"ANATOMY OF A MURDER could run for another three hours after the end titles, cover another three years in the life of its hero, and we should still be no nearer the truth of the case. In LA NOTTE the ‘real ending’ is knowable, but has been withheld. The picture would need to cover at most another two or three hours in its protagonists’ lives in order to resolve the ambiguities of its last sequence. In Preminger’s movie the story ends with a major issue unresolved. In Antonioni’s the story is abandoned when it has served the director’s purpose."
