Dans Ma Peau/In My Skin

If any of you have any inclination whatsoever to see this, here's my recommendation that you do so.

The film is an exploration of a woman's relationship with her body through obsessive self-harm that's triggered by her gashing her leg open at a party. Written by, directed by, starring, Marina de Van.
You gotta take a look at a few reviews, and if you sympathise with (say) the IMDb reviewer who berates it for not giving the protagonist some motivation then maybe it's not for you. The film doesn't particularly try to offer excuses. I walked out of it feeling that someone should be able to tell from looking at me that I'd seen it. Not a feeling I remember getting from a film in a long time. To an extent it falls into similar space as things like Trouble Every Day, maybe Process, maybe Tetsuo. Very intense personal explorations of self. Or something, getting all pretentious & anyway stop laughing it's not sick. Just there were points in this film where a cringe-inducing act of bloody autophagy is simultaneously clearly a loving, even erotic, act of self-exploration. Which is just difficult to watch without being kicked into a different headspace.
So whatever, there's material in here that — if you can stomach it — you might find challenging and interesting in a way that most modern cinema just isn't. Rare stuff.
