You're right to be dubious about the AFI 100 (Which excluded Sunrise) and to include many of the films which have appeared in international polls. All of your list belong in a top 100. Having studied a huge number of polls in a range of countries, including Russia, Germany, Romania, Portugal, Belgium, as well as publications like Time Out, Sight and Sound (top 100 not just top 10)and Village Voice, i'm surprised you had Battleship Potemkin outside the 25.Greed, Balthazar and L'Avventura were probably the most questionable.A dificulty is trying to combine popular and critical opinion;Casablanca, Some Like it Hot, Singin' in the Rain  The Godfather/Godfather 2 and It's a Wonderful Life do well in both sections.It's not clear that City Lights is more highly rated worldwide than The Gold Rush.I'm delighted that Sansho the Bailiff is doing so well in ForeignFilms' own poll-Mizoguchi should be much better known in English-speaking countries.I conducted a poll for a specialist world cinema company here in the U.K; THE TOP 20 was:Seven Samurai,The Third Man,Les Enfants du Paradis,Blade Runner, Casablanca, Cinema Paradiso, 2001:A Space Odyssey,Some Like it Hot,La Regle du Jeu,Brief Encounter,Three Colours Red,The Searchers, Les 400 Coups,Vertigo,The Seventh Seal,Battleship Potemkin,A Matter of Life and Death,Citizen Kane, La Grande Illusion, Double Indemnity.
