EXCLUSIVE: Alex Russell has been tapped for a starring role in AMC drama pilot Galyntine. Written by Halt And Catch Fire‘s Jason Cahill and executive produced by Scott Free and The Walking Dead‘s Greg Nicotero, the fantasy-action adventure with hints of sci-fi is set in a postapocalyptic future without technology where a band of survivors is forced to adapt to isolation and the challenges of their new world. Nicotero is also directing the pilot, stepping in to replace original director David Mackenzie, who left in May owing to creative differences.

Russell, repped by UTA and United Management in Australia, will play Roman, an orphan who was unofficially adopted by his best friend Aethys’ family, and he hopes to marry Aethys’ sister Essyn to make his membership in the family official. A very public victory appears to cement his status as a future leader of the colony, but a twist of fate (and a deeply wounding betrayal) set him on a different, more dangerous path. Catherine Dent and Charlotte D’Ambroise already have been cast in the pilot, which was greenlighted in November for 2015 series consideration.

Russell recently wrapped Angelina Jolie’s Unbroken and Cut Snake. His previous film credits include Carrie and Chronicle.
