While focusing on the Bell System's building, whose attraction is definitely a precursor to Spaceship Earth, it does give a nice overview of the fair as a whole, including quick glimpses of the State of Illinois pavilion (home of Great Moments with Mr. Lincoln), the Ford pavilion (which used the same transportation system as the Peoplemover, except you rode in a Ford and where you also saw the dinosaur scenes now seen on the Disneyland railroad), the GE pavilion (which housed the Carousel of Progress), and the Pepsi pavilion which housed "it's a small world." There are even a few familiar faces that pop up and some catchy folk music.
