Another story from the master of horror, Stephen King, has been adapted into a feature film. A Good Marriage is based on a novella that was part of King's Full Dark, No Stars short story collection. The script for the film was also written by King.
The story follows a happily-married, middle-aged couple who seem to have spent a perfect life together. Then one day the wife (Joan Allen) finds evidence indicating that her husband (Anthony LaPaglia) is a serial killer whose crimes have gone unpunished.
I've read the story and it's really good. There's a lot of heavy suspense in it, and it looks like that suspense has carried over into the movie.
The film co-stars Kristen Connolly and Stephen Lang and is set to be released on October 3rd.
