Playing a widow devoted to the grown son (Johnathon Schaech) who brings his fiancee (Gwyneth Paltrow) back to his family’s Kentucky estate, Jessica Lange establishes a spark of interest in this psychological thriller with her giggly demonic performance. But the film never adds up to anything more than an elaborate tease; the writing and directing of Jonathan Darby, a British TV veteran and Hollywood executive, make the proceedings neither believable nor compelling, so what might have been another Rosemary’s Baby isn’t even a halfway decent genre exercise. With Nina Foch, Debi Mazar, and Hal Holbrook; cowritten by Jane Rusconi. (JR)
