No interest in defending porn (or in porn in general) just took slight exception to the idea that a film like Boogie Nights signified pornographic strains in popular entertainment. I love that film and it is not pornographic.
I can appreciate that you loved the movie. I liked the movie and have not stated that is is a pornographic film. However, the initial post from SeekAndFind mentioned the merging of porn into the mainstream cinema and Boogie Nights does that. For example- Burt Reynolds researched his role by hanging around porn sets. Paul Thomas Anderson adapted dialog from actual porn movies so that the porn dialog in his movie would seem authentic. Porn actresses Nina Hartley and Veronica Hart had roles in Boogie Nights- Nina was Little Bill's wife and Veronica played a judge. Veronica went on to act in other mainstream movies including another Paul Thomas Anderson film, Magnolia (also a movie I enjoyed).
