Ti Piace Hitchcock, Dario Argento, 2005

As a boy in 1990, Giulio was chased through the woods by three women he spied on while they were practicing witchcraft. Now a young film student in Turin, he watches his neighbors in the flats across from his third-floor apartment, especially Sasha when she's naked or arguing with her mother. Giulio's girlfriend is disgusted with his voyeurism, but after a murder occurs, Giulio is convinced that two relative strangers, just as in Hitchcock and Highsmith's "Strangers in a Train," have agreed to murder each other's bete noir. He follows his suspects, ends up with an intruder and a broken foot, and may be in real danger. Is he more than a peeping Tom?
