It started with a simple premise: Nathan Fielder uses HBO’s unbelievably large budget to stage immersive replicas of social situations so members of the public can prepare for difficult conversations no matter what goes wrong. Now, in Season 2, Nathan is setting his sights to the skies by trying to help pilots assert themselves and prevent crashes. But Nathan soon discovers that the ranking member of the Aviation Subcommittee is also part of the Autism caucus, and he finds a different way in. Nathan’s replica airport becomes a great asset for autistic children, even as Nathan is hesitant to make the connection. HBOIt’s no secret that the “Nathan Fielder” character we see in The Rehearsal and his previous show, Nathan For You, is not the true personality of Nathan Fielder the comedian.
