Premiering on Halloween 2010, in 120 countries simultaneously, The Walking Dead became a cultural zeitgeist practically overnight. A deserted car wreck. A policeman walking through it. The back of a little girl. He calls to her. At first she doesn’t respond. Then she turns around… revealing that all is not quite what it seems. The cop– left with no choice– shoots her, and as she falls, the tremolo string arpeggios of the “Main Title Theme” by McCreary crescendo, drawing millions of viewers into this harrowing world of The Walking Dead.
