This one has it all: the star-crossed lovers from different social classes—she's an heiress, he's working class. When she moves away, he writes her every day for a year, but her mother intercepts the letters and hides them away. Every day for a year—365 letters, not one response. That right there is the kind of relentless romantic determination that lands you a restraining order in the real world. (Sidebar: Most Hollywood romances are tests created for men to see whether or not they're stalkers).

But wait! The movie is told in flashback. In the present day, the man is old but with-it, while the woman suffers dementia that comes and goes. This film often leaves people in such a heightened state of amorousness that they will mistake the slightest attraction for undying love. Do your best to be slightly attractive.
