A girl named Chrissie Watkins leaves a beach party at dusk on Amity Island and goes skinny dipping. While swimming out near a buoy, she is seized by something from below; it thrashes her around and drags her underwater. The iconic opening scene of Jaws is burned into the memories of the millions, as well as the equally iconic line “smile you son of a bitch” said by Brody just before he blows up the Great White shark responsible for terrorizing Amity Island. Jaws is based on a novel by the same name written by Peter Benchley. The poster image featuring the shark approaching a lone female swimmer was designed by Roger Kastel of the Seiniger Advertising agency in 1975; principal Tony Seiniger explained that “no matter what we did, it didn’t look scary enough”. Seiniger ultimately decided that “you had to actually go underneath the shark so you could see his teeth.”
