The project, from EP Chris Morgan (Fast & Furious) and scribe Jason Fuchs (Ice Age: Continental Drift), centers on a late 19th century New York doctor and his family who relocate to a frontier mining town run by a powerful, but mysterious tycoon. Unfortunately, they quickly realize that not everything in the titular city is as it seems.

Gagnon, who also co-starred as Emily Blunt’s son in last fall’s sleeper Looper (pictured), will play Jack, the terminally ill nephew of the show’s central couple. Sweet, but chafing under the constraints of his illness, Jack later seems to flourish in the wild west, soon a healthy, energetic child. He’s also a talented artist, who has been drawing what he sees in his dreams; curious, yet ominous depictions of places and events in Big Thunder.
