Yes, this is about the films (the 1971 original and the 2011 remake). But this is also about the meaning of the title, where the phrase came from and how it is used as a metaphor for failures and has-beens. I saw the 1971 film starring Dustin Hoffman and Susan George on TV. I was much too young to have been admitted to the movie house but you know how old films are shown on TV and that was where I caught it. Back then, there were hardly any controls and even ultra violent films were shown in the afternoon when any kid could see it.
