“I’m so grateful to everyone at TNT and Tomorrow Studios for letting me join the riveting world of Snowpiercer that Graeme and Aubrey [Nealon] have so beautifully crafted and built,” said Zbyszewski (via Deadline). “We have an exciting fourth season planned, and I can’t wait to be on set with such an incredible cast and crew as we continue to explore new worlds, create new mysteries, and develop character relationships.”

Zbyszewski is known for creating the ABC sci-fi series Day Break, where he worked as a co-executive producer and writer for the show’s short run in 2006-2007.

His other memorable TV roles include FBI Special Agent Mike Casper in the NBC political drama The West Wing and Richard, ex-husband of Christine Campbell, in the CBS sitcom The New Adventures of Old Christine.
