Furious 7 helmer James Wan has closed his deal to direct Aquaman, the Warner Bros film that sets former Conan The Barbarian and Game Of Thrones star Jason Momoa as the sea-dwelling superhero, the reluctant ruler of Atlantis. It brings Wan back to the studio where he made The Conjuring and is working on the sequel, at New Line. Wan was long rumored to be swimming toward this project, and it gives Warner Bros a proven hitmaker to helm another film in the DC Entertainment slate that includes the upcoming Batman Vs. Superman, Wonder Woman and the Justice League films. In this, Aquaman is caught between a surface world ravaging the sea, and the Atlanteans who are looking to lash out in revolt.

“The Aquaman film will be a major tentpole picture for us and James’s span of work has proven him able to take on any manner of project, bringing his incredible creative talent and unique voice to the material,” said Warner Bros’ Greg Silverman in an announcement.

Wan will oversee the script from Kurt Johnstad, and Charles Roven, Deborah Snyder and Zack Snyder are producing. Pic is set for release in 2018.
