She also recalled that she began her quest to get the role by making sure the producers know that she was really in love with Superman even if she thought that Reeve was the "skinniest dorkiest guy you could imagine".
Her sister said the actress treasured some of the smaller roles she had later in her life.
Superman director Richard Donner said that Kidder was "charming and very amusing".
Recalling how a data retrieval company couldn't rescue her work, Margot told the publication: "That's when I went from really distressed to absolute delusion".
"I just kind of admired her strength". She was a true class act and will be very missed. During that time, the actress, who was diagnosed with bipolar disorder, went into a manic state and disappeared for four days with her teeth deliberately knocked out.
"So saddened by the news that dear #MargotKidder has died peacefully in her sleep yesterday", Douglas wrote.
But all was not easy for her and for her Superman. A veteran of both TV and motion pictures, Kidder moved on to that great place beyond at 69 years old. "For most of my life since then, that's been the Lois Lane character".
Several Hollywood personalities took to Twitter to express their sadness over Kidder's death.
The official handle of DC Comics tweeted, "Thank you for being the Lois Lane so many of us grew up with". Her career crested in the ´70s and ´80s, as she worked with film stars including Robert Redford and Richard Pryor. "We continued to have fun together over the last 40 years".
She was especially popular playing the role opposite Christopher Reeve in "Superman" in 1978, "Superman II - Alone Against All" in 1980, "Superman III - The Steel Lightning" in 1983 and "Superman IV - The World on the Edge" in 1987.
"She led the way brilliantly", Hatcher wrote.
"On-screen she was magic". She has featured in more than 70 TV Shows and movies.
