AMC has released a new, action packed preview of The Walking Dead. The show will begin its Sunday night airings on October 31, 2010; this Halloween.

I’ve mentioned it before, but this is based on the excellent comic series by Robert Kirkman. If AMC adapts this well, they have years of shows ahead of them.

AMC has also released a pretty cool looking poster with protagonist Rick Grimes (played by Andrew Lincoln) riding into Atlanta after the outbreak. Click the thumbnail to explode the image.
