Norton plays Miles Bron, a billionaire tech mogul. In the film, he invites his friends for a getaway to his private island, where things quickly get out of control. His private island is home to the titular glass onion.
Though Bron might remind audiences of some real-life tech billionaires, Johnson said he tried hard not to think about any real people when writing, "The fact that Bron's a tech billionaire — which made a lot of sense for the story — became an obstacle in the writing. Because — I don't think I even have to say the names — there are some obvious, real-world analogs. And the instant I started thinking about any of them too specifically, it got so boring so quickly. And so, disconnecting him from that, and trying to build him as his own kind of clownish character, became a challenge," he told Deadline in November.
