A Labor of Love (1976)

Fly on the wall documentary about the making of The Last Affair (1976), which was an independent feature made in Chicago, Illinois with a stipulation mandated by its financial backers that it had to include explicit hardcore sex scenes in order to capitalize on the porno chic trend which was popular in the mid-1970's. However, the shooting of the movie doesn't go as smoothly as planned, with various unforeseen complications along the way to its completion.
