'Walking Dead' debuts intense trailer at Comic-Con

When you’re forced to wait a couple of hours outside on a hot July day to get into your favorite TV show's panel at San Diego Comic-Con, only one thing goes through your mind: This better be worth the wait!

Fortunately, the panel for AMC's hit series “The Walking Dead” did not disappoint.

Fans were treated to a tasty (and surprisingly long) sizzle reel of footage mixing season one scenes and new stuff from season two, which returns Oct. 16. Everything seemed amped up, especially the action. There’s a scene involving a horde of zombies on a freeway that looked INSANE. Check it out:

It was also revealed the new season will have 13 episodes, more than twice what the debut season offered.

And while fans love “The Walking Dead” as much for its characterization and tension as anything else, who are we kidding? The creative ways the show's producers find to "off a zombie" is a big part of the appeal.

Robert Kirkman, the creator of “The Walking Dead” graphic novel and a producer on the TV show, said he’s shocked AMC has let the show get away with some of the things it's shown -- the zombie mob munching on a horse in season one being a prime example.

“It’s become almost a contest to see how far they can push the envelope (in terms of zombie mutilation),” Kirkman said. “Everyone’s trying to see how they can come up with a zombie kill that will get AMC to say, ‘Huh uh, no way.’ ”
