Frank Darabont recently talked about the possibility of Stephen King and his son Joe Hill writing an episode of The Walking Dead. Here is a report from Screenrant.
As for the rumor that horror author Stephen King would be penning an episode for season 2. Darabont responded that King definitely wanted to do it, but it required the presence of his son (and acclaimed author in his own right) Joe Hill – and that their schedules had yet to line-up for the work to progress.
“I’m keeping my fingers crossed. It’s just a matter of… They want to do it together. I’m proud to say that they’re both addicted fans of the show. In fact, Steve started harassing me by email, because I sent him the first one as soon as we had a lab pressing a disc. Like a decent Blu-ray. Then he started harassing me for the next one. Because Joe would drive up from wherever he lives, because he lives an hour away, and they’d sit and watch it together.”
“We’ve literally just been waiting for their schedules, given that they’re pretty in-demand guys. Both of them. We’ve just been waiting for their schedules to mesh. For them to both be free at the same time. That’s the only thing that’s stopping it from happening. It’ll happen eventually, I’m sure.”
