Marcello Mio has inherent appeal for cinephiles of nepo-baby lineages. 

This new movie casts Chiara Mastroianni — daughter of Marcello Mastroianni and Catherine Deneuve— to play a version of herself who, to cope with her nepo-baby struggles, decides to live a sustained, performance-art bit in which she pretends to be her father.

All day.

Every day.

All while staging ample references to the oeuvres of her rents.

Oh, and did I mention that Catherine Freaking Deneuve freaking plays herself, as do a coterie of familiars from Chiara’s personal and professional (is there a difference for nepo-babies?) past. 

And yet, Chiara herself didn’t actually write the screenplay, which might be why the movie doesn’t try to pass itself off as a documentary. Rather, it roots itself firmly as a fictional representation of her real existence.
