Marni Joan Bakst was far more than the longtime wife of The Shawshank Redemption actor William Sadler. She was an accomplished stained-glass artist, a feminist, a mother, an antiques enthusiast and a creative woman whose work was exhibited professionally long before Hollywood audiences became familiar with her husband. Marni and William married in 1978 and remained together until her death from cancer on December 18, 2024, after more than 46 years of marriage.
Her life was mostly private, which explains why many fans know William Sadler’s films but know surprisingly little about the woman who shared his life for almost half a century.
Marni’s story takes us from New York City’s Upper West Side to an East Village stained-glass studio, art galleries, marriage, motherhood, antiques collecting and finally a quiet life in New York’s Hudson Valley.

Who Was Marni Joan Bakst?
Marni Joan Bakst was an American artist whose main professional medium was stained glass.
Today, online searches for her name are usually connected with William Sadler because he became a widely recognized character actor through movies such as Die Hard 2, Bill & Ted’s Bogus Journey and The Shawshank Redemption.
But Marni had built a creative career of her own.
The Getty Research Institute’s Union List of Artist Names officially identifies Marni Bakst as an American 20th-century stained-glass artist.
That is an important detail.
She was not simply someone who enjoyed making art at home. Her work entered professional galleries, exhibitions and specialist publications.
Marni Grew Up on New York’s Upper West Side
Marni was born and raised in New York City.
Her obituary says she grew up on Manhattan’s Upper West Side, a neighborhood known for its mixture of culture, architecture, music, theatre and artistic life.
Growing up in New York would eventually fit perfectly with the direction her life took.
She became an artist.
She opened a studio in the East Village.
And she married an actor who was beginning his own career in New York theatre.
Before that happened, however, Marni pursued higher education.
Marni Joan Bakst’s Education
Marni attended the University of Chicago and later the California College of Arts, according to her published obituary.
Her education helped lead toward an artistic career focused on stained glass.
Working with stained glass is far more complicated than simply painting a picture.
An artist has to think about light.
Pieces of coloured glass have to work together when sunlight passes through them. The lead lines become part of the design, and the finished piece can look dramatically different depending on where it is installed.
Marni became good enough at this unusual art form to establish her own professional studio.
Her East Village Stained-Glass Studio
Marni opened a stained-glass studio in New York City’s East Village.
William Sadler later remembered that when he met her, she was already doing very well as an artist. She was exhibiting her work in galleries and working from a studio on Fifth Street in Manhattan.
That detail changes the usual way their relationship is sometimes described.
Marni did not meet a famous Hollywood star and then become connected with the arts through him.
When William entered her life, Marni already had her own artistic career.
In fact, during those years William was still building his career as a stage actor.
Both were young artists trying to make a life in New York.
Marni’s Work Reached the Heller Gallery
Marni’s stained-glass work earned serious attention.
Her obituary notes that her work was shown at the Heller Gallery, an important New York gallery associated with contemporary glass art.
Her designs were distinctive enough to attract attention beyond local exhibitions.
Her work also appeared on the cover of Stained Glass Magazine.
For an artist working in such a specialized field, that was a meaningful achievement.
It meant people inside the stained-glass community knew her work.
Marni Bakst Was Part of the Contemporary Glass-Art Movement
Marni’s name appears in historical material about modern stained-glass art.
A Canadian stained-glass bibliography records her among the artists included in the 1982 exhibition Fresh Steps in Glass at the Art Gallery of Hamilton. The review grouped her with artists experimenting with non-representational stained-glass work.
That tells us something interesting about her style.
Traditional stained glass often makes people think of churches, saints and religious scenes.
Marni was part of a generation exploring more abstract and modern possibilities for the material.
Glass itself could become sculpture.
Colour could be the main subject.
Light could change the work throughout the day.
For a creative person, there were endless possibilities.
Marni Also Received Support for Public Art
Historical records from the New York State Council on the Arts show Marni Bakst connected with a $10,000 public-art commission for leaded glass during the 1984–1985 funding period.
The project involved the Cooper Square Community Development Committee and Businessmen’s Association.
That is another strong piece of evidence showing that Marni’s career was professional and respected.
She was not known nationally in the same way her husband eventually became known.
But fame and artistic achievement are not the same thing.
Marni had genuine standing in her own field.
How Did Marni Bakst Meet William Sadler?
The story of their first meeting is wonderfully specific.
William later said that a mutual friend named Mark Simon introduced them.
At the time, William was performing in Henry V through Shakespeare in the Park in New York.
Marni came to see the play.
The date was July 3, 1976.
Afterward, Marni and William sat on a stone wall in Central Park and watched fireworks together. William remembered the date because it was the night before Independence Day.
It is difficult to invent a more New York beginning to a relationship.
A Shakespeare performance.
Central Park.
Fireworks.
Two young artists.
And neither could have known they were beginning a relationship that would last for nearly half a century.
William Sadler Was Still a Struggling Actor
William was nowhere near Hollywood fame when he and Marni met.
He was working in New York theatre and living cheaply with another actor.
In his later interview, William recalled that his share of the rent at the time was only around $75 per month.
Marni, meanwhile, had her stained-glass studio nearby.
Their relationship developed during a period when both were still working to establish themselves creatively.
That makes their marriage story especially interesting.
Marni was there before Die Hard 2.
Before Bill & Ted.
Before The Shawshank Redemption.
Before Roswell.
