I don't really think "Boogie Nights" was designed to be about "real" people, but rather "inspired by"... Which REALLY leaves the flood gates open for anything and everything to come down the pike.... My guess is P.T. Anderson took many of the things he "heard" or read about and just lumped it all together.
Personally, I liked the movie "Rated X" about the rise and fall of Jim & Artie Mitchell. From what I gather, it was pretty spot on correct".
In any event, I do hope Jenna's biopic works out well for her. Personally, I wouldn't try to make the movie as some high-end, glossy, Hollyweird feature.... I seriously think that will kill what it "could" be (contrary to popular belief... a lump of shit squeezed out of a billionaire's asshole is still just a lump of shit). I would personally take it down the independent road and fill it with fresh new faces.
