This weekend is the weekend that millions of people have been waiting for. On Sunday, there will be a huge event on television. Yes, we're talking about another Walking Dead marathon. Starting on Sunday, February 3 at 3 PM ET, AMC will begin airing a marathon of Walking Dead season one episodes. The Walking Dead marathon kicks off with "Days Gone By," the very first episode of season one of The Walking Dead. The Walking Dead season one marathon will also include "Guts," "Tell it to the Frogs," "Vatos," "Wildfire," and "TS-19." In addition to the marathon of previous episodes of The Walking Dead, AMC will also be airing The Walking Dead: First Look at 6:35 PM ET, which is just five minutes after kickoff of some little sporting event on another network. We assume The Walking Dead: First Look will be a preview of the second half of The Walking Dead season three. All six of the season one episodes of The Walking Dead will air twice during the marathon, which runs through Monday, February 4 at 4:30 AM ET. AMC will air a marathon of season two and season three to date episodes of The Walking Dead next weekend. The Walking Dead season 3 mid-season premiere will air on Sunday, February 10 starting at 9 PM ET on AMC.
