Well I'd say that to choose a "most Felliniesque" movie, I'd have to choose a movie by the man himself, but the problem is what one should consider "Felliniesque"? I can hardly say that onbe movie of his is more like him than another, because he obviously made both, so I'll limit the question to what is my favourite Fellini, which to me is "Amarcord", closely followed by "Prova d'Orchestra". I do not care for his late movies like "E la nave va" or "Ginger e Fred", but then again, Fellini never was my favourite Italian director, even though I recognize his genius.
