The Walking Dead (AMC, Sunday) -- 90-minute season premiere.

Next week, each of the three variants of "CSI" -- "CSI: Miami," "CSI: New York," and "CSI: Original Flavor" -- will take part in a "triple crossover" episode in which Laurence Fishburne goes around to all three cities because a killer has cast the various limbs of slain hookers across those cities.
