Number One scariest movie

The movie Jaws is known to be one of the scariest movies of all times. This ties also into people being scared of the dark. The things that scare people the most is the stuff they cant physically see but you hear about, like the boogyman. The opening scene of Jaws is very scary to most people, because you don't actually see the shark. All you see is two happy people, then one gets sucked under the ocean. This may also be horrifying to people because people go swimming everyday all over the world.
