Her other notable film credits include "Sisters," "Black Christmas," "The Great Waldo Pepper," and "The Amityville Horror." After going through a publicized nervous breakdown in the 1990s, Kidder returned to acting with guest roles on such television series as "Smallville" and "The L Word."

Margot Kidder was born Margaret Ruth Kidder on October 17, 1948, in Yellowknife, Northwest Territories, Canada. She was the daughter of history teacher Jill and explosives engineer Kendall. Her mother was Canadian, while her father was American; she had a sister named Annie and three brothers named John, Michael, and Peter. Kidder developed an interest in both show business and politics from an early age. She also struggled early on with her mental health, only later learning she had undiagnosed bipolar disorder. Margot went to a number of schools throughout her youth due to her family's many moves around the country; she ultimately graduated from Havergal College in 1966. That year, Kidder had an illegal abortion after becoming pregnant by her boyfriend. For her higher education, she attended the University of British Columbia for a year before dropping out.

In 1968, Kidder made her film debut in "The Best Damn Fiddler from Calabogie to Kaladar," which was produced by the Canadian participatory film and video project Challenge for Change. Following this, she appeared in the comedy "Gaily, Gaily." Margot next starred oppositeGene Wilderin the 1970 comedy "Quackser Fortune Has a Cousin in the Bronx." She returned to the big screen in 1973 to star inBrian De Palma'sacclaimed psychological horror film "Sisters," in which she played conjoined twins. The year after that, Kidder was in three films: the drama "A Quiet Day in Belfast," the crime comedy "The Gravy Train," and the slasher film "Black Christmas." She was in three more films in 1975: the dramas "The Great Waldo Pepper" and "92 in the Shade" and the psychological horror film "The Reincarnation of Peter Proud."

Later in life, Margot drew more attention to herself when her (later diagnosed) illness of a bipolar condition sent her on a downhill spiral. In April 1996, she disappeared for a time and began living on the street. She was found in a backyard by a homeowner and taken by Los Angeles police to Olive View Medical Center in a distressed state. The caps on her teeth had even fallen out (or were possibly taken out to disguise herself, as proposed by the media at the time). She was later placed in psychiatric care. In 2007, Kidder said she had not had a manic episode in 11 years. She had been diagnosed with bipolar disorder early in her life.
