Stephen King may be one of our most prolific writers, but he tends to let others get the ol’ finger blisters when it comes to adapting his tales for the big screen. One exception? The forthcoming, Peter Askin-directed A Good Marriage, for which Uncle Stevie did decide to pen the screenplay version of his novella.

“I knew Peter Askin and I liked him,” King recently told EW, explaining the origin of the project. “About a thousand years ago, John Mellencamp and I got involved with this musical called Ghost Brothers of Darkland County. We didn’t know anything about musicals, and Peter, who has directed Hedwig and the Angry Inch, came on board for the workshop. I bonded with him and at some point I said, ‘Would you like to do a movie with me?’ I had something in mind. So we worked on it and finally we both knew [we had something]. We went in fearlessly and this is what we came up with.”

A Good Marriage stars Joan Allen, Anthony LaPaglia, Stephen Lang, and House of Cards actress Kristen Connolly, and it concerns a terrible family secret. I’ll say no more—except to point out that the film is released in cinemas and on VOD Oct. 3—and that you can see both the movie’s trailer and an exclusive clip below.
