I've seen my fair share, one I always think of and refer to questions like this is the slaughterhouse scene in In a Year With 13 Moons, it's a graphic scene inside where they turn cows into grocery meat. We hear a slow movement of Handel's Organ Concerto, while Volker Spengler the main star of the film recites in an unbelievable way a portion of a play that had to do with a tragic relationship of his which is shown a snapshot of in a previous scene. The words he speaks and how he says them,all combined with the music and the visuals of cows like that,and like i'll never forget it, and for me it's depicting what being a real artist is like, there's plenty of anguish involved. Fassbinder the director was going to off himself, but he decided to make In a Year With 13 Moons instead.
