The Great Gatsby in 3D?

I read somewhere today that Baz Lurhmann’s planning to re-make The Great Gatsby… in 3D. Now, I understand making action movies or sci-fi movies in 3D, but The Great Gatsby? I’d think you’d want to concentrate on direction and set design, rather than 3D.Carey Mulligan’s slotted to play Daisy, a mis-step in my mind. She’s too gamine for the role. Leonardo DiCaprio and Tobey Maguire are also up for roles. What do you think of The Great Gatsby in 3D, and who do you think should play the lead roles?
