It has been claimed that a spinoff series set in the same universe may be in development for Apple TV’s science-fiction series Silo, which is expected to conclude with its fourth season, planned for release next summer following the third season. According to the claim reported by Sigmund Judge, the production will be based on an as-yet-unpublished novel by Hugh Howey and will focus on events surrounding Silo 40. While Apple has not confirmed the project, Howey is denying the claim. Judge stated that although filming on the fourth season was completed in March, the sets have not been dismantled for approximately six months. This raises the possibility that the sets could be reused, but does not confirm the project. Details about the book, cast, creative team, filming schedule and release schedule are unknown.
Why it matters
This rumor raises the possibility that the Silo universe could continue on screen after the planned finale of the main series; however, the information currently available does not elevate it to the level of a confirmed production. For viewers, the most important uncertainty centers on whether the potential project would establish an independent story or how it would relate to the narrative of the existing series. Basing it on an unpublished novel also currently prevents any insight into the scope of the story and its characters. Apple’s lack of confirmation and Hugh Howey’s denial of the claim show that the observation concerning the sets cannot, on its own, be considered evidence. Therefore, the project’s cast, creative team and release plans remain unclear, as does its existence.
