[3] The series takes place in 1950s Spain and consists of three episodes revolving around a conservative and traditional society during the Franco regime "where appearances and family ties play a key role".

[4] The series features an all-star cast,[5] including Carmen Maura and Caro regular Cecilia Suárez.

[8] After his successful Netflix series The House of Flowers, Caro was signed to an exclusive deal with the streaming company, and began production on a new three-part miniseries, Someone Has to Die.

[5] Some parts of the second season of The House of Flowers had been set in Spain, with Manuel Betancourt of Remezcla suggesting that the country had become his "latest muse".

[10] Caro has called the cast of the show "a dream"; he had worked with several of them before: Suárez is his constant collaborator and Casanova was in the Spanish scenes of The House of Flowers.

[3] Betancourt wrote that the inclusion of "Pedro Almodóvar's OG muse" in Maura made the series a "must-see event".

[3] Maura had visited Caro and Suárez while they were filming in Madrid for The House of Flowers in February 2019 to discuss the show.

[9] John Hopewell of Variety wrote that, by putting actors like Maura and Suárez together, Caro was "furthering [the] Spanish-language star system".
