the most sad movie is "veer zara" movie ...this movie songs is very very beautiful and romantic... you see this movie you blubber...
It's an animation. "Grave of the Fireflies". I have cried for 3 days after watching it and i never thought that a cartoon can be so touchy.
I can remember the end of Click making me cry, and the end of Two Brothers. The one that made me cry most was All Dogs Go To Heaven.
