I don't think an NC-17 rating is the kiss of death. Nor do I think that, in the hands of the right filmmakers, studios have a preconceived notion to pass on NC-17 material. Steve Tisch
NC-17 means that you get it in like 3 theaters. They won't run the spots on MTV, won't run the advertising. It's the kiss of death so there was really no other choice. Rob Zombie
In response, the MPAA eventually agreed in 1990 to a new NC-17 rating that would be trademarked, and could only be applied by the MPAA itself. Source: Internet
I hear they are having some problems getting an R rating from an NC-17 rating, which is never good.. Source: Internet
