A Reflection of Fear is a 1972 American horror thriller film directed by William A. Fraker with a screenplay by Edward Hume and Lewis John Carlino and starring Sondra Locke, Robert Shaw, Mary Ure, Signe Hasso, Gordon Devol and Sally Kellerman.

The film is set in an alienated mansion in Eastern Canada that houses Marguerite, 15, the main protagonist, her mother Katherine and her maternal grandmother, Julia.

Marguerite suffers from what appears to be paranoia as is apparent when she is shown talking to her dolls, especially one named Aaron or an amoeba collected from a pond, or painting unsettling pictures in seclusion.

Out of the blue, she expresses her yearning to connect with her father, Michael, a writer, who was estranged from the family for a decade and is now in a relationship with a woman named Anne.

In time, Marguerite's affection for her father turns inordinate and her sense of insecurity escalates as she is seen spying on the members of the household through crevices.

As the attacker tries to escape through the crawl spaces of the home, it revealed to be Marguerite in the personality of Aaron, who repeatedly assaults Michael as he continues the pursuit.

"[5] In his review on DVD Talk, Paul Mavis writes, "there's no getting around the fact that much of A Reflection of Fear flat-out doesn't make sense.
