The trailer for the AMC "Walking Dead" TV show, originally shown at Comic-Con, has been released! The 4.5 minute video begins roughly where the comic book series begins: with small-town police officer Rick Grimes getting wounded in a shootout, and waking up in the hospital... in the middle of a zombie apocalypse. He sets off to the city in search of his missing wife and son, and finds more than he bargained for when he meets the swarms of undead waiting in the streets of Atlanta.

The show will premiere on AMC with a 90-minute episode on October 31st -- yes, Halloween -- at 10 PM EST, so mark your calendars, and check out the full video after the jump!
