The movie hasn't been greenlit yet (as far as I know). This trailer is basically a "business proposal" in which the filmmakers hope some studio will see it and offer them the job to make a feature film out of it. The makers of the trailer seem extremely confident that this film will get made since they have a target release date of 2012 or 2013. I have to say - I'm interested.
