A trailer for director John Stockwell’s (Turistas) upcoming shark thriller Dark Tide is circling the web. The film stars Oscar-winning actress  Halle Berry as a diving instructor who returns to the island waters where she narrowly survived a great white shark attack.

The film was written by professional shark diver/journalist Amy Sorlie and costars Olivier Martinez (Unfaithful), Ralph Brown (Alien 3), Luke Tyler (Dredd), and Sizwe Msutu (In My Country). It was shot in South Africa off the coast of Seal Island in False Bay, home to over 64,000 seals and the sharks who love them.
