Paolo Sorrentino’s latest film “The Hand of God” begins with a bird’s-eye view of Naples, his hometown, at dawn, with a lone vintage car traveling along a seafront road while the rest of the city uncharacteristically sleeps. As a backdrop to this autobiographical coming-of-age story, Naples is at turns fantastical and decadent, sunny and unpredictable, comfortably familiar and ultimately confining.

Off camera, it is even more. In the 20 years since Sorrentino last made a film here — his directorial debut “One Man Up” — the city has also matured as a center of movie making in Italy. These days, film and television crews are a common sight on Neapolitan streets, both downtown but also in its rougher hinterlands. These productions have nurtured the formation of a local industry, including actors, specialized technicians and cinematographers.
