James Cameron probably sat up in bed one night and thought: “How can I ramp up the already off-the-charts hype surrounding my biggest blockbuster ever, Avatar? I know: a book!” Yes, it’s true. Cameron confirms that he is writing an Avatar novel. “There are things you can do in books that you can’t do with films,” he explained. Cameron says the book will follow the plot of the movie “quite closely,” but that it will include extra details and “interior monologues.” He hopes that, like the movie, the Avatar novel will help bring attention to environmental causes. The film has already grossed more than $666 million domestically.
