The Expanse is full of amazing actors, and it's adding one more to the list next season. David Strathairn will be heading into space for the third season of the hit SYFY show.

The network is keeping a tight lid on who the actor might be playing. I imagine they're likely planning the announcement for next week's San Diego Comic Con presentations, but he is said to be playing a significant character.

This won't be Strathairn's first visit to SYFY. While most audiences likely know him from his long career in movies, including his Oscar-nominated turn in Good Night, and Good Luck, he spent two seasons playing Dr. Lee Rosen on Alphas.

The Expanse is based on the bestselling book series by James S.A. Corey, so I imagine hardcore fans probably have a few theories as to who Strathairn could be playing. Fire at will in the comments.