She knew William long before millions of movie fans knew his face.
Marni Bakst and William Sadler Married in 1978
Marni and William married on May 6, 1978.
Decades later, William shared a photograph from the morning of their wedding.
In the picture, the young couple are holding coffee mugs and smiling.
When he reposted it for their 45th wedding anniversary in 2023, William wrote affectionately about still bringing Marni coffee decades after the photograph was taken.
It is a very ordinary little detail.
And perhaps that is why it feels meaningful.
Famous marriages are usually documented through premieres and award ceremonies.
William remembered coffee.
A Marriage That Lasted More Than 46 Years
Marni and William remained married until her death in December 2024.
From May 6, 1978, to December 18, 2024, their marriage lasted more than 46 years.
During those decades, William’s acting career changed dramatically.
He moved from stage work into films and television and became one of Hollywood’s most recognizable character actors.
Marni occasionally accompanied him to public events.
One famous photograph shows the couple attending the Beverly Hills premiere of The Shawshank Redemption in September 1994.
But she never seemed interested in becoming a celebrity simply because her husband was one.
Her identity remained tied to art, family and her own interests.
Who Is Marni and William Sadler’s Daughter?
Marni and William had one daughter, Sadler Colley Bakst.
IMDb and William’s biographical records identify Sadler as their only child.
The unusual first name “Sadler” carries her father’s family name directly into the next generation.
Marni’s obituary shows that her family later expanded again.
At the time of her death, she was survived by her daughter, her son-in-law Daniel Hallock, and two grandchildren, Jack Ransom and Josie Rocket.
That means Marni’s later years included another role beyond artist, wife and mother.
She was also a grandmother.
Marni Joan Bakst Had a Small Acting Credit
Interestingly, IMDb also lists Marni as an actress.
Her best-known credited screen appearance was in the 2001 movie Skippy, in which she played a character named Francine.
Acting was never the career for which Marni became best known.
Her husband owned that side of the family’s professional life.
Still, the credit provides another little connection between their creative worlds.
Marni understood visual art.
William understood performance.
And occasionally, those worlds overlapped.
Marni Later Became Interested in Antiques
Years after her stained-glass work, Marni developed another major interest.
She began buying, selling and collecting antiques.
Her obituary specifically mentions antiques as one of the passions that occupied her later years.
In some ways, the transition makes perfect sense.
A stained-glass artist learns to notice materials, craftsmanship, colour, age and design.
An antiques collector uses many of the same instincts.
What is this object?
Who made it?
How old is it?
Why was it designed this way?
What story has it carried through time?
Marni seems to have spent much of her life surrounded by objects with stories.
William Sadler’s Description of Marni
When Marni died, William described her publicly in a few simple words.
He remembered her as an extraordinary artist, feminist, wife and mother.
Those words are useful because they came from someone who knew her for nearly five decades.
“Artist” acknowledges the career she built.
“Feminist” tells us something about her values.
“Wife” reflects their long partnership.
“Mother” recognizes the family they built together.
It is a much fuller description than simply calling her “William Sadler’s wife.”
Marni Joan Bakst’s Cancer Battle
Marni spent the final two years of her life battling cancer.
William announced her death publicly on December 19, 2024, explaining that she had died the previous morning after the two-year illness.
She died on December 18, 2024, at her home in Verbank, New York.
Her obituary says William and their daughter were beside her.
Marni was 75 years old.
For a family that had shared decades together, her loss naturally marked the end of an enormous chapter.
William’s public message made clear how difficult it was for him to immediately put that grief into words.
Why Marni Joan Bakst Still Matters in 2026
Marni died in 2024, so articles that describe what she is “doing now” in 2026 are incorrect.
The better question is: What remains of her story today?
Quite a lot.
Her name remains recorded by the Getty Research Institute as a stained-glass artist.
Historical art records document her exhibitions.
New York arts records preserve evidence of her public commission.
Her family remembers her.
And William’s stories preserve the human side of their long marriage.
In 2026, renewed interest in Marni often begins with William Sadler.
But it does not need to end there.
She Had Her Own Identity Before Hollywood Fame
This may be the most important thing to understand about Marni.
She was not a woman whose life began when she married a successful actor.
She was already creating.
Already exhibiting.
Already working.
Already building a professional identity.
When she and William met in 1976, they were both artists.
Their mediums were simply different.
He used characters, scripts and stages.
She used glass, lead, colour and light.
Eventually William’s work became known to millions.
Marni’s became known to a smaller art world.
But both lives were creative ones.
Final Thoughts
Marni Joan Bakst lived a life that was creative, private and deeply connected with family.
Born in New York City in 1949, she grew up on the Upper West Side, studied at the University of Chicago and California College of Arts, and later opened her own stained-glass studio in Manhattan’s East Village.
Her art appeared at Heller Gallery, on the cover of Stained Glass Magazine and in exhibitions devoted to contemporary glass. Historical records also document a New York public-art commission connected with her leaded-glass work.
Then there was William Sadler.
They met in 1976, watched fireworks together in Central Park, married in 1978 and built a life that lasted more than 46 years.
They became parents to Sadler Colley Bakst and later grandparents.
Marni eventually moved into antiques while remaining the woman William remembered as an artist, feminist, wife and mother.
She died on December 18, 2024, following a two-year battle with cancer.
In 2026, her story deserves to be remembered for something bigger than being married to a famous actor.
Marni Joan Bakst was an artist in her own right.
