It was the biggest and most expensive adult movie made at the time of its release.
The scene at the beach originally was to have the actors roll around the sand to recreate the classic scene from From Here to Eternity (1953). However, the actors were worried that they might get too much sand in their eyes and mouths, so that was dropped.
The last scene between Jenna Jameson and Vince Vouyer was shot in a beach in Hawaii. The section of the beach where the scene was shot was surrounded by a large curtain to so it wouldn't be visible to the general public, but shooting nevertheless had to be stopped several times because of people still managing to sneak a peek.
