Terribly arbitrary I know but here is the game I was playing. I was watching Crimson Tide and mention was made of Run Silent Run Deep and as a lover of sub movies I went to IMDB to see if I had rated it. I then clicked on Burt Lancaster and chose filmographies by ratings to see if I had missed rating any of his movies.
I was amazed to find he had appeared in 35 movies rating 7.00 or better which generally means a pretty good movie. Looking through the list there are a lot of fine movies. It does include two TV movies but they are both award winners.
I then wondered who had been in more: DeNiro? No only 26. Pacino? A mere 28. Well obviously Charlie Chaplin. Nope, 22. A woman maybe, Meryl Streep? Ha ha, 13. Katherine Hepburn then? No, just 21. Oh, of course, the greatest film actor of all time, Jimmy Stewart. Bingo 36!
Any other ideas for who has the most?
