Come parli, frate? (1974)

The movie is a spoof of Alessandro Manzoni's novel 'I promessi sposi.' Don Rodrigo is a shy geek and has to be forced by his thugs to approach Lucia. Fra Cristoforo sings a rock song. In the final scene we see Agnese, Renzo, Lucia and Fra Cristoforo saluting the spectators on a boat.
