IFC Original Documentary by Kirby Dick 'This Film is Not Yet Rated' Investigates Hollywood's Best-kept Secret: the MPAA Film Ratings System and its Impact on American Culture. The MPAA screened the documentary and gave it an NC-17 rating—obliterating its potential to be shown in most theaters—for "some graphic sexual content." IFC will show the film uncut, uncensored and commercial-free next year.
