The Hand That Rocks the Cradle is a 1992 American psychological thriller film directed by Curtis Hanson, and starring Annabella Sciorra, Rebecca De Mornay, Matt McCoy, Ernie Hudson, and Julianne Moore. Its plot follows the pregnant wife of a Seattle obstetrician who kills himself after he is accused of sexual misconduct by his patients. The shock leads the wife to miscarry, after which she poses as a nanny for one of her husband's accusers, and slowly begins to infiltrate the family. The title is taken from an 1865 poem by William Ross Wallace and there are several nods to the comic opera The Pirates of Penzance.

Curtis Lee Hanson was an American film director, screenwriter, and producer. Born in Reno, Nevada, Hanson grew up in Los Angeles. After dropping out of high school, Hanson worked as photographer and editor for Cinema magazine. In the 1970s, Hanson got involved in filmmaking starting with participating in the writing of the horror film The Dunwich Horror (1970) and his directorial debut Sweet Kill (1973), where he lacked creative control to fulfill his vision. While Hanson continued directing, he rose to prominence by being involved in the writing of several critically-acclaimed films. This included Daryl Duke's The Silent Partner (1978), Samuel Fuller's White Dog (1982), and Carroll Ballard's Never Cry Wolf (1983).
