I can't believe no one else has noticed this!!!
Pasolini sometimes split his films into halves like there was to be an intermission.
At the start of the second half of Porcile, a guy is playing a recorder-like instrument at the top of a bell-tower and the annoyingly cheerful Pasolini regular Ninetto Davoli is dancing away to the music.
A group of people then gather at a big house, Davoli being one of them.
What amazes me is that no one seems to have noticed that the big house is the same one that Coppola used in each of the Godfather films!!
In the first film, it’s where Michael Corleone (Pacino) stays when is in hiding in Sicily, in Part II Vito (De Niro) has an al fresco meal there and gives gifts to his friends and Michael returns there in Part III.
Coppola used Franco Citti (another Pasolini regular) in Part I and III so he may have used this location as a reference to Pasolini although he makes no mention of it in The Godfather DVD audio commentaries.
Perhaps it was just a coincidence that the same place was used but it is DEFINITELY the same house.
I've tried to add this to the trivia sections of both Porcile and The Godfather but the IMDb hasn't accepted it. Clearly not many people have seen both films and been able to verify this.
