I have cried at very many movie and tv scenes. Some examples:
Star Wars Episode I - when Qui-Gon and Maul die.
Star Wars Episode VI - when Vader dies.
The Fly 2 - when the dog gets deformed and is treated cruelly later on.
Titanic - when Jack dies.
Alien 3 - when Ripley dies.
I, Robot - when the robot is about to be killed.
The Bodyguard - when Rachel and the guy part.
Casualties of War - when the girl dies.
Equilibrium - when the lady dies.
Gorillas in the Mist - the ending.
Intensity - the ending.
The Last of the Mohicans - when the girl jumps.
