I don't think anyone has done anything (casting, script, locations, pre-production, etc.) on this yet, other than talk about it and spread casting rumors (ie Christopher Walken as Ozzy). The book was great, and while it could make a cool movie, I have a feeling this is a project that will float around for a long time, then be a direct to DVD release. Here's hoping for the best, but really, how long have they been talking about this?
