At the True/False documentary film festival in Columbia MO today, I saw a doc called
Tickled. It begins as a New Zealand journalist's exploration of the funny world of "competitive endurance tickling" and evolve into something a bit more...well, let's say "A Dirty World"-esque, or possibly "Unknown Armies" material. It ended up being not so much about the tickle fetish community, but more about one very rich guy with a destroying-people's-lives-with-blackmail fetish.
The filmmaker was on hand for Q&A. Yesterday he got served with legal papers on the sidewalk outside the theater. Also the police threw two people out of the screening for videotaping it, possibly private investigators.
At Sundance it got bought by HBO and Magnolia Pictures, so I suspect it will be widely available soon.
