From Jorge Molina’s article for Queerty:
Pink Narcissus is not a long film; it is barely over an hour long. It was directed by queer visual artist and photographer James Bidgood, although he is cited as “Anonymous” in the credits.
The identity of the director was unknown for many years since it was released without Bidgood’s consent (Andy Warhol was even rumored to be behind it because of its distinctive style). And it has since become one of the most striking and memorable examples of queer experimental film.
In a very general sense, the film follows an unnamed young male prostitute who, in between visits of several clients and his keeper, imagines himself in various erotic scenarios: as a matador battling a leather daddy in a motorcycle, as a belly dancer performing for a gazing sultan, and as a Roman slave boy being condemned by the Emperor.
