A Good Marriage is based on Stephen King‘s novella from the Full Dark, No Stars collection, and it’s the first King screenplay to hit the big screen in a long time. The film stars Joan Allen, Anthony LaPaglia, Kristen Connolly, and Stephen Lang in a story about a woman who discovers that her perfect, loving husband is in fact a serial killer. Nice concept, but this first A Good Marriage trailer shows that it might falter in the execution. Check it out below. So… yeah.
