Depending on the material or the genre, different filmmakers cast an eye on the business that can be critical, judgmental, or simply curious. Sometimes that means the whole movie follows a character who works in the industry sometimes the world of porn is simply adjacent to the film's main plot, providing a backdrop to a sweaty crime thriller, a creepy slasher bloodbath, or a slick buddy comedy. Instead, these are movies that tell stories about the business of filming, marketing, and selling sexually explicit material. Fair warning: While many of the movies on this list contain graphic sex scenes and quite a bit of nudity, they don't exactly qualify as pornography.
