I find myself going back to films like THE FALCONS by Gaal or TEOREMA by Pasolini. Poetic masterpieces both of them. For real human comedy with a social twist, the films of Milos Forman are still relevant today. Darker comedy [with political overtones] are to be best sampled in Fassbinder's films. The most influential post-war director/craftsman was Godard, of course.
