The depiction of family incest in cinema dates back to the early 20th century. One of the earliest examples is the 1927 film "The Fall of the House of Usher," directed by Jean Epstein, which loosely adapts Edgar Allan Poe's short story about a man's descent into madness, triggered by an unnatural relationship with his sister.
