I recently read an interesting comment on YouTube that masterpieces of film are just like masterpieces of art in that they can be remade but never perfected.
Asides from crappy plots and the shaky cam, who alive now could truly fit the shoes of Heston as Ben-Hur or Moses, much less Elizabeth Taylor as Cleopatra? Can there be anyone today who can be Dorothy Gale other than Judy Garland, Citizen Kane other than Orson Welles, and Norma Desmond other than Gloria Swanson? Who alive can replace Bogie as Sam Spade or Bogie as Rick Blaine or Bogie as Bogie?
People can try but trying is different from being.
