Not so strangers. Patricia Highsmith according to Alfred Hitchcock

In this work I propose to analyze how the cinematographic transposition of Strangers on a train has changed the suffocating amoral world of Patricia Highsmith in a typical Hitchcockian frantic suspense story, blurring the darkest edges of the characters and situations of the original novel. The aim is not to determine whether the film is more , better or worse than the text –an unproductive enterprise– but to reflect on the operations made by the director to seize the literary work and make of it a film that responds to his own vision of the world and of cinema.
