Margot Kidder and Jennifer Salt were roommates in Southern California in the early 1970s while they were struggling performers. They held parties for their friends and neighbors who included Paul Schrader, Blythe Danner, Bruce Paltrow and Brian De Palma. One year at Christmas, Kidder and Salt opened separate boxes under their Christmas tree and each one contained the script to this film. This project was De Palma's gift to them.
