Cat People
This David Bowie song is really called Cat People but most people would probably remember it as Putting Out The Fire with Gasoline. It was written as the theme song for the 1982 horror movie Cat People, a remake of a 1942 movie.
It has a female lead named Irena Gallier, played by Nastassja Kinski. She is a virginal young adult looking to reunite with her "long lost brother" Paul.
Unbeknownst to her, she's a werecat and so is Paul. They transform into black panthers if they have sex, which she doesn't know because she has never had sex.
It can be avoided by mating with another werecat, typically one's own sibling, and Paul tells her their parents were siblings.
They revert to human form again only if they kill a human. Paul is a serial killer with a basement full of bones and he begs his sister to "save" him from this horrific nightmare existence and agree to a committed incestuous relationship with him. She declines.
She ultimately loses her virginity and doesn't kill her lover, a zookeeper, because she actually loves him. Wikipedia indicates she does kill someone else to resume human form and asks him to kill her.
Instead, they make love again and the movie ends with him hand feeding a docile black panther.
I like the film for having a female lead at all and for clearly delineating two characters with the same exact curse and very different outcomes because one has ethics and the other only has excuses.
Paul chooses to be a serial killer and wishes to pressure Irena into an incestuous relationship with a monstrous man she doesn't really know and hadn't seen in years to put a stop to the killing and tells her only she can stop him from killing again to try to make her agree to this revolting relationship.
She ultimately chooses to permanently remain a cat rather than choose between incest or being a serial killer.
Having been the victim of incest, I like the film and found it extremely cathartic for making it clear that no matter how bad the family curse is, you still have a choice and not everyone will do what's "convenient" for them or what allows them to have the most seemingly "normal" life and tell themselves these atrocities are something they can't control or stop or avoid.
For some people, I imagine it would be a hard film to see. For me, it was cathartic, freeing, empowering and affirming.
As I say elsewhere, if the only solution you know is putting out the fire with gasoline, you're better off doing nothing and watching it burn.
