“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.
