American actress Markie Post earned a lasting place in television history through memorable performances in popular sitcoms and dramas, most notably her portrayal of public defender Christine Sullivan in Night Court.
Born Marjorie Armstrong Post on 4 November 1950 in Palo Alto, California, she built a career spanning more than four decades, appearing in television series, films and animated productions. She died in Los Angeles on 7 August 2021, aged 70, following a nearly four-year battle with cancer that she largely kept private.
Her death prompted tributes from colleagues and fans who remembered her not only for her acting ability but also for her warmth and generosity.
Post was married to television writer and producer Michael A. Ross for nearly 40 years. The couple had two daughters, Kate Armstrong Ross and Daisy Schoenborn.
Early Life and Education in California
Post grew up in Walnut Creek, California, in a family with interests in science and the arts. Her father, Richard F. Post, was a scientist, while her mother, Marylee Post, was a poet. She also had two brothers, Rodney and Stephen.
She attended Las Lomas High School before enrolling at Lewis & Clark College in Oregon, where she earned a Bachelor of Arts degree.
Although she would eventually become a familiar face on television, Post did not immediately pursue a career in front of the camera. Instead, her first professional experiences came through work behind the scenes in television production.
How Markie Post Entered the Entertainment Industry
Post initially worked on game shows, gaining experience on productions including Split Second, Double Dare and Card Sharks. The work introduced her to the practical side of television and helped her develop an understanding of the industry.
Her acting career began in 1979 when she appeared in the television series CHiPs. That year, she also featured in Buck Rogers in the 25th Century, playing Joella Cameron in the two-part episode “The Plot to Kill a City”.
These early appearances helped establish her screen career and opened the door to more prominent roles in American television.
The Fall Guy Gave Her Wider Recognition
Post secured one of her first major recurring television roles in the action-adventure series The Fall Guy, starring Lee Majors.
Between 1982 and 1985, she played Terri Michaels, a bail bondswoman who became a familiar character to viewers of the show. Her performance helped raise her profile and demonstrated her ability to work comfortably in an ensemble cast.
During this period, she also appeared in The A-Team, playing Rina in guest appearances during 1983 and 1984.
However, an even more defining role was waiting for her in a courtroom comedy that would become one of the most recognisable television programmes of her career.
Night Court Established Her as a Television Star
Post became widely known for playing Christine Sullivan in NBC’s Night Court, a sitcom centred on the unusual cases and personalities of a Manhattan municipal court.
She joined the programme during its third season and became a full-time cast member. Her character was a principled, intelligent and determined public defender who often provided a moral counterbalance to the court’s more eccentric personalities.
Christine’s exchanges with Dan Fielding, the womanising prosecutor played by John Larroquette, became a notable part of the show’s appeal.
Post remained with Night Court until its conclusion in 1992. The role brought her widespread recognition and helped secure her place among the memorable television performers of the 1980s.
Hearts Afire and Other Memorable Television Roles
Following the end of Night Court, Post continued her sitcom career by starring in CBS’s Hearts Afire from 1992 to 1995.
She played Georgie Anne Lahti Hartman alongside John Ritter, taking on another prominent role in a network comedy.
Her television work later reached audiences who knew her from different genres. In the medical comedy Scrubs, she played the mother of Elliot Reid, introducing her performances to another generation of viewers.
She also voiced June Darby, the mother of Jack Darby, in the animated series Transformers: Prime. Her work on the programme ran from 2010 to 2013 and expanded her career into voice acting.
Among her film credits was the 1998 comedy There’s Something About Mary, alongside numerous television movies produced over the course of her career.
Markie Post Continued Acting During Cancer Treatment
Post received a cancer diagnosis in 2017 but continued working while undergoing chemotherapy.
Despite the demands of treatment, she appeared in a Lifetime Christmas film and took on a recurring guest role in the ABC comedy The Kids Are Alright.
Her decision to continue acting during her illness reflected her commitment to her profession. She kept much of her health battle private, and her death in August 2021 prompted renewed attention to the determination with which she continued her work.
Following her death, actress Sophia Bush paid tribute to Post, describing her as a supportive colleague and friend.
“She was a rock. A light. A great friend and a phenomenal scene partner,” Bush wrote. “She brought sunshine everywhere she went.”
The tribute reflected the affection Post inspired among people who had worked with her.
Her First Marriage and Long Relationship With Michael A. Ross
Post married her college sweetheart, Stephen Knox, in 1971. The marriage ended in divorce the following year.
In February 1982, she married Michael A. Ross, an actor and television writer and producer. Their marriage lasted until her death nearly four decades later.
Post and Ross raised two daughters, Kate Armstrong Ross and Daisy Schoenborn. Kate pursued acting and received the Best Supporting Actress award at the Creation International Film Festival in 2016 for her performance in Frog March.
Post also became a grandmother. At the time of her death, Daisy had a five-month-old daughter.
In a tribute shared on Instagram, actress Hilarie Burton Morgan remembered Post as someone who made loving others seem effortless. She also spoke about the affection Post showed when discussing her husband and daughters.
The comments offered a glimpse into the importance Post placed on her family life away from television.

Over four decades, she accumulated 76 acting credits and two producer credits, according to the profile information provided.
Her career covered several areas of entertainment, including sitcoms, action-adventure programmes, films, television movies and animated productions. Although Christine Sullivan remained one of her best-known characters, her wider body of work demonstrated her versatility as a performer.

A Lasting Legacy in American Television

Beyond her screen achievements, tributes from former colleagues highlighted the kindness and encouragement they associated with her.
Post’s death in 2021 ended a career that had spanned more than 40 years, but her performances continue to introduce her to audiences discovering her work for the first time.
