Indie documentary filmmaker Kirby Dick produces a muckracking, highly critical movie about the opacity and the inequity of the ratings system propagated by the Motion Picture Association of America—which includes revealing the highly guarded identities of the Ratings Board members—and then submits the film to the MPAA to get rated. After the initial cut gets rated NC-17 for "depicting examples of what will get a film rated NC-17", Dick adds the footage of the rating and appeals process to the final version of the film. Which is not now and never will be rated. AWESOME.
And then he manages to out the identities of the appeals panel who apparently put him through a Kangaroo Court.
