Sometimes, what's not said is just as important to the writing as what is said. As a writer, we have our voices heard. I think that, at oftentimes, the ability to allow the dialogue to recede properly into the world of the film is also a really valid sort of way to be a writer, I think.
Whereas 'Avatar' and other movies get shocks out of their three-dimensionality, 'Gatsby' is going to be about inviting the audience into this larger-than-life drama, letting them almost be inside the room rather than looking at it through the window. I think it will really work.
