Margot Kidder

Margaret Ruth Kidder was a Canadian-American actress and activist whose career spanned five decades. Born in Yellowknife, Northwest Territories, to an American father and a Canadian mother, she navigated a nomadic childhood across the Canadian wilderness before establishing herself in New York City. Her journey began in the mid-1960s with small roles in Canadian television, leading to early recognition with a Special Award from the Canadian Film Awards in 1969. She stood approximately 5'8" (173 cm) tall, known for her distinctive blonde hair and expressive eyes.

Kidder achieved international fame in 1978 when she portrayed Lois Lane opposite Christopher Reeve in Richard Donner's Superman. The film became a massive cultural phenomenon, and she won a Saturn Award for Best Actress for her performance. She reprised the role in three sequels: Superman II, Superman III, and Superman IV: The Quest for Peace. During this period, she also starred in the blockbuster horror film The Amityville Horror alongside James Brolin. Beyond acting, Kidder was known for her activism regarding political, environmental, and antiwar issues. Despite facing personal challenges, including a car accident in 1990 and a highly publicized manic episode in 1996 related to bipolar disorder, she continued working steadily in independent films and television until her death in 2018.

Margaret Ruth Kidder arrived in Yellowknife on October 17, 1948, to a family split between Canada and the United States. This professional arrangement required the family to move frequently, so Kidder spent her formative years traveling between the Northwest Territories, Alberta, and British Columbia before settling in Calgary. She attended high school in Calgary and later studied at the University of Alberta, though she eventually left formal education to pursue acting in New York City in the late 1960s. Before achieving widespread recognition, Kidder built her resume through small roles in Canadian television and low-budget productions. Her first major breakthrough came in 1969 when she earned a Special Award from the Canadian Film Awards for her performance in The House That Would Not Die. Early in her career, she appeared in diverse genres, showcasing her versatility. She played roles in the comedy Quackser Fortune Has a Cousin in the Bronx (1970), the psychological thriller Sisters (1972), and the horror classic Black Christmas (1974). These early projects established her reputation as a capable performer who could handle both light and dark material, setting the stage for her eventual Hollywood breakthrough. [edit]
