Sean Hood, whose credits include Conan the Barbarian and Halloween: Resurrection, will adapt the novel, published in 2015. The story revolves around an idealistic young filmmaker who sets out to the Mariana Trench with a small crew to film a faux documentary about mermaids. But the hoax soon turns real as sailors begin to disappear and the filmmaker realizes that they are under siege by actual mermaids. A fight to survive at any cost ensues.
“‘Rolling in the Deep’ is a film led by complicated badass female characters,” Lambert said. “I’ve been waiting to make a film like this my entire career. Our mermaids are not cliché sugary cartoon princesses; they will take you down if you stand in their way.
