The fourth series has begun production just a few weeks after shooting wrapped on S3; the two runs were greenlit together, bringing the drama to a conclusion

The fourth and final series of Apple TV+’s dystopian drama, Silo, begins filming today (4 August) at a UK studio.

Silo is based on Hugh Howey’s bestselling trilogy, Wool, Shift and Dust, about a community comprising the last 10,000 people on earth, who live in a giant silo beneath the surface to protect themselves from the toxic, fatal outside world. None of them knows why or when the silo was built, and those who try to find answers face a deadly outcome…

Rebecca Ferguson stars and is among the team of executive producers, along with Yost, Michael Dinner, Nina Jack, Joanna Thapa, Ferguson, Morten Tyldum, Howey, Fred Golan, Rémi Aubuchon and AMC Studios.

Showrunner and executive producer Graham Yost has adapted the original source for the streamer; the series is produced by Apple Studios. The production is based at Hoddesdon Studios in Hertfordshire, with previous runs having also used OMA One Film Studios and OMA X Film Studios.

When the third and fourth series were jointly greenlit, Yost said: “It has been a richly rewarding experience to adapt Hugh’s epic novels with our partners at Apple, and we are thrilled to have the opportunity to bring this complete story to the screen over the course of four seasons.”
