Amber Entertainment is teaming up with Penguin Books U.K. and Downton Abbey creator Julian Fellowes for the adaptation Atlantis: Revelation.

Marcus Blake wrote the novel, the first in a planned trilogy, which will be published by Penguin Books U.K. in October. The story is set in a world where the fabled city of Atlantis is actually real. Here's what Julian Fellowes, who will executive produce the adaptation, had to say about the story.

"There are few legends that seem to touch the very heart of our human story, but the tale of the Lost City of Atlantis is one of them, the dazzling civilization, beautiful, glamorous, rich beyond measure, that was plunged beneath the sea. It is an inspiring thought that this generation is to have its own retelling of the story, made even more so by the involvement of Penguin publishing, a company that has made the care of our literary culture their chief business for so many years."

Julian Fellowes will also oversee the screenplay's development, although no writer has been attached yet. Here's what Amber Entertainment co-founders Ileen Maisel and Lawrence Elman said in their own joint statement.

"Atlantis has been part of the collective unconscious and is a myth that is known all around the world. To marry this extraordinary story with a well-known thriller genre will make for both compulsive reading as well as for compulsive movie-going."

No production schedule was given for the adaptation.
