In a statement to the Associated Press, Kidder's daughter Maggie McGuane said the family decided to make her mother's suicide public because "it's important to be open and honest about the suicide so there's no cloud of shame".

According to TMZ, Margot Kidder, the Superman alum, died due to an intentional drug and alcohol overdose.

A joint statement from the coroner's office and her family urged "those suffering from mental illnesses, addiction and/or suicidal thoughts to seek appropriate counselling and treatment".

Now, nearly three months after Kidder's body was found by a friend in her Livingston, Montana home, a coroner there has ruled her death a suicide.

"It's important to be open and honest so there's not a cloud of shame in dealing with this", she continued. At the time, a spokesperson said that the actress passed away peacefully in her sleep. She went on to marry actor John Heard in 1979 only to divorce six days later. But on Wednesday the Park County Coroner's Office in Montana, where she lived, revealed that the cause was suicide.

She told AP: "It's a very unique sort of grief and pain".

Margot Kidder rose to fame in the 1970s starring as Lois Lane alongside the late Christopher Reeve in Richard Donner's Superman.

And she was known for her work as a mental-wellness advocate, in part because of her own struggles with mental health.

Regarding her family life, Kidder got married three different times throughout her life and has one daughter, Maggie McGuane. In one of her final interviews, with the pop culture site Hey U Guys in 2016, Kidder said that she never anticipated the success of the Superman film and was unprepared for the instant worldwide stardom that it brought to her.
