The trials and tribulations of three middle-class families who all live in the same apartment building in Rome play out across the years in the latest from Nanni Moretti, his first literary adaptation (from a novel by Israeli author Eshkol Nevo). We follow: judges Dora (Margherita Buy) and Vittorio (played by Moretti) and their teenage son, who has recently caused a drunken car accident; a very pregnant Monica (Alba Rohrwacher) and her oft-absent husband Giorgio (Adriano Giannini); and Sara (Elena Lietti) and Lucio (Riccardo Scamarcio), who enter into conflict with their elderly neighbors when Lucio suspects one of them, Renato (the late Paolo Graziosi), of having abused Lucio and Sara’s 7-year-old daughter. The absorbing Three Floors chronicles its characters as they push forward in spite of the misfortunes, mistakes and disappointments that pile up all around them, with Moretti’s powerhouse cast conjuring a world within a condominium.
