The Silence of the Hams aka Il Silenzio dei Prosciutti (1994) is a comedy movie directed and written by Ezio Greggio and features an image-by-image parody of Thriller. It is a parody of many horror movies, notably The Silence of the Lambs and Psycho. It can be considered a precursor to Scary Movie, although it didn't achieve the same level of publicity or cult status.
The comedy in this parody, aside from making references to other movies of the era, is largely driven by tightly packed puns, gags, continuity errors and video splicing.
