We’ve got some sad news to start the week as reports are coming in that Margot Kidder, best known for playing Lois Lane opposite Christopher Reeve in the Superman movies throughout the ’70s and ’80s, has passed away. TMZ is reporting that the Canadian-born actress passed away at her home in Montana yesterday, which has also been verified by the Franzen-Davis Funeral Home. The cause of death is currently unknown but foul play is “not considered a factor.” She was 69 years old.

Kidder got her start on TV in the late ’60s with her first big screen roles coming in Norman Jewison’s 1969 comedy Gaily, Gaily and the Gene Wilder vehicle Quackser Fortune Has a Cousin in the Bronx. She made a name for herself after starring in Brian De Palma 1973 film Sisters in which she played conjoined twins and followed that up with roles in the influential slasher Black Christmas and heist comedy The Gravy Train aka The Dion Brothers. In the latter half of the decade she would be cast in the role that would go on to define her career as Lois Lane in Richard Donner’s Superman.

She also starred opposite James Brolin in the 1979 film The Amityville Horror and throughout the ’80s she appeared in such films as the well-received comedy Heartaches, the Richard Pryor comedy Some Kind of Hero, Disney’s Trenchcoat and Alan Sharp’s Little Treasure starring Ted Danson and Burt Lancaster. In the ’90s she was widely reported to have suffered a nervous breakdown and eventually became a well-known advocate for mental health. More recently she had appeared in Rob Zombie’s Halloween II and won an Emmy for her appearance in an episode of R.L. Stine’s The Haunting Hour. What are your favourite Margot Kidder roles?
