Query: Tremendously fun to watch

Best viewed in a dark room on a large screen surrounded by 300 strangers eating popcorn. This movie will (hopefully) thrill you down to your toes; it is one of the few sound pictures that uses film purely for its purpose: to tell a story with pictures. Ahead of its time for 1968 and still is.
