"You need an R rating because without one, you can't advertise and the film won't get shown"

This quote by Tobe Hooper is referring to the value of having an R score for a movie. An R rating is a category offered to a film by the Motion Picture Association of America (MPAA) that suggests the movie consists of content that may be inappropriate for kids under the age of 17. Without an R ranking, a film can not be advertised and will not be displayed in theaters. This is since the MPAA does not enable films with an R rating to be marketed on tv or radio, and numerous theaters will disappoint films with an R score. For that reason, having an R score is important for a movie to be seen by a large audience. Hooper's quote stresses the significance of having an R ranking for a movie in order for it to be successful.
