‘Unlike anything you’ve ever played’: Immortality, the video game that’s actually three movies

A video game exploring the treatment of women in Hollywood has set a new standard of sophistication. We talk to its creator and star

Every now and then you play a video game that you just cannot stop thinking about. Candy Crush might leave colourful imprints on the back of your eyelids. The Legend of Zelda: Breath of the Wild may creep into your dreams. And then, very occasionally, a game comes along that is so entirely unlike anything you've ever played that it becomes an obsession. Immortality, the latest from lauded game-maker Sam Barlow and his studio Half Mermaid, is one of those. It is something that has never existed before: a video game that is also three feature-length films, wrapped around a mystery so compelling that I couldn't concentrate on anything else for days. It is so delicate and complex that it's difficult to figure out how it even works.

The first thing you see when you load up Immortality is a talkshow clip from the late 1960s, in which a bright-eyed, red-haired young actor is being interviewed about her recent starring role in a film called Ambrosio, an adaptation of a 1796 novel about a devil temptress who draws a monk down the path of sin. This is Marissa Marcel, who was at this point on the brink of stardom - but this film she appears in, with an eminent but slimy director, is never released. Her next picture, an erotic thriller about art and murder, also never makes it into theatres. She retreats into obscurity for a long time, before emerging for a comeback in the 1990s in a Lynchian thriller about artifice and celebrity - but that film, too, is lost, and after that she disappears entirely.
