The film adaptation of the famous book The Great Gatsby opens the Cannes Film Festival on May 15. However, the film starring Leonardo DiCaprio is no longer competing for a Palme d'Or. F. Scott Fitzgerald's book is set in the 1920s and tells the story of a lonely veteran of the First World War. The story is told by a neighbor of the main character, but because he regularly lies, the truth about this mysterious Gatsby remains unknown for a long time. The neighbor is played by Tobey Maguire.
