La Notte, Antonioni
One of my favorite movies, Jeanne Moreau is very compelling, and Mastroianni is great as usual. A famous writer and his wife struggle with ennui, and go to a dinner party.
Les quatre cent coups, Truffaut
Also a new favorite, an adolescent boy passes by the people in his life, just barely missing them, unable to avoid trouble, and not sure about any future.
Jules et Jim, Truffaut
I like and recommend, but my least favorite Truffaut so far. Very interesting plot structure and pacing. The film progresses through a couple decades as two good friends live life, both wrestling with a crazy woman.
Stalker, Tarkovsky
Highly recommend, was pleasantly surprised myself. The stalker is a man who can lead people to a special place in the forbidden Zone, the Room, where wishes come true. He leads two men there. Fantastic looking movie, reminded me at times of Herzog style wise, although it's thematically it's own (and much deeper).
