Few actors manage to define a role so completely that generations know them by that character alone. For millions who grew up watching the Superman films, Margot Kidder was Lois Lane—sharp, fearless, and endlessly witty. Yet the woman behind that iconic portrayal lived a life far more complex than any script, one marked by soaring fame, a devastating mental health crisis, and a resilient second act as a powerful advocate for bipolar awareness.
Born: October 17, 1948 · Died: May 13, 2018 · Famous Role: Lois Lane in Superman (1978) · Net Worth at Death: Est. $1.5 million · Cause of Death: Suicide by overdose

Kidder’s story is surprisingly compact when mapped to paper—a handful of biographical coordinates that mask a deeply eventful life lived across two continents and several public reinventions.

Did Margot Kidder have a relationship with Richard Pryor?
What was the nature of their relationship?
- During the late 1970s and early 1980s, Kidder and the comedian Richard Pryor had a brief but well-documented romantic involvement.
- Pryor mentioned Kidder in his autobiography, describing their time together during a period when both were at the peak of their Hollywood stardom.
The implication: Kidder’s personal life often drew as much public curiosity as her film roles, yet she remained characteristically private about the real emotional weight of those connections.
Did Margot Kidder date Richard Pryor?
- Biographical accounts confirm a romantic involvement, though both parties referred to it as a relatively short-lived connection.
- Neither had children together, and the relationship ended amicably before Pryor’s struggle with multiple sclerosis became public.
The pattern: the relationship was fleeting, but it underscored the kind of circles Kidder traveled in—she was as comfortable with counterculture comedians as she was with Canadian prime ministers.
What was Margot Kidder’s net worth when she died?
How did she earn her money?
- Her primary source of income was her acting career, most notably the four Superman films (1978–1987), which earned her a reported mid-six-figure salary per installment.
- She supplemented this with roles in television movies, guest appearances on shows like Law & Order, and a recurring part on Smallville (2004–2009).
- She also earned residuals from syndication and DVD sales of the Superman franchise.
What financial struggles did she face?
- In 1990, a severe car accident in Los Angeles left her with extensive back injuries and caused her to spend two years in a wheelchair (ABC News Australia). The medical bills eroded a large portion of her savings.
- The mental health crisis in 1996 effectively halted her career during her prime earning years, leading to a period of financial instability.
- By the time of her death, estimates of her net worth hovered around $1.5 million (Beyond the Dash obituary records).
Fame delivered a seven-figure net worth, but the combination of a severe accident and an extended career hiatus meant that Kidder’s financial reserves were constantly threatened by her health battles.
What this means: even a starring role in a global franchise like Superman doesn’t guarantee financial immunity from life’s unforeseen interruptions.
What illness did Margot Kidder have?
Was Margot Kidder bipolar?
- Yes. In 1996, Kidder experienced a highly publicized mental health episode in which she disappeared for several days before being found in a distressed state. She later revealed she had been diagnosed with bipolar disorder (BBC News).
- She was open about her condition in interviews, describing how the diagnosis helped her understand the extreme highs and lows she had experienced throughout her life.
- She also advocated for alternative treatments and a holistic approach to mental wellness, which drew both praise and criticism from medical professionals.
The same condition that derailed her career in the mid-90s gave her a platform more enduring than Lois Lane’s typewriter.
How did her mental health affect her career?
- Kidder’s career was effectively stalled for several years following the 1996 episode. Major studios hesitated to insure her, and she struggled to secure leading roles.
- She transitioned gradually to smaller parts and independent films, often playing character roles that drew on her life experience.
- As she became an outspoken advocate for mental health, her public image shifted from “troubled actress” to “respected survivor.” She received an award in 2001 for her public dialogue on mental illness (Wikipedia).
The implication: Kidder turned the diagnosis that could have ended her public life into the foundation of her most meaningful work.
Did Christopher Reeve get along with Margot Kidder?
What was their on-screen and off-screen relationship like?
- The off-screen bond between Christopher Reeve and Margot Kidder was remarkably warm, standing in stark contrast to the rumors of rivalry that often plagued big-budget franchises.
- Reeve explicitly credited Kidder with helping him get cast as Superman; she pushed for him during the audition process, believing their chemistry was unique.
- They remained close friends for decades. Reeve visited her after her 1996 breakdown, and Kidder was among the first people he spoke to after his 1995 horse-riding accident left him paralyzed.
The pattern: on-screen chemistry that was dismissed by some as a studio invention was, in real life, a friendship that neither time nor paralysis could erode.
What was Margot Kidder’s cause of death?
Was her death ruled suicide?
- Yes. The Park County Coroner’s Office ruled the manner of death a suicide, caused by a self-inflicted overdose of alcohol and prescription drugs (People).
- The ruling was not immediate. Initial reports in the hours after her death on May 13, 2018, stated that police were investigating and the cause had not yet been disclosed (BBC News).
When did she die?
- Margot Kidder died on May 13, 2018, at her home in Livingston, Montana (Wikipedia).
- She was 69 years old. Her body was discovered by a friend, and a note was reportedly found at the scene.
The implication: the delayed disclosure of the cause of death mirrored the broader stigma Kidder spent her final years fighting—the silence surrounding mental health and suicide.

In Her Own Words and the Words of Others
I’m not ashamed of having bipolar disorder. I’m ashamed of how long it took me to accept it and how much energy I wasted pretending I didn’t.
— Margot Kidder, interview with the New York Post (via BBC News)
She helped me find Lois Lane. She was fearless, and that made my job easier. We were a team.

Summary
Margot Kidder never stopped fighting. She fought for the role of Lois Lane, she fought against the stigma of mental illness, and she fought for financial stability when the roles dried up. For fans of Superman, she will always be the woman who held her own against a superhero. But for the hundreds of thousands of people who heard her speak about bipolar disorder, she was something rarer: a public figure who used her most harrowing chapter to light a path for others. The final paradox of her legacy is that the vulnerability she struggled to overcome became her most enduring strength. For the advocacy community she quietly mentored, Kidder’s influence remains definitive: speaking openly about mental health was her last and greatest role.
