Which actor plays Ed Harwood, head of the mining level, in Silo season 3?

Ned Dennehy plays Ed Harwood, the head of the mining level, in Silo season 3.

Ed Harwood belongs to the working infrastructure of the silo, where mining and the Down Deep help sustain the enclosed society. His position gives him influence over one of the most physically demanding parts of silo life and places him among the characters who represent the practical labor keeping the settlement operating.

The casting can be confused with other season 3 supporting roles. Will Merrick is credited as Danny Bly, Akie Kotabe as Diego, and Chris Fulton is not the actor credited as Ed Harwood. Dennehy’s role is specifically identified with the mining level and is separate from the show’s central administrative and judicial characters.

Ned Dennehy is an Irish actor known for work in television, film, and theater. His screen credits include Peaky Blinders, Versailles, The Tudors, and The Peripheral. In Silo, his appearance adds another layer to the series’ social structure: the story is not only about sheriffs and engineers, but also about the miners and industrial workers whose labor supports life deep underground.
