Puzzling. It's everywhere. Adultempire, Hotmovies, etc. Fifteen actresses listed. Fourteen scenes. I even looked at Fashion Models Gone Bad # 2 and # 3. Nothing in those films either. Ashton Moore is listed in the credits but just not in the film. At data18, they have fifteen scenes. They have Harley Davis' name listed twice.
Some differences between the iafd, adultempire, hotmovies, and data18 : Andrea Spinks is credited at data18 as "Pixie" (matches the iafd), Caz McKenzie is listed as "Giselle" at data18 (matches adultempire and hotmovies) - the iafd lists Avy Lee Roth also as "Pixie" - she's not in the film either. Both adultempire and hotmovies do not credit Andrea Spinks nor Pixie. Her scene is there at both websites. Though it is blank in the area where the actress' name would be.
I doubt it. It's a mystery. Although it's not like Kevin Costner in The Big Chill. His two scenes (one was the suicide scene) were edited out of the final film in post production.
