INEXORABLE, released in France last week and currently in competition at the Toronto International Film Festival, follows on its heels, and is one of the most heavily reviewed films of in the 2021 festival lineup. It stacks up as an erotic thriller featuring another troubled young woman who insinuates herself into the life of a successful writer and his family. The comparisons in the linked reviews below range from LEAVE HER TO HEAVEN to much more recent films with much more dubious pedigrees (THE HAND THAT ROCKS THE CRADLE and STOKER).
The Italian review (fifth in the list) is particularly acute in isolating common details that occur across du Welz's films; only the final review is an outright pamThe sixth review, from Variety, is by our old pal Dennis Harvey, a long-time reviewer of our French noir festivals: he likens the film to a 70s giallo.
One review speculated that Netflix might well pick up INEXORABLE, though I'm not aware of too many first-run foreign films (in need of subtitles) crashing into their rotation. Nevertheless, it's a title to jot down as being worthy of a look if/when it becomes readily available for viewing in the US. (And Dennis Harvey suggests that the film will need subtitles in the US for another reason: a scroll of semi-squeamish backstory notes that are revealed as part of the closing credits.)
