Margot Kidder, who catapulted to Hollywood fame in the late '70s as Lois Lane in the "Superman" movies, has died, according to the Montana funeral home handling her arrangements.
Brandon Routh, who portrayed Superman in 2006's Superman Returns, also hailed Kidder for openly discussing her own battles with mental health.
Superman was a superhero blockbuster two decades before comic book movies became the norm at the top of the box office.
It is cited as an essential inspiration by makers of modern day Marvel and DC films.
Co-creator of several Marvel characters, Brian Michael Bendis, remembered the actor and wrote, "I rewatched all the superman the movie extras when we were prepping on powers and Margot Kidder's audition is a ideal moment for the flawless actor".
In the post, writer and indie film director Ted Geoghegan revealed Margot had a very unusual request for what she wanted to happen to her body. I'll miss you Margo Kidder.
While Margot Kidder died on Sunday night, the original Superman, Christopher Reeves breathed his last in 2004, and with the death of duo, it's indeed an end of an era.
Kidder also had a small part in 1975s The Great Waldo Pepper with Robert Redford, and starred as conjoined twins in Brian de Palma's 1973 Sisters, and as the mother of a terrorized family opposite James Brolin in 1979s The Amityville Horror. With her citizenship, Kidder was an activist and challenged the Iraq War. There was only one true Margot Kidder.
While there hasn't been any public documentation on the cause of death, it was reported she passed away at the age of 69, in her Montana home. They made her what used to be the girlfriend, which kind of ended in the 60s with women's rights.
"I don't act much anymore unless I'm broke, and then I'll take a job", she told the Detroit radio station with a laugh. A spark of vivacious life in all of her films.
She was married and divorced three times and is survived by her only child, daughter Maggie, and three children.
