Most of the filming, including the memorable scene of a statue of the Madonna emerging from the sea in a local procession, occurred on the islands of Procida and Ischia. While the thrilling plot surrounds the sinister murder of a young man off the coast of Italy, it is the jaw-dropping cinematography that immediately captures the imagination. This film adaptation of Patricia Highsmith’s novel by the same name is set in the fictional Italian town of Mongibello, modeled on Positano.
