THE HAND THAT ROCKS THE CRADLE opens. Directed Curtis Hansen, from a screenplay by Amanda Silver. Rebecca De Mornay is aces as an embitted young woman who, under the guise of a nanny, unleashes a concerted terror campaign against the yuppie couple she holds responsible for the suicide death of her husband and her own subsequent miscarriage. Tightly wound urban thriller persuasively elbows its escalating methodic mayhem toward a gangbuster finale. Co-starring Annabella Sciorra, Matt McCoy, Julianne Moore and Ernie Hudson. Film tops box office for four consecutive weeks.
