La Strada by Fellini, 3rd behind Citizen Kane and Casablanca
La Strada as well as Fellini’s 8 1/2, which is surely the most thematically complex and photographically masterful films he ever made.
I am biased - I have seen all of the “great films” but 8 1/2 still stands out as a singular masterpiece.
By the way... Who directed Casablanca? Anyone know without googling? Anyone? ...Anyone?
