Tear Jerker / Cyrano de Bergerac
The letter scene in the convent. Between the letter itself, and Roxanne's reaction when she realizes that he couldn't possibly be reading it, that he knows it by heart even though he's supposedly never seen it before....it's a full-box-of-kleenex scene. Any production, any translation. It doesn't matter.
