These two posters are the posters for the film Jaws, the left is the original poster and the right is the re-release poster. Although they both look very similar, the second poster shows quite a few differences. For example, the sky in the right poster has now got more of a realistic view to it with the clouds and the sunset which means that the film itself should have better pixels etc and will be more realistic which is exciting for the audience.
The shark in the second poster also looks more realistic as it has clearly used a computer programme that's well updated to make to shark look more frightening, whereas the original poster looks as if the shark has just been drawn on with a pencil.
The colours on the poster even have a different effect to them. They are much more stern and bright, attracting the audience to the poster and making them more excited to watch the film itself.
An important thing to take note of on this poster is that it has the title "40th" Anniversary release" clearly on the poster and also has the re-release date on it which is important for the audience.
The poster on the left is the original poster for the film ghostbusters and the one on the right is the 30th anniversary re-release poster for it. There isn't much difference between these two posters but in the right poster is does actually feature the actual ghostbusters themselves and of course the fact that it's the 30th anniversary is included on it. However, unlike other re-releases this film is just being shown again in cinemas for one week only as stated on the poster itself.
