Best-selling French graphic novel "The Call of the Stryx" is headed to television, as revealed today by Deadline. The project comes from Element 8 Entertainment and GRID/AT-Anim, who have teamed up to bring the adult graphic novel to the small screen.

The live-action TV adaptation will be spearheaded by John Harrison, who directed the "Dune" and "Children of Dune" TV mini-series. His other credits include episodes of "Leverage" and "Tales From the Darkside" as well as the "Painkiller Jane" TV movie.

The graphic novel series -- which has remained popular in France for almost two decades, selling millions of copies in the country -- focuses on the partnership between a disgraced American spy and an enigmatic female mercenary as they try to clear the secret agent's reputation. Along the way they uncover secrets and mysteries, one of which involves a race of creatures that have existed on the Earth in secret.

"Provocative characters, epic storytelling, exotic locales, and a mythical creature that may not be all that it first appears, what more could I want?" John Harrison told Deadline. "Stryx is that rare graphic novel series that is a writers' dream come true."
