Well, it's important because it adds depth to the narrative. Since it's based on a true story, the characters and events might have actually happened. This makes the story more relatable in a way, as it's not just pure fiction. It shows the real - life struggles, dreams, and downfalls of people in the porn industry in the 70s and 80s, which is something we might not be fully aware of otherwise.
The significance is that it gives the movie a sense of authenticity. It allows the audience to peek into a real - life era and the real - life experiences of those in the adult film industry during that time. It can also serve as a form of social commentary, showing how society and the industry interacted.
The fact that 'Boogie Nights' is based on a true story is significant as it provides a window into a unique subculture. By grounding the story in reality, it enables viewers to understand the complex relationships, the power dynamics, and the evolution of the porn industry. It also humanizes the characters involved. Instead of just being fictional personas, they represent real individuals with real emotions, ambitions, and flaws. This can lead to a more empathetic viewing experience and also has the potential to start important conversations about the nature of the adult entertainment industry and its impact on society.
