It was this film as well as "Behind the Green Door " and "Deep Throat" that led some mainstream critics, Roger Ebert included, to begin to take porno films seriously. It was a movement, speared mainly by Marylin Chambers, that was known as "porno chic." Lines would form at porno movie houses and would occasionally include celebrities. Openings mights might include spotlights, the stars emerging from limos, etc. However, the introduction of videotape seems to have ended it all (well portrayed in "Boogie Nights"). The adult film industry has for the most part gone downhill since this so-called "golden age." The DP scene so daringly depicted in the film is commonplace today.
