Netflix has set an Oct. 22 drop date and launched a new teaser/trailer for its hotly anticipated show “The Monster of Florence” from Italian genre specialist Stefano Sollima about a string of sex-related murders that took place outside Florence from the late 1960s to the mid-1980s.

The four-episode limited series, which was shot largely on location, reunites Sollima with writer Leonardo Fasoli and ace Italian cinematographer Paolo Carnera, both of whom Sollima worked with on “Gomorrah” and cocaine trafficking drama “ZeroZeroZero.”

Sollima, known for the gritty TV hit “Gomorrah” and movies “Sicario: Day of the Soldado” and “Without Remorse,” spent more than a year researching the still unsolved case of “The Monster” (“Il Mostro,” in Italian), the moniker given to the alleged serial killer who committed eight double murders, preying on couples parked in cars in secluded places around Florence. “The Monster” always used the same weapon, a 22 caliber Beretta.

Sollima was in the Venice competition in 2023 with gritty crime feature “Adagio.” He could be headed back to the Lido with “Monster of Florence.”

The cold case marks one of the longest investigations into the most brutal serial killings in Italian history.

Netflix has also announced the show’s Italian cast comprising Marco Bullitta, Valentino Mannias, Francesca Olia, Liliana Bottone, Giacomo Fadda, Antonio Tintis and Giordano Mannu.

“The Monster of Florence,” which was created by Fasoli and Sollima and produced by Fremantle-owned The Apartment and Sollima’s AlterEgo shingle. The show’s producers are Lorenzo Mieli, Sollima and Gina Gardini.
