'Walking Dead': 'Rescue Me's' Mike Zegen joins the cast

mike-zegen.jpgMike Zegen, who some may remember as firefighter Damian Keefe on FX's "Rescue Me," is joining the cast of AMC's "The Walking Dead." According to TV Guide, he'll be playing a new character -- Randall -- who isn't featured in the original comic book.

This isn't the show's first departure from the source material (but we have a feeling the author -- Robert Kirkman -- won't mind, since he's also a hands-on executive producer).

Norman Reedus' character, Daryl Dixon, is also a TV-only addition to the storyline -- and one that has worked out well for for both Reedus and the show since he's turned out to be one of the more popular characters.
