Amy Adams and Jake Gyllenhaal star in Nocturnal Animals

In case you haven't heard, Nocturnal Animals starring Amy Adams & Jake Gyllenhaal is set for release December 9th. The film, directed by designer Tom Ford (A Single Man) is based on the book, Tony & Susan by Austin Wright.To complicate matters, Amy Adams look alike Isla Fisher is playing Laura Hastings, Tony's wife, while Amy plays Susan Morrow—Tony's ex.

Here's the movie's logline:

An art gallery owner is haunted by her ex-husband's novel, a violent thriller she interprets as a veiled threat and a symbolic revenge tale.

And the overview of the book:

Fifteen years ago, Susan Morrow left her first husband Edward Sheffield, an unpublished writer. Now, she's enduring middle class suburbia as a doctor's wife, when out of the blue she receives a package containing the manuscript of her ex-husband's first novel. He writes asking her to read the book; she was always his best critic, he says. 

As Susan reads, she is drawn into the fictional life of Tony Hastings, a math professor driving his family to their summer house in Maine. And as we read with her, we too become lost in Sheffield's thriller. As the Hastings' ordinary, civilized lives are disastrously, violently sent off course, Susan is plunged back into the past, forced to confront the darkness that inhabits her, and driven to name the fear that gnaws at her future and will change her life.
