Rarely credited, Rodolfo was nevertheless entrusted with many speaking roles, and by the 1970s, he was being awarded some more significant credited roles. Indeed, his two most famous and memorable roles are the ones which he interpreted towards the very end of his long career: as the ill-fated archbishop in the comedy classic Il secondo tragico Fantozzi (1976), and as Jill Clayburgh's old opera maestro in Bertolucci's La luna (1979).
