Born in Yellowknife in Canada's Northwest Territories in 1948, Margo Ruth Kidder, spent the early years of her life moving with her family because of her engineer father's career. Reeve passed away in 2004 at the age of 52.
She hosted "Saturday Night Live", appeared with Christopher Reeve at the Oscars, and had a friendship with a Canadian prime minister. Kidder portrayed Lois Lane and McClure played Jimmy Olsen in the film which also starred Christopher Reeve as Superman.
She'd been married 3 times, although she'd been single since the '80s. She also featured in such films as Black Christmas (1974) and Heartaches (1981).
Kidder had a debilitating auto accident in 1990 that left her badly in debt, confined her to a wheelchair for most of two years and worsened the mental illness she had struggled with for much of her life.
The starlet also had starring roles in 1975 drama The Great Waldo Pepper and 1979 thriller The Amityville Horror. She had banked a 10-year body of work in TV and movies by the time "Superman" arrived.
She scored the coveted role of Superman's paramour Lane in 1976 after a lucky call earned her a screen test in front of director Richard Donner.
She is survived by her daughter, Maggie McGuane.
And in 2015 Kidder won an Emmy award for Outstanding Performer in Children's Programming for her performance in RL Stine's The Haunting Hour. After an infamous breakdown on the streets of Los Angeles in 1996, Margot Kidder credited a homeless man with showing compassion for her and saving her life during her "big, public flipout".
