The list author says: "When I search for "incest movies" I typically get back films like "Back to the Future" or "Empire Strikes Back" - but this list, while not exhaustive, have incest as a major plot element."
"Adolescent brother / sister - pretty good movie about 2 high school siblings in Manhatten dealing with older sister's suicide, mother's alcoholism. I've only seen this available on Amazon Instant Video."
"AKA Carne de tu Carne (Flesh of Your Flesh) Adolescent brother / sister - strange movie thats starts off "conventionally" as sister returns to south america and sees her estranged brother but by the end there are ghosts, stealing babies, etc. - a political allegory apparently."
"Father / daughter - kind of a dark, Freaky Friday as mother's consciousness gets transferred to daughter's body after a fatal car accident - mother (in daughter's body)attempts physical relationship - but no "real" incest."
"Brother / sister - this 2014 U.S. TV version is better and closer to the famous novel then the 1987 theatrical version. Not bad. German TV still tops with shows like "Der Kuss Meiner Schwester" and "Riekes Liebe"."
