Ok here' s an obscure one.  
  Bjork and David Morse in 
Dancer in the Dark.     
  I apologize in advance for the length of my explanation, but since I' m pretty sure NO ONE saw this movie, I think it' s needed. Bear with me.    
  Selma(Bjork) plays an immigrant who is slowly losing her sight due to a hereditary condition. Her son has the same condition, but at his young age, a medical procedure could prevent blindness. Selma has been working ridiulous hours in order to save enough money to get the surgery for him, and she' s been keeping that money in a small tin in her cupboard.     
  David Morse plays Selma' s friend who has thusfar helped Selma survive on her meager salary. She lives in a trailer in his back yard, etc. However, David is in financial trouble and is rapidly becoming unable to support his wife. He' s been keeping his troubles a secret from his wife by using his savings, but now his savings are almost gone.    
  Faced with the prospect of telling his wife he' s broke, David decides to steal the money Selma has saved. He' s also fabricated a story about Selma to force his wife to kick her out. Selma is half-blind, but she knows about David' s money problems and figures out pretty quickly who has her money.    
  The scene starts with Selma' s  discovery of the theft and ends when she kills him. 
  This scene actually made me uncomfortable in the theater. It' s like watching an actual murder.     
  Long scene, but worth it.
