Silo is the story of the last ten thousand people on earth, their mile-deep home protecting them from the toxic and deadly world outside. However, no one knows when or why the silo was built and any who try to find out face fatal consequences. Rebecca Ferguson stars as Juliette, an engineer, who seeks answers about a loved one’s murder and tumbles onto a mystery that goes far deeper than she could have ever imagined, leading her to discover that if the lies don’t kill you, the truth will.

Rebecca Ferguson, the star of Apple TV+’s critically acclaimed series Silo, has revealed ambitious plans for the show’s future, hinting that the final two seasons might film at the same time, potentially wrapping up the series in a dramatic finale, as she exclusively revealed during a chat with Collider‘s Steve Weintraub to talk about the hit series. The dystopian series, based on the bestselling Wool trilogy by Hugh Howey, has been a critical hit and one of Apple TV+’s best-received shows.

The lush, big-budget adaptation has expanded the scope of Howey’s universe, planning to stretch the three-book series across four televised seasons. Discussing the intended lifespan of the series, Ferguson noted that they’ve already got an ending in sight, and that there were plans in motion to film the final two seasons concurrently to get the work done as efficiently as possible.

I believe that the show has an ending, and I know when that is. So that’s the answer. You will find out when the show is done. To be honest, I don’t think it’s a secret. The books are the books. It’s three books, and the three books are divided into four seasons. So I believe, unless any Apple person is gonna jump on, I think we’re absolutely fine with saying Season 1, we’ve done. Season 2 is shot and coming out, and we’re now looking at green-lighting Seasons 3 and 4. And I think we would film them maybe together, and that would be the end. – Rebecca Ferguson
