More (actually less) on the movie based on "2012: The War for Souls"

“It’s a book we just set up at Warner Brothers by Whitley Strieber who wrote The Hunger and Wolfen and who’s also a famous alien abductee. It is his latest theory of what’s going to go down in 2012 based on the Mayan calendar and based on factual astronomical convergences are going to happen on that day, said Roberto Orci. “We really like the initial concept. We always try to be extremely free with what the dictates of the live action story need to be. If it ends up being extremely similar to the book, great. But we don’t stick to anything just because it’s there. We question everything.”

So basically, none of us have read the book yet, and the movie will be somewhere between a precise rendition of the book, and nothing like it. It may, or may not, be directed by Michael Bay. More info.

BTW, aside from his horror novels, Strieber wrote Communion (a non-fiction account of alien abduction) and co-authored the book the became The Day After Tomorrow movie. Watch this guy, he is quite unique in terms of 2012 knowledge, cataclysmic predictions & aliens (or not, he calls them "visitors").
