Thanx for finding me on Flixter. On Truffaut: yes I love him. I rate his Doinel cycle as the best of his work, les 400 coups is the first one of the Doinel movies but I would recommend to certainly check out Baisers Volés & Domicile Conjugal. His only English spoken movie, Fahrenheit 451 (based on a science fiction novel of Ray Bradbury) is a real cult movie and if U can find it be sure to watch it. Truffaut never really made a bad movie although I rate L'Enfant Sauvage and L'Amour en fuite is his least work, but it's still okay. If U like Truffaut, then also check out 2 other French Nouvelle Vague directors: Louis Malle (but not Zazie dans le Métro, I really dislike that one, it seems like it was made on acid) and Claude Chabrol, I also love them.
Looking at your favorites, I see that U were lucky to be able to see Ladri di Bicicletta & Roma Citta Aperta: neorealism classics, I still have to see those. Oh, and I also adore Billy Wilder's Sunset Boulevard, in my book by far Wilder's best (far better than Some like it hot, which I find enjoyable but a bit overrated, it's basically just a screwball comedy) and one of the better films of the '50s. Anyway, U've got great taste and yes our taste is very similar.
