In a cavernous studio outside Madrid teeming with TV industry stars, Netflix is blending old knowledge with modern technology to try to concoct a successor to its global hit Money Heist. The dystopia Billionaires’ Bunker, released yesterday and set in a gigantic underground fortress offering gyms, a garden and a fancy restaurant, is the US streaming giant’s latest Spanish super-production. The aim is to conjure the magic of Money Heist, a series about a group of wily robbers who hold up the Spanish national mint, which was Netflix’s first non-English-language global success after launching in 2017. Migue Amoedo, visual artistic director of Billionaires’ Bunker, described Money Heist as “the turning point of the industry”, saying they now had “the recipe” for repeating its success. Spanish screenwriters Alex Pina and Esther Martinez Lobato were behind Money Heist, its spin-off Berlin and Sky Rojo, productions that underline the potential for local settings to reach worldwide stardom.
