The bestselling author coyly suggested that more than one movie might be in the works.

Stephen King is making the rounds lately to talk about "A Good Marriage," the new movie based on his novella about a devoted husband with a sinister secret. But when he stopped by MTV to discuss that film, we couldn't resist the chance to also get some details on another King adaptation in the works: the hotly-anticipated "The Stand," which is coming to the big screen courtesy of "The Fault in Our Stars" director Josh Boone.

Not only is Boone taking on an enormous responsibility in "The Stand" -- including adapting the script himself from King's 1,000-plus-page novel -- but rumor has it that he plans to contain the entire story in just one film, an astronomical challenge considering how sprawling it is.

Fortunately, Stephen King has nothing but faith in the director's ability to bring "The Stand" to life. In fact, he's so in tune with Boone's process that he even dropped a tantalizing hint about those "single movie" rumors.

"I think that his take is terrific -- and don't count on it being one film," King said.

What does that mean?! Unfortunately, the author wouldn't say much more about it, only going so far as to tell us, "There's talk about doing it in an entirely different and innovative way, and I don't want to go into it because that's Josh's baby."

But whatever Boone's secret mystery plans, King is clearly confident that his work is in good hands.

"He made 'The Fault in Our Stars,' which is Class A filmmaking as far as I'm concerned," the author said. "He's hugely ambitious and hugely energetic, so we'll see what happens."

"The Stand" won't be in theaters for another few years, most likely -- but Stephen King fanatics in need of a fix can catch "A Good Marriage" in theaters and on demand starting October 3.
