This thread is fail.
New movies like Batman or Inception or Donnie Darko as the "Best Ever", lol.
My personal favorite, is "The Outlaw Josey Wales." But, it is not the best movie ever made.
With the likes of Citizen Kane, Casablanca, The Gold Rush, 7 Samurai, Battleship Potymkin, 2001 A Space Odyssey, Redbeard, Ran, Ikiru, Rashomon, Metropolis, Mr Smith Goes to Washington, Rear Window, City Lights, Modern times, Gone with the Wind, and The General.
Capra, Ford, Lang, Eisenstein, Kurosawa, Hitchcock, Kubrick.... these are the directors who made the best of the best. There are some truly great movies being made currently, but IMO, the best living directors are probably Chan Wook Park, Quentin Tarentino, and David Lynch... Maybe Speilberg, Coen Brothers, Aranovsky, Miike, Scorscese, and Copolla are up there too.... but they aren't of the same caliber IMO.
I love film, I love new movies, I love old movies. There's a reason why many of the classics are rated so highly and praised by so many, it's because they are just so damn good. They defined greatness in film, and have set the standard so high that they are almost untouchable.
Jimmy Stewart, Charlie Chaplin, Humphry Bogart, Buster Keaton; These names will live on through history because they the actors that defined great acting.
