Watch the trailer. Have you seen this film? It is based on a short story by F.Scott Fitzgerald. If you liked the movie and want to read more about this american writer, visit http://www.sc.edu/fitzgerald/writings.html There you will find "The diamond as big as the Ritz" (which I recommend you) and others.
Ah, I almost forget: Fitzgerald is very well known thanks to his wonderful novel The Great Gatsby
