Deadline is reporting that David Strathairn will be joining the cast for a major recurring role in SyFy’s third season of The Expanse.
The Expanse is a series based on the best-selling book series of the same name by Daniel Abraham and Ty Franck. The story unfolds across a colonised galaxy 200 years in the future, when two strangers become unwittingly swept up in a vast conspiracy.
The report doesn’t state what role Strathairn will be playing but it’s described as a substantial character with a significant arc. The third season will be another 13-episode run and will be out sometime in 2018. Mark Fergus and Hawk Ostby serve as showrunners on the series and also executive produce alongside Naren Shankar. The Expanse stars Steven Strait, Shohreh Aghdashloo, Dominique Tipper, Cas Anvar, Wes Chatham, Frankie Adams and Thomas Jane.
