Few directors have meant as much to film history as Steven Spielberg. From the 1970s, all the way to today, with his latest movie, Disclosure Day, Spielberg has created one classic after another. Thrillers, horror, war, even animation, Spielberg has done it all. The director also knows how important it is to deliver a powerful ending that stays in the minds of viewers long after the end credits roll. These eight movies are unforgettable for a variety of reasons, but it's their final acts and last scenes which put them on a different level as all-time greats.
