MTV is developing a series based on Terry Brooks’s hugely popular Shannara fantasy novels, the network announced today. Jon Favreau will direct the pilot, and Smallville co-creators Al Gough and Miles Millar will write and produce the show. The Shannara saga includes 25 books, but the first season of the show will be based on The Elfstones of Shannara, which is the second book in the series. (Well, the second book that was released; there are many prequels.) The idea of a Shannara TV show has been floating around for years, but perhaps in this Game of Thrones–crazed world, an expansive fantasy series suddenly seems like a safer bet.
