The earliest iterations of this genre were largely celebratory. Studio-sanctioned "making-of" featurettes served as marketing tools to build mystique around movie stars and legendary directors. However, the rise of independent filmmaking in the late 20th century shifted the perspective from adoring to analytical.
In the early days of home video, the "making-of" featurette was born. These were short, sanitized promotional pieces packaged as DVD extras, largely consisting of actors praising their directors and producers celebrating smooth shoots. They were infomercials disguised as documentaries.
The women were recruited through advertisements that made no mention of pornography. They were flown to San Diego, where they were subject to a web of lies and intense pressure. Many victims testified that they were plied with alcohol and marijuana and then rushed into signing contracts they were not allowed to read fully.
You no longer need a Netflix or HBO deal to launch a successful entertainment doc.
Furthermore, the "Faux Documentary" is rising. Mockumentaries like The Rehearsal (HBO) blur the line between reality and performance, critiquing the industry even as they participate in it.
