Die hard fans of any franchise are willing to shill out big bucks to experience the movie or book in new and interesting ways. Most probably don’t realize that you can take a tour of the town where the Twillight series is based. Many other movies based in real locations, like the old Anne Rice novels, also have their own tours to see imaginary events.
Any of the current reality browsers (Layar, Point and Find, Wikitude, Metaio World, etc) could add walking tours of those locations with information about the books. The reality browsers with 3D capabilities like Metaio World could add the spice of recreations from the movies (yes, its probably a bit beyond what is currently available, but it’ll happen eventually).
There are thousands of other movies that have connections to the real world. Movie buffs would love to know if their favorite book or movie had been set at a locale they were visiting.
While we’ve seen a host of horrible movie tie-ins using augmented reality, I believe this one would offer an experience that would leverage the technology in ways to enhance the experience rather than waste some paper and printer ink.
