Can't think of a sadder movie ending than this one
I won't give away the ending, but, my God, have you ever seen a movie with a sadder ending? If, like me, you really got into the story and cared about the characters, then the ending will stick with you and haunt you for a good while. That final scene with Kirk Douglas was sad and haunting like no other movie I can remember, to be sure.
