I Know Who Killed Me is a 2007 American psychological thriller film directed by Chris Sivertson, written by Jeff Hammond, and starring Lindsay Lohan, Julia Ormond, Neal McDonough and Brian Geraghty. The film's story revolves around a young woman who is abducted and tortured by a sadistic serial killer. After surviving the abduction, she insists that her identity is that of another woman.

Lindsay Dee Lohan is an American actress, singer-songwriter, producer, and entrepreneur. Born in New York City and raised on Long Island, Lohan was signed to Ford Models at age three. She appeared as a regular on the soap opera Another World at the age of 10, and her breakthrough came in the 1998 Walt Disney Pictures film The Parent Trap. The film's success led to appearances in subsequent Disney projects; the television films Life-Size (2000) and Get a Clue (2002) and the big-screen productions Freaky Friday (2003) and Confessions of a Teenage Drama Queen (2004). Lohan's early work won her childhood stardom, while the teen comedy sleeper hit Mean Girls (2004) affirmed her status as a teen idol and established her as a leading Hollywood actress.
