Whether you consider Stanley Kubrick’s film Eyes Wide Shut to be a flawed, misunderstood masterpiece or a pretentious, leaden exploration of… something, it does reveal a lot of sexual history.
The centrepiece of the film is a sequence in which the lead disguises himself and crashes an exclusive orgy for the ultra-wealthy. He wanders around the mansion, witnessing what is probably the most boring and unerotic orgy ever committed to film.
