'Superman' actress dies at 69

Margot Kidder, the actress who "found fame" as Lois Lane in the 1978 film "Superman," died on Sunday, May 13, 2018, at her home in Montana.

The actress was 69 years old when she died "peacefully" in her sleep.

According to CNN, "Kidder starred opposite Christopher Reeve's Clark Kent and his alter ego Superman in the original film as well as the three sequels: 'Superman II' in 1980, 'Superman III' in 1983 and 'Superman IV: The Quest for Peace' in 1987."

In 2004, Reeve died from complications of an infection.

In 2016, Kidder said that the chemistry that she had with Reeve was "authentic" because they both came from similar backgrounds; Kidder also said Reeve looked like one of her brothers.

"So the energy we had was one of brother and sister, which was often bickering, that took the place of romantic energy," she said. "No one noticed the difference one from the other -- it worked. We didn't have to create a different reality," Kidder said.

Kidder was born in the Northwest Territories of Canada. She made her first professional acting appearance on the TV series "Wojeck" in 1969.

According to CNN, Hollywood soon reached out to her and gave her the opportunity to appear in more films and television shows: "a move to Los Angeles led to roles on TV shows including 'McQueen,' 'Mod Squad' and 'Nichols.'"

In 1996, Kidder found herself homeless after three marriages and spending thousands of dollars on medical bills, as she struggled with bipolar disorder.

Kidder's story "grabbed the hearts of fans and Hollywood with many reaching out to help." Kidder eventually got herself back on her feet and became a mental health advocate.

Heartfelt tributes to Kidder "poured" out on social media Monday, May 14.

The funeral arrangements for Kidder are pending, according to Franzen-Davis Funeral Home and Crematory in Livingston, Mont.
