Avatar The Way of Water is dominating screens all over the world, closing in on two billion dollars at the box office as we record. But it’s not the first time James Cameron has been on a diving holiday – and we’re not talking about Titanic, either. 1989 sci-fi swimathon The Abyss was the superstar director’s first foray into the water (Piranha II doesn’t count), and although it flopped at the time, it has a great deal in common with his new, all conquering CGI epic. We submerge ourselves in the two films, and return to the surface with questions. Which film features 1960s dad? Which film relishes the darkness? And which of the two could really do with a few more jokes? Plus we play a new movie game and watch half of Glass Onion. Only half, mind you.
