Elba signed a deal with Apple to produce original content through his Green Door Pictures production company. In February 2021, it was reported that the companies of Elba and his wife, Sabrina Dhowre, would be developing an Afrofuturist adult animated sci-fi series, tentatively titled Dantai, for Crunchyroll, which would be about a time when biotech has "created an ever-widening gap between the haves and have-nots." In an April 2021 interview with Den of Geek, he said the series is "mainly the brainchild" of his wife, whom he described as a "super geek when it comes to anime". In June 2024, Elba launched a new production company called 22Summers with former Pulse & BBC exec Diene Petterle. In August 2024, Elba received approval from the Tanzanian government to establish a film studio in Zanzibar. In September 2024, Elba joined Things Fall Apart as an actor and executive producer.
