Semiotics are the study of signs and anything that "stands for something else".Denotation - What we see when we look at an image
Connotation - Other hidden meanings of what we see.
In this cover of the film we can see many different connotations and denotations of this. Firstly the denotations are the image of the sharks finn, the dull/dark weather in the background. We also see the two people with a very worried look on their face awaiting what will happen next. The connotations are the dark weather can show the sea is a very dangerous place and the lightning can show shomething could strike you at any time. The larger shark finn can show sharks are a very imposing creature in the sea and something to be very weary of.
