Jaws Opening Scene - Conventions Used

In the opening scene from the 1975 film 'Jaws' a wide variety of different codes and conventions of Horror films are used. The first one that the audience see's is the two characters seperating from the rest of the group and going to a secluded location on the beach which hints that something is likely to happen to them. As is shown a character dies within the first 5 minutes of the film which is a very common convention that is used in almost every single horror film to set the atmosphere. Similar to the phone lines being cut the victim in the scene is shouting and screaming however is not being heard as the other guy on the beach is out of ear shot. We also see the victim cowering trying to get away from the threat in the sea however it breaks through the surface of the water and drags her under. In this scene the audience also witnesses a warning that goes unheeded as someone tells her not to go into the sea however she doesn't listen and proceeds anyway.
