Well only 3 映画 have made me cry, I don't know if they are on culture, they were great movies, very touching! :
-The Help : great movie on a part of history, but it's fictional. It's touching and was amazing!! -The Perks of being a Wallflower : WOW! About a kids who is socially awkward, but makes friends. It's amazing better than the 説明 I just said. - The Life Of Pi : about the journey one man made with a tiger named Richard Parker, beautiful but sad.
Well there's this one movie "Life In a Day" which is basically just a whole bunch of clips from all around the world taken on the same day. It has a lot of cultural things in it.
