Incredible documantary.... stunning photography and camera work by Roger Horrocks....what an effort and experience from Craig Foster...he has been fantastic in the narration.... Octopus moving on your body in the middle of the ocean...what an experience... giving chills even while watching it....but the real Hero is of course the Octopus.... such an intelligent creature....makes us humans looks like mediocre in terms of intelligence and survival capabilities....super film.
