Apple TV+ has renewed Silo for Seasons 3 and 4, signaling the series’ conclusion with answers to its central mysteries. Rebecca Ferguson, who plays Juliette Nichols, shared her enthusiasm for adapting Hugh Howey’s novel trilogy and bringing the dystopian story to a close.

Silo has received a two-season renewal at Apple TV+ with its end confirmed. Based on a trilogy of novels by Hugh Howey, the post-apocalyptic drama follows the residents of a giant underground silo who are bound by regulations that they believe are meant to protect them.

Apple TV+ is renewing its sci-fi drama Silo for two more seasons — enough, it says, to bring the show to a conclusion. The series, based on a trilogy of novels by Hugh Howey, is midway through its second season on the streamer. The two-season pickup will allow the show to tell its complete story.
