Frank Dillane and Alycia Debnam Carey have been cast in the pilot for The Walking Dead companion series at AMC, created by Robert Kirkman, on whose graphic novel The Walking Dead was based, and Dave Erickson. Adam Davidson will direct.

The untitled Walking Dead spinoff, aka Cobalt, takes place during the same zombie apocalypse depicted on The Walking Dead but in a different location. It revolves around a male divorced teacher and a female guidance counselor. WME-repped Dillane (Harry Potter And The Half-Blood Prince) plays the woman’s son, who has battled a drug problem. Aussie Debnam Carey, repped by UTA, Management 360 and Lisa Mann Creative Management, plays the woman’s ambitious daughter.

This is the second consecutive pilot in which AMC has cast Debnam Carey; she also was in Galyntine. She made her American movie debut with this summer’s Into The Storm.

AMC Studios is producing.
