Who plays Henry in Silo season 3?

The story behind the answer

Reed Birney plays Henry in Silo season 3.

Henry is one of the season’s supporting characters in the underground society, whose tightly controlled hierarchy includes officials, technicians, miners, and residents assigned to specific levels. Birney’s casting is part of season 3’s expanded ensemble, which also introduces several characters connected to the silo’s earlier history and wider political machinery.

The name can be easy to mix up because season 3 features several prominent guest actors. Matt Craven plays Dr. Victor Crnkovich, Colin Hanks plays Per Stenson, and Billy Postlethwaite plays Hank Murphy. None of those actors is credited as Henry.

Birney is an American stage and screen actor known for extensive theater work and appearances in productions including House of Cards, The Blacklist, and Succession. In Silo, his role is a character credit rather than a recasting of one of the series’ central leads such as Juliette Nichols or Bernard Holland.
