According to Hollywoodreporter.com:
In its biggest development deal to date, AMC has acquired the rights to Robert Kirkman’s popular comic book “The Walking Dead” for a potential series.
Having AMC take home the rights to this seems like a good sign: they already produce the excellent Mad Men and Breaking Bad. Add Kirkman’s über-depressing (but so. damn. good) zombie epic to AMC’s development of the classic “The Prisioner,” and its previous acquisition of Kim Stanley Robinson’s Red Mars, and we could be looking at a network that’s positioning itself to give ol’ SyFy a run for its money!
