As AMC’s new Walking Dead spin-off starts to take shape, the walker-centric series has moved to cast three of its lead characters.

Courtesy of The Wrap, Unfriended: Dark Web’s Alexa Mansour (pictured), The Amazing Word of Gumball’s Nicolas Cantu and Bilched’s Hal Cumpston have all landed lead roles in this to-be-titled spin-off.

Details on this new show are being kept relatedly hush-hush right now, although we do know that the series will be based around two young females and will centre on the first generation to grow up in the midst of an undead apocalypse.

With Matt Negrete on showrunner duties, this latest Walking Dead spin-off has been booked in for a ten-episode debut first season.
