According to The Hollywood Reporter, the AMC smash has tapped Greek alum Andrew J. West to guest star for a major arc (with an option to become a regular in season 5).
West will play Gareth, a character who does not appear in the long-running Image/Skybound series on which the AMC show is based. However, sources tell THR that while Gareth might not be playing someone from the comics, he is a remix of sorts of an unidentified character from the series. Gareth will have what sources say is a big presence and play an important character on the drama from showrunner Scott M. Gimple.
'The Walking Dead' airs every Sunday on AMC.
