Warner Bros. Pictures has picked up the rights to the James A. Owen children's novel, Here, There Be Dragons; David Heyman and David Goyer will serve as producers on the film.

The book, released next week, focuses on three strangers - John, Jack and Charles - in London during World War I; they become entrusted with the Imaginarium Geographica, an atlas of all the lands that have ever existed in myth and legend, fable and fairy tale. The Hollywood Reporter adds they end up traveling to the Archipelago of Dreams, fighting the dark forces that threaten two worlds. It is later revealed that the three are future fantasy authors J.R.R. Tolkien, C.S. Lewis and Charles Williams, who met in real life at Oxford and enjoyed a competitive friendship.

Here, There Be Dragons will be part of a six part series for Owen to release one each October.
