The Vault sets for Amazon's Fallout show were built in a New York soundstage, but when Lucy steps into the Wasteland, the actors and crew ventured outdoors to shoot some of the scenes on location in a genuine ghost town and coastal desert.
Ironically, the desert in question is nowhere near Southern California. The joke about Hollywood pretending the whole world looks like LA wouldn't have applied to Fallout, which is actually set in the remains of California, but instead of using the state's real geography, the production spent multiple days filming in the Namib Desert on the coast of Southern Africa.
