Despite being set in the USA, Fitzgerald wrote most of the novel while in France.
Fitzgerald’s wife Zelda was originally uninterested in marrying him because of his rather poor financial situation. It’s believed that the relationship between Jay Gatsby and Daisy Buchanan is a reflection of their relationship. It would appear that The Great Gatsby is a fusion of reality and fiction!
I encourage you to pick up Fitzgerald’s book and read it in preparation for this weekend. I, for one, definitely plan on brushing up on The Great Gatsby prior to going to see the film. :)
