Lock your doors. Cancel all other plans. This weekend belongs to The Dead. The Walking Dead Season 3 Preview Weekend kicks off this Sat., Jul. 7 and Sun., Jul. 8 beginning at 11:30AM/10:30c each day. The two-day event will feature a marathon of all 19 episodes from the series' critically acclaimed first two seasons, a Talking Dead live primetime special on Sun., Jul. 8 at 9/8c and the world premiere of the black-and-white version of The Walking Dead pilot episode on Sun. at 10/9c. .

In the hour-long Talking Dead event, host Chris Hardwick will give fans a first look at The Walking Dead Season 3, including a scene from the new season, and brand new video interviews with the cast, a tour of the new set and a sneak peek at the props and wardrobes featured in Season 3. Hardwick will also sit down with in-studio guests including the show's executive producers and other celebrity fans to discuss the show and answer viewer questions.

At one point during the live show, Hardwick will also provide a special code to viewers, which they can use to enter The Walking Dead Watch to Win Sweepstakes. The winner will receive a trip to Atlanta and a "stagger on" role as a zombie on the hit show.

The on-air event will be complemented by activities online at amctv.com, where fans can find more exclusive behind-the-scenes videos and participate in Fan Favorite polls that cover topics like Best Weapon for the Apocalypse and Favorite Deadly Zombie Attack. The Poll winners will be announced by Hardwick during the Talking Dead live event Sunday night.
