"Back in 1990, the MPAA (The Motion Picture Association of America) replaced the X rating with NC-17 because X had become synonymous with pornography. Unfortunately, even when changed to NC-17, the stigma of the rating still lingered, and made almost any film with an NC-17 impossible to place in theaters. Numerous high-profile movies like American Psycho, SAW, Boys Don't Cry, and Goodfellas all had to alter or cut scenes in order to get their NC-17 rating changed to an R. Some films, however, threw caution to the wind, stood up against censorship, and refused to change. These films went on to be released with an NC-17 rating or were released as Unrated."
