“It’s no secret that as an ocean explorer now, as an avid scuba diver for many years before that, and as a fan of ocean exploration when I was a kid, I’ve had this romance with the ocean my entire life,” James Cameron once told National Geographic while explaining the inspiration for Avatar: The Way of Water. The 2022 Avatar sequel isn’t the only Cameron film about water; Titanicmakes effective use of the element, and Cameron also helmed an aquatic monster flick for his feature debut in Piranha II: The Spawning, whose production was infamously fraught. But the film that best exemplifies Cameron’s lifelong fascination with water is The Abyss, the 1989 science-fiction horror that breaks genre conventions in unexpected ways.
