Psychological thriller will mark his big screen debut.

It has been announced that British television director Andy Goddard (‘Downton Abbey,’ ‘Dr.Who,’ ‘Hex,’ ‘Wire in the Blood’) is to make his feature debut with the psychological thriller ‘The Blunderer.’

Adapted from by Susan Boyd from Patricia Highsmith’s 1954 novel of the same name, the story follows the young, successful and handsome, Walter Stackhouse who seems to have it all, that is, until the day his wife’s body is found at the bottom of a cliff. Under the intense scrutiny of the investigation he commits one mistake, then another, until – in true Highsmithian fashion – Walter finds his perfect life derailed. Now Walter is running from the obsessions of the murderer, and the suspicions of the lead cop, not to mention his own increasingly life-threatening blunders.

Ted Hope and Killer Films’ Christine Vachon will produce the project along with Sierra Pictures. In a statement announcing the adaptation, Hope commented, “’The Blunderer’ is a modern day Hitchcock doled out with a healthy dose of today’s sexuality and violence, but told with the wit, cunning, and drama that makes Andy the perfect choice for his feature film debut.”
