AMC has confirmed that the alternate version of the series opener will receive its world television premiere on July 8, preceded by all 19 episodes of the series over the course of two nights.
The marathon will also include a sneak preview of Walking Dead season three, and feature introductions and supplementary material courtesy of Talking Dead host Chris Hardwick.
A live primetime special edition of Talking Dead will air on July 8 at 9pm, followed by the pilot at 10pm. Plans to screen the episode in other territories are yet to be confirmed.
The alternate pilot was "created specifically for fans of The Walking Dead", which is based on an Image Comics series that is rendered in black and white.
The Walking Dead returns for its third season in October.
