Even though some fans have criticized the teaser trailer for featuring more computer generated effects than most had expected, production designer Guy Hendrix Dyas assures io9 that Indiana Jones and the Kingdom of the Crystal Skull will be mostly CGI-Free.
Steven Spielberg estimated during production that 30% of the visual effects would be CGI, but mostly for elements such as backdrops and rotoscope removal of the visible safety wires during stunt sequences. Apparently, the finished film will contain only “a couple of hundred†effects shots, compared to Michael Bay’s Transformers which featured almost 650 effects shots or Sam Raimi’s Spider-Man 3 which featured almost 1,000 effects shots.
