By Chris Post San Diego Comic-Con is in full swing and that means fans of AMC’s hit zombie drama The Walking Dead are on a trip to spoiler town. The biggest spoiler so far has to be the epic trailer, which comes in at nearly 5 minutes long. It shows some footage we’ve already seen, but adds tons more. As the previously-released SDCC poster showed us, the trailer sets up a potential head-to-head conflict between Morgan and Rick. Fans who felt Season 5 was a little light in the undead department should also note that the trailer is HEAVY with zombies. We even see some that have weathered away to almost skeletons. Just how long can these dead keep walking? It’s still a long way to October, but at least we get a taste of the things to come. https://youtu.be/Va1UPrFXHKA
