Good news Walking Dead fans, the book’s main protagonist Rick Grimes, the one armed bad-ass, and all around good guy considering he’s been living through the zombie apocalypse, has been cast, and he’s a Brit. Andrew Lincoln has been tapped to portray the sheriff turned survivalist.  This usually means good things, as HBO has shown us (see Generation Kill), so my already high hopes for this mini-series are now beginning to reach unrealistic levels.
