She came out of Woodmere like a match struck in a back hallway—quick flare, a little smoke, and then a long afterglow nobody bothers to label right. Actress for a while, publicist for longer, and in the middle she kept brushing up against famous men and famous machines and somehow never got crushed.
The Girl Before the Credit
She was born Muriel Eisenberg on February 19, 1935, which means she landed here during the tail end of the Depression’s hangover and grew up in America’s long, noisy rush toward TV screens and easy promises. Woodmere, New York isn’t the kind of place that shouts “stage lights,” but sometimes the quiet suburbs make a person itch worse. You learn early that the streets are too neat and the rules come too fast, so you start looking for doors with music behind them.
She found some. Carnegie Mellon took her in, School of Drama, class of 1958. The kind of training that works you over like a prizefighter’s mouth—rigorous, repetitive, and honest about pain. Before the diploma, she was already out in stock productions, billed as Muriel Eisenberg, doing the work that keeps theater alive in the places where nobody’s watching. Oregon Shakespeare Festival, among others, where you learn to speak lines into cold air and trust that meaning will hitch a ride.
And she danced. Katherine Dunham’s school, New York City. Dunham’s world doesn’t teach you to float. It teaches you to sweat with elegance, to understand rhythm as a kind of survival. In dance you don’t fake your way through a beat; the beat finds you, and if you’re lying, it tells on you.
New York, The Hungry Classroom
By the late ’50s she’s in New York doing what every serious young actress does—she tries to turn hunger into fuel. Now she’s “Margo” or “Margot” Bennett, because sometimes you change a name the way you change a coat: not to hide, but to fit the weather.
She studied with Lee Strasberg, which means long days in rooms full of smoke and ego and raw nerves, rolling around in your own memories until they came up shining or bleeding. It’s a kind of holy self-robbery. She was after truth, not decoration.
The work came in that steady, half-starved New York way: off-Broadway The Crucible in 1958, Equity Library Theatre’s Joan of Lorraine, and television drama anthologies that made actors old before their time. Armstrong Circle Theatre, The Doctors and the Nurses, CBS Repertoire Workshop—those shows were like boxing gyms for performers. No fancy matinee idol stuff, just craft. You show up, you bleed a little, you go home.
She did A Simple Heart on CBS, adapted from Flaubert, playing a woman named Virginie. Flaubert doesn’t hand you easy feelings. He hands you a quiet knife and asks you to cut clean. She did stock theater leads too—Gigi, The Diary of Anne Frank. Wide range there: champagne bubbles one night, history’s grief the next. That’s how you build a spine in the business.
Broadway and the Beatnik Greek
In 1963 she hit Broadway proper, original cast of The Irregular Verb To Love. She played Fedra, described as a Greek beatnik girl. Imagine that: ancient tragedy in a black turtleneck, cigarette ash falling on sandals. Broadway ran 115 performances—long enough to matter, short enough to leave a bruise.
The thing about Broadway in those years is it didn’t love you forever. It loved you while the curtain held, while the tickets moved, while the city believed. Then you were back out on the street again, looking for the next door with music behind it. She kept moving.
In 1964 she turned up on The Defenders, playing a sister of a man wrongly executed. TV then had teeth. It cared about morality and the messiness of law and dignity. If you played that kind of sister, you weren’t just delivering lines. You were carrying a family’s grief on live broadcast, hoping the cameras didn’t flinch.
One Film, One Strange Role
Hollywood didn’t grab her the way Broadway did. She didn’t zig-zag between studio pictures like other actors hunting for a foothold. She made one notable film in 1965: Who Killed Teddy Bear? She played Edie Sherman, mentally challenged sister of the main character. Supporting role, but those are the roles that can haunt you if you do them right. The story itself is dark, jittery, a city-nightmare kind of picture, and Edie lives in that shadowed corner where innocence and pain get forced into the same room.
Then she vanished from film for years. Not a scandal, not a failure—just life leaning somewhere else. Sometimes the work dries up. Sometimes you walk away before it makes you cheap. Sometimes you just get tired.
The Pivot Into Power
By the late 1960s she wasn’t acting regularly. Instead, she was working as a publicist for Paramount Pictures. That’s a different stage. In front of the camera you’re a spark. Behind it you’re a switchboard, controlling currents, leaning on the right words to make a story sell without breaking anyone’s face. Publicity is performance with no applause. You shape myth. You keep the machine oiled.
It also puts you close to the bloodstream of the business. You see who’s real, who’s terrified, who’s conning, who’s trying to make art inside a factory that measures bodies and box office.
Keir Dullea on a Riverboat
She married Keir Dullea on August 22, 1960. Two New York actors trying to make something steady while the ground kept shaking. They got married on a Mississippi riverboat in St. Louis, because Dullea was down there making his film debut in The Hoodlum Priest. That detail alone tells you what kind of romance it was: not lace and roses, but location schedules and heat and the river smelling like old stories.
Their careers pulled them apart by geography. He got film roles. She was on Broadway. Long-distance marriage in show business is like trying to keep a candle lit in wind. You can do it for a while if you hunch over it hard enough, but your shoulders get tired.
Malcolm McDowell and the Long Ride
In March 1969 she met Malcolm McDowell through her Paramount job, handling publicity for his first movie If…. The kind of meeting that looks casual in hindsight and feels like a trapdoor in the moment. He was English, electric, a new kind of dangerous for American studios then. They started a long-distance relationship. These are the relationships built on late-night phone calls, airport breath, the weird sadness of hotel rooms, and the occasional bright weekend that makes you believe in it again.
They lived together for several years. In 1973 they both appeared in O Lucky Man!—she in a brief, uncredited moment as a Latina coffee bean picker right at the start, him as the movie’s crooked, wiry center. She traveled with him to Cannes that year to promote it. Cannes is champagne and sharks. You smile for photographers while you feel your shoes cutting your feet.
In 1975, they got married in London. Reportedly she gave up acting around then to chase something she called an “uncomplicated long-lasting marriage.” Whether that line is exact or not, the feeling tracks. Some people don’t quit acting because they lack hunger; they quit because their hunger changes shape.
The Divorce, the Aftermath, the Quiet
By 1978 McDowell was filming Time After Time in California and fell in love with Mary Steenburgen. It happens like that in this world—your partner goes to work, comes home different. Bennett and McDowell divorced in September 1980. You don’t need dramatic language to explain it. The machine rolls, people change seats.
After that, she lived between Los Angeles and New York City. Two cities that speak different dialects of the same dream. LA is the dream stretched out in sunlight; New York is the dream clenched in cold fists. Some people can’t stop orbiting the centers where their lives were lit once.
What She Leaves Behind
Her acting years were short—1957 to 1973, if you count the official run—and her filmography is slim on paper. But paper isn’t the point. She was part of that mid-century ecosystem where theater and TV trained you like a craftsperson, not a celebrity. She worked when the jobs weren’t safe, weren’t glamorous, weren’t guaranteed. She played roles that asked for humanity instead of decoration.
Then she stepped into publicity—another kind of authorship. Some people need the spotlight. Others learn to move the spotlight around and make it mean something.
Margot Bennett is one of those stories that doesn’t end with a grand curtain call. It ends with a person who survived the rooms, learned the angles, loved a couple of complicated men, and kept her own name steady through all the costume changes. She burned bright, stepped sideways, and kept walking. In show business, that’s its own kind of victory.
