Doctor Who
It shouldn’t surprise you to learn that the venerable Doctor Who franchise, in its myriad forms, has pulled the “Earth All Along” trope on numerous occasions. The most recent was in season 12 episode “Orphan 55,” when the Thirteenth Doctor (Jodie Whittaker) and Team TARDIS decided to take a break at a futuristic spa. Unbeknownst to them thanks to some subtle teleportation, the spa was located on another planet, Orphan 55, a decimated wasteland full of monsters. It was, obviously, a far-future Earth, having been wrecked by climate disasters.
