For those familiar with the Jaws movies and who were forever affected by the fear of a shark-feeding frenzy, this video is definitely a bit...er...triggering.
On June 20, 1975 a movie about an angry fish opened in about 500 theaters around the country. It was called Jaws, it was directed a guy named Steven Spielberg, it was scary as hell, and it changed the world forever. Its unique release strategy (wide instead of limited), intense television marketing campaign, and record-breaking box office essentially created the summer movie season (and made Spielberg a household name). 40 years later, regardless of its impact, Jaws remains a masterpiece, and a much better and more interesting movie than the vast majority of so-called summer blockbusters that it birthed.
