Back in 1996, Kidder disappeared for a few days after experiencing paranoia and was later found in a stranger's backyard.

She was admitted to the Olive View Medical Center and was diagnosed with bipolar disorder. Kidder later explained that her "mood swings could knock over a building.

The acclaimed actress began her career in the late sixties when she landed a role in "The Best Damn Fiddler From Calabogie to Kaladar."

During the first few years in the industry, she also appeared in "Wojeck," "The Dick Cavett Show," and "Banacek."

Kidder soared to fame when she was cast as Lios Lane in "Superman: The Movie" in 1978. She was awarded the Saturn Award for Best Award later that year.

Her last film appearances were as Maggie in "The Neighborhood" in 2017 and as Dr. Amanda Walker in "The Red Maple Leaf" the year before.

Her fans and followers took to social media with Sarah Douglas tweeting: "We continued to have fun together over the last 40 years and she was a joy to be around."

David Axelrod said that Kidder "should be remembered as much for courageously, candidly discussing her battles with mental illness as for any screen role."

‘I decided to keep going, to keep having adventures.’ I wrote this in the @Daily_Record about #MargotKidder at the time of her death. Sad to read about the confirmed cause, but serves to show how far we have to go in effectively treating mental ill-health https://t.co/u9rwCYakWY

She led the way brilliantly.

Kidder, who was married three times, is survived by her daughter Maggie and two grandchildren.
