of shocking video involving a mental/physical illness I've seen though. It'd be a YouTube clip of Shelley Duvall on Dr. Phil's show (can't stand Dr. Phil). Not shocking in as much as seeing the symptoms of schizophrenia, but shocking in the sense of seeing how vastly different she was from her former years as a result. Deeply in the throes of it. Seeing the dramatic change was fairly surprising, and alternately sad.
