Whenever I think of CGI, I think about the chariot race in "Ben Hur," where they built the whole structure and filled it with literally thousands of live extras, as opposed to "Gladiator," where almost the entire Roman Stadium was CGI, or "Avatar," where most of the entire movie came out of a computer.
Compare the original "King Kong," where Kong's fur rippled constantly because of the animators' fingerprints in it and the biplanes who were so obviously models, and bad ones, at that, as opposed to Woola or Tars Tarkas in "John Carter."
We've come a long way, baby.
