The Walking Dead was a comic book (or, possibly a graphic novel series - I'm not sure what the difference is these days) about the zombie apocalypse. Gory, gruesome and a bit bleak (unlike all those G rated happy zombie apocalypse stories!) it of course is now being turned into a television series for AMC.
Enjoy a look at the cast here. Supposedly, it's going to stay true to the tone of the book, though I'm not sure how that would be possible on a standard cable channel. Let's just say I wouldn't get too attached to any of the characters.
