Could a Dragonriders of Pern movie be coming soon to a theater near you? While Warner Bros. has worked hard to find some suitable franchise replacement for Harry Potter since the highest grossing film franchise of all time came to a close three years ago, it has thus far come up empty. The studio bought some time when Peter Jackson’s The Hobbit adaptation expanded to three films, but that’s coming to an end this December with the release of The Hobbit: The Battle of Five Armies. And so WB continues to search hard for another franchise that might spark as big as Harry Potter (I’m not sure there’ll be anything like Harry Potter again for a long, long time—if ever), and their latest play is author Anne McCaffrey’s long-running Dragonriders of Pern book series. More after the jump.
