Citing sources familiar with the matter, Sigmund Judge claims that Apple TV is commissioning a “Silo” sequel. Judge, who has been right about things like this in the past, says that there are still some standing sets, and hires for the project have begun. Obviously, there’s no premiere date, given that production hasn’t started.
Exclusive: Silo’s fourth and final season will be succeeded by an expansion/spinoff at Apple TV.
I am told that the upcoming project – beginning pre-production later this year – will tie into Hugh Howey’s highly anticipated Silo 40 book trilogy, expected to publish next summer. pic.twitter.com/wCnXvlUOif
