Don’t get too excited by the prominent placement of James Cameron’s name above the title of this 3D-enhanced deep-sea diving adventure. This isn’t the director’s official follow-up to the wildly successful Avatar; he’s not actually stepping back into the director’s chair until Avatar 2 and 3 start filming sometime next year. Cameron merely executive produced Sanctum and lent the production the special 3D cameras he had developed for his sci-fi extravaganza.
