Okay let's be honest, which movies made you cry?
Star Trek II, when Spock died. I spent a lot of growing-up years with Spock and to see him die just ate me up. I bawled like Captain Kirk...
King Kong (the original, not the fluffy, irrelevant Jackson remake), when King Kong died from his fall off the Empire State building. Man, that big ape was such a tragic character.
The Hunchback of Notre Dame (1939, not that saccharine, silly and very lame cartoon remake), when Esmerelda leaves and Quasimodo is alone, unloved. He rests his head against a gargoyle and pines, "Why was I not made of stone like thee?" Very moving, but I truly loved the book a lot more. (No one can get choked up over cartoon characters, anyway... that would be weird...)
Gandhi, when Godse shoots him, and all the hopes he nurtured are shattered. Really powerful moment in film. Even more so than the death of Lawrence at the beginning of Lawrence of Arabia.
M*A*S*H - okay not a movie, but a TV series. When Radar announced the death of Henry Blake. And again when the war ends (the finale).
Away From Her - a couple of times, but especially when Gordon Pinsent realizes his wife, suffering from Alzheimer's, no longer loves him, and has forgotten what they mean together. A real tear jerker.
