AMC has released a new TV spot for the second half of the current season of The Walking Dead, which premieres on Sunday, February 9th.  Entitled “Don’t Look Back,” this teaser is packed with action and makes no bones about the fact that the little band of survivors will be challenged again and again during the remainder of the top-rated cable show’s fourth season.
 
The Walking Dead shows no signs of slowing down.  The final episode of the first half of the current season posted the best numbers ever for its midseason finale (see “Top Walking Dead Midseason Finale Ever”), and in defiance of normal patterns viewers for the series appear to be getting younger, a surprising indication that this mega-cable hit still has room to grow its audience (see “Walking Dead Viewers Getting Younger”).
