The Equalizer 3 was primarily filmed in Italy, with the main locations on the Amalfi Coast in towns such as Atrani (which represented the fictional town of Altomonte), Amalfi, Maiori, Minori, and Ravello. Additional filming took place in Naples, Rome at the Cinecittà Studios, and the Santuario Santa Maria del Bando church in Atrani. Although the movie is set in the Sicilian town of Altomonte, the realistic settings were captured along the Amalfi Coast and nearby areas in Southern Italy.
