AMC’s award-winning The Walking Dead webisode series returns to amc.com and AMC’s YouTube Channel on Sun., Oct. 1 with three new installments. The newest series –- The Oath –- was executive produced, directed and conceived by Greg Nicotero, executive producer, director and special effects makeup designer on the hit show.

In the three webisodes (7 to 10 minutes each), the lone survivors of a massive walker-attack, Paul (Wyatt Russell, Cowboys and Aliens) and Karina (Ashley Bell, The Last Exorcism), speed across the countryside, frantically searching for an aid-station, as one of them slowly bleeds out from a wound. Finally coming upon a hospital that has not been overrun at first feels like a blessing, but could soon turn to misfortune, as a seemingly benevolent doctor (Ellen Greene, Little Shop of Horrors) may hide a darker agenda.

Right on the heels of directing Season 4′s premiere episode, Greg Nicotero focused his sights on the most ambitious The Walking Dead webisode series yet. “There’s walkers, gore and new threats lurking around every turn — all the elements that fans The Walking Dead will love!”

Nicotero further commented, “The webisodes give us a unique opportunity to see other parts of the ravaged world of The Walking Dead while weaving in and out of our show. The crossover between The Oath and The Walking Dead ties in one of the most iconic images from the series, and gives us insights and history to yet another timeline. I had worked with Ashley on The Last Exorcism and brought in Wyatt and Ellen, who rounded out the brilliant cast perfectly.”

“The Walking Dead audience is passionate and enthusiastically interacts with the show and other fans online. Being able to develop new ways for them to experience the world of The Walking Dead, like these webisodes, is a no-brainer,” said Mac McKean, senior vice president, digital media, AMC. “They tell a great story with high production values, and they perfectly complement AMC’s extremely popular The Walking Dead digital experiences — games, second screen experiences and interactive content.”

The previous two seasons of amc.com’s The Walking Dead webisodes have won back-to-back WGA, Streamy and Webby awards. The webisodes are produced by Alloy Digital/Generate with Chris Pollack, Jared Hoffman, Greg Nicotero and Michael Petok serving as executive producers.
