The main casting's set: Carey Mulligan will play Daisy Buchanan, joining Leonardo DiCaprio as Jay and (likely) Tobey Maguire as Nick in Baz Luhrmann's upcoming Great Gatsby film.

The notoriously tedious 1974 version with Robert Redford, Sam Waterston, and Mia Farrow proved how difficult a novel this is to film. Should it be left on the bookshelf, or are you eager to see what this director and cast make of it? And what do you think would be the key to turning Gatsby into a great film?
