Greta Thyssen: The Hollywood Bombshell Who Lived in Marilyn Monroe’s Shadow but Left Her Own Mark on Cinema

Greta Thyssen, the Danish beauty queen who crossed the Atlantic dreaming of Hollywood stardom, lived a life that blended glamour, scandal, resilience, and remarkable showbusiness success. Though best known today for her work as Marilyn Monroe’s stand-in and her slapstick turns with The Three Stooges, Thyssen’s journey through mid-century American entertainment is a story far richer — and far more dramatic — than the industry ever acknowledged.

Born Grethe Karen Thygesen on March 30, 1927, in Hareskovby, Denmark, Thyssen grew up far from the glitz of California. Her path to fame ignited in 1951 when she won the title Miss Denmark, a victory that put her on Hollywood’s radar during a time obsessed with platinum-blonde starlets modeled after Betty Grable, Marilyn Monroe, and later Jayne Mansfield. Eager to join them, Thyssen sailed for the U.S., ready to transform herself into America’s next pin-up sensation.

Following Marilyn Monroe — Literally

Thyssen arrived in Hollywood strategically positioned to become the next blonde icon. Studios were searching for women with Monroe’s curves and charisma, and Thyssen — statuesque, luminous, impeccably photogenic — fit the mold perfectly. She was soon hired as Marilyn Monroe’s double in the 1956 film Bus Stop, a job requiring her to mimic Monroe’s movements, presence, and unmistakable silhouette.

Though doubling for Marilyn offered visibility, it also branded Thyssen as part of Monroe’s shadow — a role Hollywood rarely let women escape. Still, Thyssen pushed forward, landing roles of her own in films such as Accused of Murder (1956), Terror Is a Man (1959), Three Blondes in His Life (1961), and the cult sci-fi favorite Journey to the Seventh Planet (1962).

The Three Stooges and the Golden Age of Slapstick

However, it was Thyssen’s appearances in Three Stooges short films — Quiz Whizz, Pies and Guys, and Sappy Bull Fighters — that cemented her in pop-culture memory. Her statuesque beauty and comic timing made her a perfect contrast to the Stooges’ absurd antics.

In one famous scene, she endured a full cream pie thrown directly into her face — a moment fans still reference as one of the most glamorous pratfalls the Stooges ever staged. It was a performance that revealed Thyssen’s willingness to laugh at herself in an era when Hollywood rarely allowed its ingénues to break their porcelain image.

From 1956 to 1958, she also became a familiar face in American living rooms as the original Pirate Girl on the hit game show Treasure Hunt, assisting host Jan Murray as contestants opened miniature treasure chests packed with prizes or hilarious misfortune.

A Deportation Scare and a Fight to Stay in America

One of the most dramatic chapters of Thyssen’s life unfolded off-screen. On October 5, 1953, U.S. authorities ordered her deported for violating her visitor’s permit — which had expired that March — and for taking acting jobs while still classified as a tourist.

The threat of deportation made national headlines. For a rising star, the scandal could have ended her career before it began. But Thyssen fought back, navigating lawyers, immigration hearings, and public scrutiny. Eventually, she remained in the country and reclaimed control of her career, proving a quiet but powerful resilience.

Hollywood Roles, Broadway Success, and a Sudden Goodbye

Thyssen’s acting career thrived through the late 1950s and early 1960s. She made guest appearances on Dragnet and Bachelor Father, and played Roxy Howard in the Perry Mason episode “The Case of the Nervous Accomplice.” She also took over Broadway roles, including replacing June Wilkinson in Pajama Tops, showcasing her comedic range and stage presence.

Yet by 1967, after appearing in the musical comedy Cottonpickin’ Chickenpickers, Thyssen abruptly retired from acting at just 40 years old. Hollywood changed. The blonde-bombshell archetype faded. And Thyssen, always more private than her on-screen persona suggested, chose a quieter life.

Love, Loss, and a Life Lived on Her Terms

Thyssen married four times. Her final marriage — to engineer Theodore Guenther, which lasted until his death in 2000 — brought her stability and a daughter, Genevieve Juliette Guenther, whom she adored.

She lived her later years in Manhattan, stepping away from fame but not forgotten by fans of classic cinema. On January 6, 2018, Greta Thyssen died of pneumonia at age 90 — a long life marked by beauty, comedy, controversy, and determination.

A Legacy Revived

Though she never achieved the global superstardom of Monroe or Mansfield, Greta Thyssen left behind a remarkable legacy: a woman who embodied the glamour of the Golden Age while forging her own unpredictable path.

She was more than a look-alike. More than a scream queen. More than a pin-up.
She was one of Hollywood’s last true bombshells — and a star who deserved far more than history ever gave her.
