Gregorini further claimed that Shyamalan simply took her premise and put it through the "male lens," with men looking down on a woman's mental health issues and discussing the sex appeal of the nanny. Shyamalan, series creator Tony Basgallop and Apple 'negated' the experiences of Gregorini and other women involved in Emanuel (which had its roots in Gregorini's life story), according to the lawsuit.

Apple has declined to comment on the case.

Whether or not the lawsuit succeeds is difficult to say. These kinds of disputes certainly aren't new, including to Shyamalan -- Simon & Schuster raised concerns about his movie The Village after noticing similarities to Margaret Peterson Haddix's youth-oriented book Running Out of Time, although it never led to legal action. Gregorini may have to show that the plot similarities are too close to be coincidental.
