In the last few months, in the stream of post-Avatar money and praise, James Cameron has repeatedly hinted at a handful of projects that might be his next-- Avatar 2, of course, plus the long-in-gestation Battle Angel Alita, and a project based on the nonfiction book The Last Train from Hiroshima, about the atomic bomb attack on Japan in 1945.

Now we know that one, at least, is almost definitely off the table. The Associated Press reports that the publisher has pulled the book from their lineup, following a series of investigations into its veracity. Author Charles Pellegrino has acknowledged that one of his interview subjects lied about being on the Enola Gay, which dropped the bomb, and now the publisher has been unable to confirm the existence of two people mentioned in the book.

Even Pellegrino himself may not be what he claims-- he's said he has a Ph. D from Victoria University in Wellington, New Zealand, but the school has no proof of that. Pellegrino and Cameron haven't commented on the halt of publication, but it's pretty fair to assume that, no matter how much Cameron likes the book, he won't step into the minefield that comes with a book proven to be untrue. Remember the hellstorm that Oprah unleashed upon James Frey when the facts of A Million Little Pieces came under dispute? Imagine all that coming from the King of the World instead. Though nothing is confirmed yet, it's fair to assume Cameron's schedule just got a little freer.
