At the Walking Dead panel at this past weekend's C2E2 comics-and-other-geekery convention in Chicago, one of the undead hit's stars let slip that the horror luminary might be saddling up for a tour in zombieland.
While fielding a question about whether executive producer Frank Darabont would be directing the second season's premiere—the answer was no, by the by—Laurie Holden shifted giddily in her seat (at around 10:45) and said:
"I heard a rumor that Stephen King's gonna write one."
Now, that is still, as Holden states right up front, a rumor. But, it's a rumor from The Walking Dead's inner circle. And Darabont and King have a very long history together—The Shawshank Redemption, The Green Mile and The Mist—so another collaboration wouldn't at all be out of the realm of possibility.
