Late Superman actress Margot Kidder’s death has been ruled as a suicide, a medical coroner said Wednesday.

The coroner’s statement said Kidder, who was found dead at age 69 in her Montana home on May 13, “died as a result of a self-inflicted drug and alcohol overdose.” No additional information on her death has since been made available.

Kidder played female protagonist Lois Lane alongside Christopher Reeve in the Superman movies of the 1970s and 1980s.

“It’s a big relief that the truth is out there,” the actress’s daughter Maggie McGuane said about her mother’s suicide. “It’s important to be open and honest so there’s not a cloud of shame in dealing with this.”

McGuane also emphasized the importance of people with mental illnesses seeking treatment, given the high rate of suicides in the country.


Kidder’s suicide preceded those of two other major celebrities who died in June: fashion designer Kate Spade and chef Anthony Bourdain.

Kidder reportedly had a history of mental heath problems. In 1990, she was also involved in a car accident. She opened up about her bipolar disorder and mood swings in a 1996 interview with People magazine.

The actress’s other film credits included Brian De Palma’s Sisters in 1973 The Great Waldo Pepper with Robert Redford in 1975 and The Amityville Horror in 1979.

Kidder continued acting in films until 2017 and also won a Daytime Emmy Award in 2015 for Outstanding Performer in a kids’ series for her appearance on an episode of Discovery Family’s R.L. Stine’s The Haunting Hour.
