Margot Kidder: Biography, Death, Net Worth, Relationships

It’s a quiet irony that an actress best known for playing a fearless newspaper reporter ended up fighting a different kind of cover-up — the stigma around mental illness. Margot Kidder, who brought Lois Lane to life in the Superman films, faced her own battles with bipolar disorder and public scrutiny before her death in 2018 at age 69.

Born: October 17, 1948 ·
Died: May 13, 2018 ·
Known for: Lois Lane in Superman films ·
Cause of death: Suicide by barbiturate overdose ·
Number of films: Over 50 ·
Nationality: Canadian-American

After the Superman spotlight faded, Kidder’s career took a quieter turn — but her most lasting work may have been the one she never auditioned for: mental health advocacy.

The following table consolidates the key factual snapshot of her life.

Did Christopher Reeve like Margot Kidder?

“He was the most wonderful man.”
— Margot Kidder on Christopher Reeve, 2004 interview

Margot Kidder and Christopher Reeve shared a close, platonic friendship that lasted long after the Superman cameras stopped rolling. Reeve, who portrayed Clark Kent, and Kidder, as Lois Lane, developed a bond that the actress described as built on mutual respect and genuine affection. In a 2004 interview, Kidder called Reeve “the most wonderful man” (GrokNation, mental health–focused outlet). There has never been evidence of a romantic relationship between them; their connection was one of deep professional and personal kinship.

What did Margot Kidder say about Christopher Reeve’s death?

• Kidder expressed profound sadness at Reeve’s death in 2004 (GrokNation)
• She said that Reeve “showed more courage in ten years than most people do in a lifetime” (The New York Times)

The pattern is clear: for both actors, the Superman set was the start of a lifelong friendship that neither fame nor tragedy could break.

Was Jane Seymour in love with Christopher Reeve?

Jane Seymour, who starred with Reeve in Somewhere in Time (1980), has never publicly claimed to be “in love” with him in a romantic sense. Rumours occasionally surface, but no credible source confirms a relationship beyond mutual admiration (Wikipedia). The Kidder–Reeve connection remains the most documented off‑screen tie from the Superman era.

The catch: while the public often wants a love story, Kidder and Reeve’s friendship was arguably more remarkable — a bond that outlasted the limelight.

Did Margot Kidder date Trudeau?

Yes — Margot Kidder dated Pierre Trudeau, then Prime Minister of Canada, in the 1970s. The relationship was widely reported at the time and is confirmed by multiple sources, including Wikipedia and biographical accounts. Kidder was a young rising actress when the two were seen together at social events, though neither party offered extensive public commentary on the affair.

What was the relationship between Margot Kidder and Richard Pryor?

• Kidder and comedian Richard Pryor had a brief romantic relationship in the 1970s (Wikipedia)
• Pryor, who co‑starred with Kidder in the 1976 film Car Wash, was known for his turbulent personal life
• Little detailed information exists about the timeline or duration of their relationship

Why this matters: Kidder’s romantic life was often sensationalised, but the relationships with Trudeau and Pryor reflect her immersion in the celebrity culture of the 1970s — a world that could be as isolating as it was glamorous.

Did Margot Kidder have any children?

Yes — Kidder had one daughter, Maggie McGuane, born in 1976. McGuane, who now lives in Montana, has spoken publicly about her mother’s death and her mother’s legacy as a mental health advocate (CBS News).

The implication: Kidder’s role as a mother was overshadowed by her Hollywood image, but Maggie’s quiet advocacy keeps her mother’s story alive.

What did Margot Kidder suffer from?

Margot Kidder suffered from bipolar disorder, a condition she was diagnosed with in the late 1990s after a very public breakdown in 1996. The actress later became one of Hollywood’s most outspoken advocates for mental health awareness, using her own story to fight the stigma she had once feared.

How did Margot Kidder lose her teeth?

• Kidder lost several teeth as a side effect of the medication she took for bipolar disorder (GrokNation)
• She had to undergo extensive dental surgery, which she discussed in interviews to highlight the physical toll of mental health treatment

The trade‑off: treating a psychiatric condition with powerful drugs can bring relief, but also unexpected — and sometimes disfiguring — consequences. Kidder bore them publicly.

Was Margot Kidder found hiding in the bushes?

In April 1996, Kidder was discovered hiding in the bushes of a Los Angeles neighbourhood after a manic episode that triggered a period of homelessness. She had stopped taking her medication, partly because of side effects, and a computer virus added to her paranoia (CBS News). The episode became tabloid fodder, but Kidder later owned it as a teachable moment. “After it was over, I totally understood the need to abolish the stigma attached to people with thought disorders,” she said (GrokNation).

What this means: the image of a Hollywood star sleeping in the bushes could have been the end of her story. Instead, it became the beginning of a new chapter — one where she reclaimed her narrative.

What was Margot Kidder’s net worth when she died?

At the time of her death in 2018, Margot Kidder’s net worth was estimated to be around $500,000 — a modest sum for a star of her stature (Wikipedia). She faced significant financial difficulties later in life, including medical bills and reduced acting income. The exact figure is difficult to pinpoint because her estate was not publicly itemised, but the number reflects a career that peaked decades earlier and a life lived without excessive wealth accumulation.

The pattern: Kidder’s net worth is a sharp contrast to the millions earned by many of her peers — a reminder that fame does not guarantee fortune, especially when health crises drain resources.

Are Margot Kidder and Courteney Cox related?

No, Margot Kidder and Courteney Cox are not related. The surname similarity — “Kidder” and “Cox” — is coincidental. Cox, known for Friends, has no family link to the Canadian‑American actress. The rumour likely arose from the confusion of two actresses with short, uncommon names (Wikipedia).

The catch: the internet loves a family‑tree conspiracy, but sometimes a coincidence is just a coincidence.

What has happened to Margot Kidder?

Margot Kidder died on May 13, 2018, in Livingston, Montana. The Park County coroner ruled her death a suicide by self‑inflicted barbiturate and alcohol overdose (CBS News). She had been scheduled to appear at Motor City Comic Con later that same week (Wikipedia). Her daughter Maggie McGuane said she knew her mother had died by suicide when authorities came to the home (CBS News).

The implication: Kidder’s death was a tragedy that cut short a life of advocacy, but her story continues to resonate — especially for those who struggle with the same disorder she fought to destigmatise.

Margot Kidder’s life encapsulates a paradox: the woman who flew as Lois Lane was grounded by a condition that needs no cape to be understood. For today’s fans and advocates, the choice is clear: remember her not only for the red‑carpet smile but for the courage to speak about what lay behind it — because silence, in the end, is the deadliest cover‑up.
