Okay, I know this is early but I just heard about this today and I am SO EXCITED!!
The book American Gods by Neil Gaiman is being made into an HBO series that is expected to premiere in 2013. I read this book a couple of years ago and LOVED it! The premise was unlike anything I had read before. The main character (a regular guy) gets pulled into a world that is hidden from most humans, in which all gods who have ever existed actually have a corporeal presence on earth. However, the amount of power they have is directly correlated to the number of people who still believe in, and worship, them. So that homeless guy you pass on the street could be an ancient god that people have forgotten. BUT the old gods aren't the only ones. As society has developed people have started to "worship" new things: television, computers, and other technologies. So there are gods introduced that represent these technologies. A war is brewing between the old gods and the new and the main character has gotten caught up in it all. There is SO MUCH potential in this story for a fantastic series. Although, I'm not certain how HBO plans to draw it out into 6 seasons. There is additional speculation in this article.
