Margot Kidder, who played Kathy Lutz in The Amityville Horror (above), released in 1979, took her own life her daughter told the Associated Press. Maggie McGuane said Kidder’s death had been ruled a suicide, adding that she knew her mother had killed herself when she was brought to the actress’ Montana home in May.
Park County coroner Richard Wood said Kidder died “as a result of a self-inflicted drug and alcohol overdose.” Kidder died May 13 at the age of 69. Her manager, Camilla Fluxman Pines, told TheWrap the actress died peacefully in her sleep.
Born in Canada in 1948, Kidder appeared in a number of low-budget Canadian films and TV shows. In addition to The Amityville Horror, she appeared in several movies including the 1973 thriller Sisters and the Robert Redford-drama The Great Waldo Pepper . She also played the part of Lois Lane in Superman (1978), starring Christopher Reeve, and its sequels.
Kidder’s career and personal life suffered setbacks in the 1990s, following a nervous breakdown. She disappeared for four days in 1996 and later told People magazine, “I was like one of those ladies you see talking to the space aliens on the street corner in New York.” She admitted she was a manic-depressive and claimed she had “mood swings that could knock over a building.”
However, the actress later enjoyed a career revival, guest-starring on Smallville, Brothers & Sisters and The L Word. She earned an Emmy in 2015 for her work on the children’s series R.L. Stine’s The Haunting Hour.
