THE PLANET OF THE APES (1968) -- original film version, with a "far-out" score by Jerry Goldsmith (a prolific composer who amassed a very large fan base). This is a link to the opening segment, which includes a prologue delivered by the hero, an astronaut (played by Charleton Heston), and then the titles. (Note that such "prologues" were pretty uncommon at the time; the conventional ways of setting up movies were starting to give way to innovative methods.)
