PORCILE is two stories intercut into one. Not Pasolini's best film. One story is set in the middle ages and concerns a band of renegade cannibals/thieves who are anathama to the Catholic populace. [The head of the band is the actor with the walking stick from Bunuel's BELLE DE JOUR.]
The other story concerns a rich German family and its supposedly hidden Nazi past. The son of the family - played by Jean Pierre Leaud - has strange habits involving pigs [don't get excited, you won't see anything risque].
Not a very cohesive film. The first story mentioned was to be titled ORGIA.
