Check out these two trailers for “The Day The Earth Stood Still”: the first is from the original 1951 version, the second from the 2008 remake. You’ll note that the 1951 version lacks a lot of things, including superfluous special effects and Will Smith’s son making Keanu Reeves look like Laurence Olivier, but it also approaches the marketing of the film completely differently.

Trivia: There were two Gort suits in the 1951 version: one that laced up down the back for when he had his front to the camera, another that laced up in the front for the shots of his back.
