I hope the film is successful enough to make this thread worth starting, but I want to talk about this and have not had the chance to with anyone IRL. So many references to unearth (some of which are no doubt empty or red herrings). So many questions about the Untethered - practical as well as existential. My first thought was 'where are all the staff to run this?' If you're running a secret programme with doubles of the entire population in tunnels underneath America, the logistics of it are mind-boggling. And if they're subsisting on raw rabbit, they wouldn't last long as anyone whose ever watched QI or Ray Mears will know. And when a person travels does their double go somewhere too? What if they go on holiday abroad?
