The Duke of Burgundy (IMDB) is a 2014 drama film written and directed by Peter Strickland, and starring Chiara D’Anna as Evelyn and Sidse Babett Knudsen as Cynthia. Shot in the UK and Hungary.
One of the oldest cliches in BDSM is “the submissive has all the power”. This is not always true, nor is it necessarily a good thing, as the life of Leopold von Sacher-Masoch demonstrated. Submissives and masochists can be abusive, as shown by The Duke of Burgundy.
Somewhere in Europe, sometime in the mid-20th century, two women play out elaborate sadomasochistic scenarios. Evelyn, playing the meek maid, comes to the house of Cynthia, playing the haughty mistress. Evelyn’s duties of cleaning and laundry are, inevitably, unsatisfactory, which results in punishment. Cynthia drags Evelyn to the bathroom, closes the door on the camera, and urinates on her.
Obviously, the MPAA would not give a film could give a film with an explicit golden showers scene an R-rating or even an NC-17 rating. (IMDB says it doesn’t have a rating in the USA.)
A few days later, they do it all over again. It’s a bit reminiscent of Secretary or the Munby-Cullwick relationship, a private world between two people in which mundane activities are elevated to erotic rituals.
