LOL. I saw The Sting and the other movies I mentioned sometime after their first runs, as there were a lot of repertory cinemas in my area that showed movies a year or so after their initial release. I probably didn't understand a lot of these movies either at the time.
Re The Sting, I admit it took me awhile before I appreciated Robert Shaw (a really fine actor); I was too bedazzled by Redford and Newman.
