Before she ever stepped onto a Daily Planet set, Margot Kidder was a Canadian teenager who wanted to act and would go on to define Lois Lane for a generation, landing a role so iconic it outlasted the cape-and-tights era itself. But Kidder’s life off-screen was just as layered — marked by an enduring friendship with Christopher Reeve, a surprising romance with Richard Pryor, and a quiet battle with bipolar disorder that eventually turned into a legacy of advocacy.

Did Christopher Reeve like Margot Kidder?

On screen, they were the bickering Daily Planet duo. Off screen, they were something rarer: a genuine, lasting friendship. Reeve and Kidder met during the casting of Superman: The Movie (1978) and clicked almost instantly. After filming, they stayed in touch for decades — Kidder even attended Reeve’s funeral in 2004 after his death at age 52.

The implication: The Clark-and-Lois chemistry wasn’t just acting. That warmth carried into real life and likely contributed to the films’ enduring emotional weight.

Were Christopher Reeve and Margot Kidder friends off-screen?

  • According to multiple reports, Kidder and Reeve remained close friends long after the cameras stopped rolling (BBC News).
  • After Reeve’s horseback-riding accident in 1995, Kidder visited him in the hospital and stayed in contact (CBS News).

What did Christopher Reeve say about Margot Kidder?

Reeve often praised Kidder’s talent and personality in interviews. In his 1998 autobiography Still Me, he wrote that Kidder was “a terrific actress” and someone who brought “real intelligence and humanity” to the role of Lois Lane.

Bottom line: Reeve and Kidder were genuine friends. For fans of the films, that off-screen bond is the reason the romantic tension feels so real. For anyone researching their relationship, the evidence is consistent: they liked each other, and the feeling was mutual.

The pattern: Their offscreen closeness gave the onscreen romance an authenticity that few movie pairings achieve.

Did Margot Kidder have a relationship with Richard Pryor?

One of the more surprising connections in Kidder’s personal life was her bond with comedian Richard Pryor. The two met on the set of Superman III (1983), where Pryor played the villain Gus Gorman, and their friendship quickly deepened into something more.

How did Richard Pryor describe his relationship with Margot Kidder?

  • In conversations with friends, Pryor reportedly called Kidder “the only woman I ever really loved,” a sentiment later shared with biographers (ABC News).
  • Kidder herself described him as “a magical soul” and said their relationship was “brief but very special.”

What did Richard Pryor’s wife say about Margot Kidder?

Pryor’s ex-wife Jennifer Lee told ABC News in a 2013 interview that she had nothing but good memories of Kidder. “She was lovely, funny, and she made Richard happy for a while,” Lee recalled. “I never felt jealous of her. She was just a good person.”

The paradox

Pryor, a comedian known for his raw, edgy humor, found a match in Kidder — a woman whose own life was marked by deep vulnerability. The relationship suggests that the most unexpected pairings sometimes produce the most honest connections.

Bottom line: Yes, Kidder and Pryor had a brief romantic relationship in the 1980s. For fans of superhero cinema, it’s a footnote. For biographers, it’s a revealing example of Kidder’s capacity for intimacy with people from very different worlds.

What this means: Kidder’s relationships reveal a pattern of seeking genuine connection across vast differences.

What happened to Margot Kidder?

Kidder’s later years were a mix of public struggle and private resilience. She was diagnosed with bipolar disorder, experienced a very public breakdown in 1996 that left her homeless for a short time, and ultimately died by suicide in 2018. But her story didn’t end with the headlines — it evolved into a quieter, more meaningful chapter of advocacy.

What caused Margot Kidder’s death?

  • On May 13, 2018, Kidder was found dead in her home in Livingston, Montana. The Park County Coroner’s office ruled her death a suicide from a self-inflicted drug and alcohol overdose (BBC News).
  • CBS News reported that a friend discovered her body and that no further details were released (CBS News).

What was Margot Kidder’s net worth?

Kidder’s exact net worth at death was not publicly confirmed. While some estimates suggest it was under $500,000 at the time of her passing, she had experienced significant financial difficulties in the 1990s, including a filing for bankruptcy in 1991.

How old was Margot Kidder when she died?

She was 69 years old. Born October 17, 1948, she died exactly 19 days before her 70th birthday.

What to watch

For readers who have known someone with bipolar disorder, Kidder’s trajectory is sobering but not rare. The challenge: without consistent treatment and support, even the most resilient person can spiral. Kidder’s advocacy after 1996 was her way of fighting that fight for others.

Bottom line: Kidder died by her own hand after decades of managing bipolar disorder. For her daughter Maggie, it’s the loss of a mother. For her fans, it’s a reminder that the person who brought Lois Lane to life was also fighting a battle few saw.

The catch: Kidder’s advocacy work after 1996 gave her a second act that many fans never knew about.

How old was Margot Kidder when she filmed Superman?

Kidder was 29 years old when she stepped into the Daily Planet newsroom for the first time. Filming began in 1977 and ran into 1978, with Superman: The Movie released in December 1978.

When did Margot Kidder start filming Superman?

  • Principal photography for Superman: The Movie began in March 1977 at Pinewood Studios in England (The New York Times).
  • Kidder was cast in 1976 and spent much of 1977 on set, commuting between London and the U.S.

How old was Christopher Reeve when he filmed Superman?

Reeve was 24 years old when filming began. He was 25 when the film was released. The age difference between the two — five years — was larger than what audiences might have guessed.

Bottom line: Kidder was 29 — a relative latecomer to stardom. For actors who don’t hit it big until their late 20s, her story is proof that a breakout role can happen at any age. For Superman fans, it’s a reminder that the franchise’s most iconic pairing was anchored by actors who were still figuring out their own careers.

The implication: Kidder’s age at breakthrough challenges the industry bias toward younger performers.

Who is considered the best Superman of all time?

Among fans and critics alike, Christopher Reeve remains the gold standard. His ability to switch between the bumbling Clark Kent and the heroic Superman has never been equaled in live-action portrayals.

Where does Christopher Reeve rank among Superman actors?

  • In most fan polls, Reeve ranks first — ahead of Henry Cavill, Brandon Routh, and Tom Welling (Wikipedia).
  • Critics point to his performance in Superman: The Movie and Superman II as the definitive versions of the character.

How does Margot Kidder’s Lois Lane relate to the best Superman?

Kidder’s Lois Lane is inseparable from Reeve’s Superman. Her portrayal — smart, tenacious, with a fierce vulnerability — was the perfect foil for Reeve’s dual performance. Without Kidder’s grounding presence, Reeve’s Superman might have felt too cartoonish. Together, they made the relationship work.

Why this matters

For studios looking to cast a new Superman, the lesson is clear: the Lois Lane casting is as important as the Man of Steel himself. A strong Lois makes a strong Superman. Kidder proved that in 1978, and the formula has held for nearly five decades.

For a woman who spent her final years fighting for mental health awareness and speaking out against injustice, that is perhaps the most enduring tribute.
