To start I looked at the trailer and alternate scences as it shows some key points of the story and the costume. The deleted scenes are parts from the novel. I then read the novel and looked at character breakdown and costume plots.
Alternate Movie ending which is the same as the Novel:
Deleted scene – Nick and Jordan:
Deleted scene – Voice full of money:
Looking at these scenes helped me to understand the story and the costume, these scenes are in the novel but were cut out of the movie.
Then I looked at the silent movie trailer from 1926. The difference in costume and how the story is portrayed can be seen just by comparing these. There is also a 1974 version of Gatsby which I watched.
